GC-3804 user manual
1 Function Introduction
1.1 FunctionOverview
The GC-3804 module is an I/O module with integrated 4-channel temperature
sensor (PT100) input channel. The module can be used to collect temperature
information in real time and send the collected values to the GCAN-PLC-400
or GCAN-8000/8100 series couplers via the internal bus. This module can be
used with any other GC series IO module to achieve the collection and
processing of analog data in industrial automation or distributed control
systems.
