| DM2436AB 是一只以 16 位元微處理器為計(jì)算核心，全數(shù)位化量測、顯示、校正、輸出的多功能電力表。因其微處理器之快速工作脈波 (16MHz) 及快速取樣，能夠提供高準(zhǔn)確度的量測。 DM2436AB 除了能以單一表量測所有電力單位 (V、A、W、VAR、PF、WH、VARH、Hz) 外，還具有*大值、*小值量測，及設(shè)定值接點(diǎn)輸出等功能。在通信介面上，有串列的 RS-232 或 RS-485 可供選擇，以世界上極通用的 MODBUS RTU 為通信協(xié)定，提供使用者更方便的搭配。

RS-232C CONNECTION
The figure bellow illustrates the wiring requirements for connecting the DM2436AB using RS-232C communications. This can include a local direct connection to a
computer or other device. The RS-232C standard allows only a single point-to-point communications connection. Using this method, only one RS-232C equipped device may be connected to the serial port of the computer, or other device.The cable used between the computer is a standard RS-232Ccommunications cable with a maximum length of 50 feet (15.2m). | |
RS-485 CONNECTION
RS-485 communications allows multiple devices to be connected on the same bus. Up to 30 devices can be connected on a single RS-485 bus, which consists of a shield twisted pair cable. The overall length of the RS-485 cable connecting all devices cannot exceed 4000 ft (1219m). |
