Product details
Product Introduction
ADM-4280-C is an 8-channel 0~20mA/4-20mA/0-10V analog signal data acquisition module, which can be widely used for signal acquisition and monitoring of industrial field equipment. When "C" is I20, it represents an analog input of 0~20mA/4-20mA current. When "C" is V10, it represents an analog input voltage of 0-10V. The analog signal adopts a single ended input method, and the communication interface adopts RS-485 interface. It supports the standard MODBUS-RTU protocol and can be directly connected to configuration software, PLC, DCS industrial control touch screen, etc.
Product Specifications

Definition of module indicator lights
1. POWER: Power status indicator, constantly on/normal power supply
2. COMM: RS-485 interface communication indication, flashing/module is sending and receiving data
Use default communication parameters
When the communication parameters of the module (module address, baud rate, parity) are forgotten, short-circuit the Initiat and VS - pins and power on the module again. At this time, the module uses the initial communication parameters (9600, N, 8, 1, address 01) for communication.
When the Initiat and VS pins are disconnected, the module communicates using the communication parameters set by the user.
Module Register Address Description
