Modbus family includes bus couplers

Three additions to the Inline Modular family, the Modbus TCP/UDP and Modbus RTU/ASCII bus couplers, as well as a backplane expansion module, broaden the company's offering compact I/O solutions. The 80-mm-wide Modbus TCP/UDP incorporates eight digital inputs, four digital outputs and a built-in Ethernet switch, while the similarly sized Modbus RTU/ASCII includes eight digital inputs, four digital outputs, and an RS-485 D-Sub connection for Modbus.

Both devices feature diagnosis LEDs. The backplane expansion module enables the expansion of the local bus onto a second rail within the control cabinet. Maximum capacity is 63 devices. (Contact company for pricing—available now.)
