3.5.3 DC Power and COM Connections
The customer must provide primary DC power unless one of the following General
Monitors modules is being used with the S4000CH:

TA102A trip amplifier module with a PS002 power supply & relay module
The following General Monitors modules provide power connections for the S4000CH, but
need a customer supplied DC source:

DC110 Eight-Channel Readout/Relay Display Module

TA102A Trip Amplifier Module without a PS002
Since the S4000CH is designed to operate continuously, a power switch is not included, in
order to prevent accidental system shutdown.
NOTE:
Power must remain disconnected until all other wiring connections have been
made.
See Section 7.3.4 for cable length specifications.
To c24 VDC to the S4000CH, connect the red wire (+24V) to TB2, position 9.
Connect the black wire (Ground) to TB2, position 8.
For making power and ground connections to display devices see Table 2 and Table 3.

3.5.4 Analog Signal Connections
The S4000CH Intelligent Sensor provides a 4 to 20 mA output signal. It can be sent up to
9000 feet (2740 meters) to a General Monitors readout/relay display module, or an
industrial analog to digital converter, or a computer-based monitor, a PLC, a DCS, etc.
The 4 to 20 mA signal provides for control room or other locations remote to the S4000CH
to display indications of operation and alarm conditions.
