TRP-C24H     Isolated  16-channel Open Collector Modbus TCP Module

                      Support  TRP-ASCII, Modbus RTU/ASCII  protocol



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.


  • Wide input range DC power supply.

  • Automatically determine 3 TRP-ASCII and Modbus RTU/ASCII communication protocol.

  • 16 TCP Port can be open at the same time.

  • Heart Beat function ensures a reliable communicating connection.

  • Maximum 8 sets host IP that limits network access.

  • Each channel supports the mono stable circuit and auto save the time period to EEPROM.

  • Support Virtual-COM mode.

  • IO status can be set in the boot!

  • WEB PAGE can be directly output and read IO status.

  • Easily update the firmware using the Internet.
