Specifications

TRP-C29
Isolated 8 CH. DI and 8 CH. O.C
RS485 Module
RS485 Remote IO
TRP-C29 provides with 8 optical isolated digital
input channels and 8-channel digital output open
collector. All channel features screw terminals for
convenient connection of field signals as well as
LED’s to indicate channel status. Input channels
are equipped with 3750Vms DC isolation, and
surge protection on RS485 data lines that protect
the module and devices against high power
voltage input and ground potential differences.
For easy user access, TRP-C29 can enter
configuration mode and self-test mode with outer
dip-switch. TRP-C29 support both ASCII and
Modbus protocol, with a full set of command, dual
watch-dog, and auto reset function the module
can be bi-directionally remote controlled by PC in
ASCII or Modbus RTU protocol.
