The Allen Bradley 1746SC-INI4VI is a high-performance isolated analog input module designed for Allen-Bradley SLC 500 control systems. It features four individually isolated channels capable of processing both current and voltage signals simultaneously in electrically noisy environments. The module offers 16-bit high-resolution converting capabilities and channel-selectable filtering, making it an ideal choice for high-accuracy industrial monitoring without compromising system price or processing speed.

(1) Input Channels: 4 channels (isolated current or voltage)

(2) Current Input Ranges: 0–20 mA, 4–20 mA

(3) Voltage Input Ranges: 0–5 V, 1–5 V, 0–10 V, ±10 V

(4) Backplane Current Required: 550 mA at 5 V; 0 mA at 24 V (typical)

(5) Electrical Isolation: 125 VAC continuous

(6) Operational Temperature: 0°C to 60°C (32°F to 140°F)

(7) Storage Temperature: -40°C to 85°C (-40°F to 185°F)

High Electrical Noise Environments:

Frequency converters, motor control centers, and assembly lines with significant electromagnetic interference.

Long-Range Sensor Monitoring:

Applications with remotely located sensors requiring high noise immunity.

Chemical Processing & Manufacturing Lines:

Precision analog signal acquisition for process monitoring and control.

Industrial Control Systems:

General monitoring of analog process variables such as pressure, temperature, flow, and level.
