A Modbus RTU/ASCII TCP/UDP bus coupler has eight digital inputs, four digital outputs, a built-in Ethernet switch, and an RS-485 D-SUB connection for Modbus communications. The coupler uses BootP to assign IP addresses. It is 80 mm wide.
A backplane expansion module expands the local bus onto a second rail within the control cabinet. It has a maximum capacity of 63 devices for multiple expansions on a single bus station. An incorporated power terminal supplies all 24 Vdc voltages required for the low-level signal of an Inline station.
