Technical FAQ
Q: Can this module power 2-wire loop transmitters?
A: Yes. The module provides ≥19.0 V @ 20 mA, sufficient for standard 2-wire loop-powered field devices.
Q: Why is channel isolation important?
A: Isolation prevents electrical noise or faults on one channel from affecting other channels or the control system, improving reliability and data integrity in industrial environments.
