TRP-C26 16-CH isolated digital input RS-485 module ,
Support ASCII and Modbus RTU protocol.
Introduction
TRP-C26 provides 16 optical isolated digital input channels that allow you
to input the logic signal from 0 to 30V DC. All channel features screw terminals
for convenient connection of field signals as well as LED’s to indicate channel status.
All inputs are equipped with photo-couplers to protect the module
against high voltage spikes, as well as ground potential differences. For easy user access,
TRP-C26 can enter configuration mode and self-test mode with outer dip-switch.
TRP-C26 support both ASCII and Modbus protocol, with a full set of command,
dual watch-dog, and auto reset function the module can be remote controlled by PC
in ASCII or Modbus RTU protocol .
