Installation Guidelines
- Ensure the PLC system is powered down before inserting or removing the module from the rack.
- Use shielded twisted-pair cabling for all analog signal connections to minimize EMI/RFI interference.
- The module does not provide power to 2-wire transducers; ensure an external power supply is used in series with the loop.
- Maintain proper grounding practices to ensure the integrity of the floating isolation barrier.
- Ensure adequate ventilation in the cabinet to dissipate the 3 W typical power loss.
