Description
Introduction:
This Rs485 Analogue module is used through Modbus communication protocol, in this instrument user can do calibration of four channels and read and write Modbus ID this can be done through Modbus, this instrument easy to use with PLC/DC. It has 4 nos 0-10vDc/4-20mA output optical and Galvani isolated and user can be using every channel via standard Modbus protocol. And it has 4 nos Analogue input like AC/DC V /4-20mA DC. Its operating power supply voltage is 24vdc.
Modbus communication protocol:
1. Baud Rate: 9600 B/S
2. Data Bits :8
3. Party: None
4. Stop Bit: One
5. Communication Mode: RTU 8 Bit
