TRP-C28H
Isolated 4 DI and 4 AC Relay
Modbus TCP Module
Ethernet Remote IO
TRP-C28H an Isolated Digital Input with counter and
AC Relay Modbus TCP Module, provides 4 channels
optical isolated digital input channels and counter and
4 Channel AC Relay that allow you to input the logic
signal from +/- 0 to 30V DC and 5A /250V AC relay on
network, it supports 3 communication protocol, TRP-
ASCII, Modbus RTU / ASCII, TRP-C28H can be easy
and convenient to use application supports Modbus.
Software engineers can use the TRP-ASCII or
Modbus RTU command set quickly and easily
integrated into the self-development program, such as
Microsoft VB, VC...
TRP-C28H built-in independent IP, WEB-browsing
more convenient to rewrite the configuration and
collect information through computers, tablet
computers, smart phones, will be available!
TRP-C28H built-in watchdog function to ensure the
normal operation of the module, and a built-in voltage
monitoring to ensure that the boot, excellent and
advanced hardware for harsh environment.
TRP-C28H with another TRP-C28H remote control
directly, do not need to run the software and
equipment.
TRP-C28H also offers the maximum connection 16
host client to link the network server that is easy to
operate in Modscan32 ,Modbus Poll,CAS Modbus
Scanner and SCADA ...application uses TCP mode
and Virtual-COM mode.
