The TRP-C24 is an isolated output open collector RS-485 module with 16 digital output channels. This allows the output open collector signal (100mA) to drive devices on the RS-485 network.

All channels feature screw terminals for convenient field signal connection along with LED displays to indicate channel working status.

All outputs are equipped with photo-couplers to protect the module against high voltage spikes, as well as ground potential differences.

For easy user-access the TRP-C24 can enter configuration mode and self-test mode with outer dip-switch.

The TRP-C24 supports both ASCII and Modbus protocol. With a full set of commands, dual watch-dog and auto reset function, the module can be remote controlled by PC in ASCII or Modbus RTU protocol.
