Specifications
TRP-C68
Isolated 8 CH. AI RS485 Module
RS485 Remote IO
TRP-C68 , an 8-channel Analog to Digital
Converter (ADC), takes an analog input signal
and converts the input into a digital output signal.
It accepts analog input-a voltage or a current-and
support the sample rate in “ Normal ” or “Fast”
mode. All channels feature screw terminals for
convenient connection, and LED’s to indicate
channel status. All inputs are provided with
isolation and surge protection to protect the
module against high voltage spikes, as well as
ground potential differences. TRP-C68 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.
