The SNAP-AIMA-iSRC-FM is an Opto 22 analog current input module that provides two isolated channels of \(-20\text{ mA}\) to \(+20\text{ mA}\) with built-in loop sourcing capability and Factory Mutual (FM) hazardous location approval. It acts as a rugged, high-density component of the SNAP PAC control and I/O system.
Key specifications and features include:
- Built-in Loop Sourcing: Requires only a single 24 VDC power supply to source 24Vfor two independent 4–20 mA loops.
- Channel-to-Channel Isolation: The two input channels and their loop sources are completely isolated from one another.
- Hazardous Location Approved: Features the "-FM" suffix, indicating Factory Mutual approval for use in hazardous environments.
- System Compatibility: Mounts on a SNAP PAC mounting rack and is fully compatible with SNAP PAC brains, rack-mounted controllers, and Allen-Bradley Logix PLC
