S4000C
9
The following General Monitors Modules provide power connections for the Model S4000C, but
need a customer supplied DC source:
•
DC110 Eight-Channel Readout/Relay Display Module
•
TA102A Trip Amplifier Module without a PS002
Since the Model S4000C 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.
The maximum distance between the Model S4000C and the power supply is 3000 feet or 910
meters (each cable run should be as short as possible). See Section 9.3.3 for cable length
specifications. To c24VDC to the Model S4000C, connect the red wire to TB2, position
9. Connect the black wire 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 Model S4000C Intelligent Sensor provides a 4 to 20mA 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 20mA
signal provides for control room or other locations remote to the Model S4000C to display
indications of operation and alarm conditions. To connect the 4 to 20mA output signal with
another unit, connect the wire into TB2, position 1, labeled 4-20mA OUT. For making output
signal connections to display devices (Table 4), refer to the specific manual for that device.
