The TRP-C24H is a 16-CH open collect Ethernet I/O module with isolation.

It supports a feature of monostable,and it allows the user to adjust timer value from each channel, These value will be? autosave,and it is available from 100ms? to 25.5 sec.?

There are 3 protocols we supports that, it includes ASCII and Modbus TCP RTU / ASCII.

The watchdog function ensures running stable under harsh environment.

It can allows to connect 1~8 sets of host IP in the network security.
