TRP-C26
Isolated 16 CH. DI RS485 Module
RS485 Remote IO
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 .
