Features:
- Four isolated current-input channels cover −20 to +20 mA signals.
- 0.8 µA resolution and 23 ms maximum freshness support responsive acquisition.
- SNAP PAC mounting and configuration provide a compact I/O path.
Opto 22 SNAP-AIMA-4 is supplied for four-channel current-loop acquisition in a SNAP PAC control or monitoring system.
Its isolated channels convert bipolar loop signals into controller data while maintaining the common-mode and survival limits specified for the module.
Select the SNAP mounting position, shielded conductors and controller configuration together; field wiring must respect the input polarity and torque limits.
The SNAP-AIMA-4 is an Opto 22 analog input module; Apter Power supports sourcing, documentation and configuration checks.
