RS485 module with 8 digital inputs and 8 digital outputs (TRP-C29)

Device with RS485 interface that has 8 opto-isolated digital inputs and 8 digital outputs. Each channel has a terminal connection and an LED indicating the status of the channel. The input channels are equipped with an opto-isolation DC of up to 3750 Vms. It supports the ASCII and Modbus communication protocols with a complete set of commands, dual watchdog and auto-reset function. The module can be bi-dDirectionally controlled remotely by a PC using either the ASCII protocol or the Modbus RTU.
