Quick Details

The Opto 22 SNAP-AIMA-i Analog Input Module is a high-performance industrial hardware interface engineered to monitor active current loops. Mounted on a shared system rack alongside a central processor, it converts analog sensor readings into structured system values. Featuring robust channel-to-channel, optical, and transformer isolation, the device actively breaks up ground loops and safeguards upstream electronics from voltage transients. Each board utilizes an onboard microprocessor to independently govern raw signal tracking and module health parameters.

l Number of Channels: 2 isolated analog current input paths.

l Input Range: Measures standard bipolar current from -20 mA to +20 mA.

l Logic Power Consumption: Draws 5 VDC @ 200 mA directly from the backplane rack.

l Input Impedance: Standard nominal resistance of 200 Ohms.

l Response Time: Captures system shifts in under 10 ms.

l Galvanic Isolation: Features 4000 V Optical, 1500 V Transformer, and 250 V Continuous Channel-to-Channel protection.

l Operating Temperature: Hardened to operate reliably from -20°C to 70°C (-4°F to 158°F).

Product Applications

l Process Variable Monitoring: Ideal for capturing telemetry data from active process sensors like pressure, flow, and level transmitter loops.

l Ground Loop Prevention: Deployed in sprawling facilities with disparate electrical grounding to isolate channels and prevent sensor signal distortion.

l Remote Distributed I/O: Couples with communication nodes to serve as an intelligent data acquisition unit for third-party Allen-Bradley Logix platforms.

l Harsh Industrial Automation: Installed in high-voltage switchgear cabinets or heavy machinery fields susceptible to severe electromagnetic noise.

Application

Refinery: Controls emergency shutoff valves to prevent fire and explosion.

Chemical Plant: Provides safety interlocks to automatically isolate hazardous pipelines.

Power Plant: Monitors boilers and turbines, triggering emergency shutdowns during unsafe conditions.

Pharmaceutical Plant: Protects critical reactors from temperature and pressure limits.

Fertilizer Plant: Safeguards high-pressure ammonia units to prevent gas leaks.
