I Description
This signal conditioner is a dual or quad-channel
analog input module with one discrete/relay out-
put per input channel and a Modbus interface. It
filters and linearizes RTD or resistance inputs
while providing isolation between input, output,
power, and network circuits. Lead wire compen-
sation and upscale/downscale sensor break
detection are standard. Low voltage AC and DC
power sources are supported with nonpolarized,
diode-coupled terminals.
The programmable inputs accommodate four
RTD types plus wide-range resistance signals.
Flexible discrete outputs operate as alarms or
on/off controllers. As limit alarms, each discrete
output can be configured with high and/or low
setpoints exclusively tied to an analog input
channel. Alarm trips function without host com-
munication enabling low-cost stand-alone alarms
as well as local backup for the primary control
system. Otherwise, on/off control is based on
commands issued by the host system.
Combining flexible transmitter functions, mixed
signal I/O, alarm support, and a network inter-
face in a single package, makes this instrument
extremely powerful. Multi-channel design adds
cost-efficiency and allows high-density mounting.
Plus, safe, rugged construction makes these
modules reliable for use in both control room
and distributed field I/O applications. Custom
module configurations are also possible (consult
factory for details).

I Description
This signal conditioner is a two-channel analog
input module with discrete outputs and Modbus
communication. It conditions periodic or pulse
waveform inputs and provides solid-state relays
for limit alarms or ON/OFF control.
Versatile inputs accommodate many applications
using TTL, magnetic pickups, proximity sensors,
or a variety of switches (high/low-side transistor,
dry contact, open drain, open collector). Bipolar
and unipolar waveforms are supported with a
selectable input bias that accepts both zero and
non-zero crossing signals. Voltage threshold and
relative hysteresis are also user selectable.
Inputs may also function as event counters with
separate microcontrollers for each channel. The
module counts pulses on the positive or negative
edge. It can wrap around to zero for continuous
counting, latch at a programmed count value
(setpoint), or automatically reset itself to zero
after reaching a setpoint value. Software controls
enable remote resets. A variety of filters help
remove noise, jitter, and other mechanical effects
to prevent false counts.
The discrete outputs can operate as independent
alarms or provide on/off control regulated by the
host system. As limit alarms, each output can be
set for high and/or low setpoints exclusively tied
to an analog input. These low cost modules are
ideal for standalone alarms as well as for local
backup of the primary control system.
I Special Features
I Standard Modbus RTU protocol with high-speed
RS-485 communication (up to 115K bps)
I Separate microcontrollers on each channel for
pulse counting and period measurement
I Solid-state relay outputs enable local limit
alarms or host-controlled on/off switching
I Bipolar and unipolar input signal support
I Programmable pulse counter functions
I Input filtering functions include hysteresis,
averaging, debounce, relay time delay, and
alarm deadband controls
I 4-way isolation (input, output, power, network)

I Description
These modules provide twelve discrete input
and/or output channels. Isolation separates the
I/O, power, and network circuits. Network
communication adheres to the industry-standard
RS-485 Modbus RTU protocol. Both AC and DC
power sources are supported with wide range,
nonpolarized, diode-coupled terminals.
The open-drain outputs are intended for current-
sinking or low-side switching applications. The
buffered inputs are active-low. These models are
the complement of the 904, 905, and 906 units
which have open-source, high-side output
switches and active-high inputs. Socketed pull-up
resistors are easily removed or exchanged to sat-
isfy your application requirements.
The 903MB model has twelve input/output
points that may be used as inputs or outputs on
a bit-by-bit basis. Outputs may be read back to
verify output settings.
Combining flexible I/O types, wide I/O ranges,
and a network interface in a single package,
makes this instrument extremely powerful.
Multi-channel design adds cost-efficiency and
allows high-density mounting. Plus, safe, rugged
construction makes these modules reliable for
use in both control room and distributed field I/O
applications. Custom module configurations are
also possible (consult factory for details).

I Description
These modules provide twelve discrete input
and/or output channels. Isolation separates
the I/O, power, and network circuits. Network
communication adheres to the industry-standard
RS-485 Modbus RTU protocol. Both AC and DC
power sources are supported with wide range,
nonpolarized, diode-coupled terminals.
The outputs are intended for current-sourcing or
high-side switching applications. The buffered
inputs are active-high. These models are the
complement of the 901, 902, and 903 units
which have low-side output switches and
active-low inputs. Socketed pull-down resistors
are easily removed or exchanged to satisfy your
application requirements.
The 906MB model has twelve input/output
points that may be used as inputs or outputs on
a bit-by-bit basis. Outputs may be read back to
verify output settings.
Combining flexible I/O types, wide I/O ranges,
and a network interface in a single package,
makes this instrument extremely powerful.
Multi-channel design adds cost-efficiency and
allows high-density mounting. Plus, safe, rugged
construction makes these modules reliable for
use in both control room and distributed field I/O
applications. Custom module configurations are
also possible (consult factory for details).
I Special Features
I Standard Modbus RTU protocol with high-speed
RS-485 communication (up to 115K bps)
I Twelve I/O channels in a single inch-wide unit
reduces system costs and saves panel space
I High-voltage, high-current, open-source
outputs enable direct (high-side) control of
external devices
I High-voltage buffered inputs monitor discrete
levels from a variety of industrial devices
I Tandem input/output circuitry (906 models
only) connects input buffers with open-source
outputs for convenient loopback monitoring of
the output state
I Watchdog timers provide a configurable
failsafe output state for use when host
I/O communication is lost
I Three-way isolation eliminates potential
ground loops between power, I/O, and
network circuitry
I Self-diagnostics monitor microcontroller activity
to detect operational failures (lock-up) and
execute a reset to restore communication

Operation
Model 4683-TTM-xF network repeaters
isolate and boost RS-485 signals allowing
communication signals to travel another 4000 ft.
Each repeater permits the addition of another 32
unit load to a network.
The repeater has two RS-485 “sides” known as
the A and B sides. The A side
typically connects to the network towards the
host and the B side connects to the extended
network. Functionally, the A and B sides are
equivalent.
Repeaters receive AC power through a 3-screw
terminal strip. Transient signal protection is
provided on both RS-485 sides.
When both RS-485 lines are idle, each side is
in receive mode. When a ‘1’ to ‘0’ transition is
detected (signifying a start bit) on either side,
the opposite side’s transmitter is enabled. The
transmitter stays enabled for one character’s time
(based on the baud rate switch setting). The
received character is then passed through.
For N2 or BACnet MS/TP bus ◆ Drives up to 32 RS-485 

devices ◆ Isolates and boosts signal up to 4000 ft.

BusWorks ® I/O Modules
for Profibus-DP
Acromag’s BusWorks 900PB series is a
high-performance line of network-ready
analog and discrete I/O modules. They
feature universal input/output ranges and
an inligent microcontroller to provide
extreme flexibility and powerful monitor-
ing and control capabilities. Select from a
variety of analog and discrete I/O models
to meet your application requirements.
Each module provides a direct network
interface for your I/O signals. Unlike
“block I/O” devices that combine large,
expensive processor blocks with snap-on
I/O terminal blocks, 900PB modules
handle the network interface and I/O
processing in one, compact multi-channel
module. This space-saving approach is
very cost-effective for systems that need
to add a small quantity of I/O channels at
existing control sites or network to new
remote sites.
To ensure high performance, modules
feature an advanced microcontroller
technology. On-board address switches
and automatic baud rate detection (up
to 12 Mbps) simplify installation. Four-
way isolation prevents ground loops and
increases noise immunity. Indicator LEDs
and self-diagnostics help you quickly
catch problems.
