TRP-C24
Isolated 16 CH. O.C RS485
Module
RS485 Remote IO
The TRP-C24, an isolated output open collector
RS-485 module, provides 16 digital outputs
channels that allow you output open collector
signal (100mA) to driven your devices on RS-485
network. All channels feature screw terminals for
convenient connection of field signals as well as
LED’s 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, TRP-C24 can enter configuration
mode and self-test mode with outer dip-switch.
TRP-C24 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.
