The Modbus I/O modules allow digital and analogue input values to be connected using the Modbus communication protocol. MS/TP (Master/Slave Token-Passing) based on the RS485 standard is used here. This allows a total bus length of 1,200m per segment with speeds of up to 76,800 bit/s. The I/O modules are optimally designed for interaction with the BACnet router UBR-01 | Mk II. By using the router, the modules can then be connected to IT networks.
