Modbus Protocol Serial Communications Card (Communication Modbus RTU) – SC1001
Communication Modbus RTU Card with Master/slave Modbus protocol. It manages the following Modbus variables: 512 Input variables, 512 Output variables, 1024 16-bit analogue variables. The values on to 4-20mA analogue cards can be transmitted to the DCS system.
Its Output supplies two independent connections, a RS485 Half Duplex and a RS232.
The analogue variables boast the engineered values relative to 4-20mA analogue cards.
