4. Connect sensor cable. Reference
Connect sensor cable to the module’s terminal block.
Important:
Follow these guidelines when wiring the module:
Use shielded communication cable (Belden8761) and keep length as short as possible.
Connect only one end of the cable shield to earth ground.
Connect all the shields to the earth ground at the SLC 500™ chassis mounting tab.
Single-ended source commons may be jumpered together at the terminal block.
Channels are not isolated from each other. All analog commons are connected together internally.
Common mode voltage range is ±10.25 volts. The voltage between any two terminals must be less than
20.5 volts.
The module does not provide power for the analog input transmitters or sensors.
Use a power supply that matches the transmitter (sensor) specifications.
