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 (Belden™ 8761) 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.
