Overview
The Allen-Bradley 1492-AIFM8S-3 is an analog interface module designed for Rockwell Automation control systems. This feed-through wiring module provides eight isolated channels for analog signal conditioning and connectivity. The dual-interface design—D-shell connector on the control side and screw terminals on the field side—enables straightforward installation and supports modular replacement in panel environments.
Key Features
- Feed-through design with 8 isolated analog channels
- 3 screw terminals per input for field-side wiring security
- D-shell cable connection to control system
- Reduces wiring errors and installation time
- Supports CompactLogix and ControlLogix systems
- Operating temperature range 0–60°C
Technical Specifications
The module operates at 24 V DC supply and features isolated inputs to prevent ground loops and signal noise. Each channel provides three-terminal connectivity for standardized industrial field installations. The fixed terminal block design ensures repeatable, secure connections without drift or loosening.
Typical Applications
- Analog signal conversion in manufacturing and process control
- Sensor and transmitter interfacing (4–20 mA loops, 0–10 V inputs)
- Panel-mounted wiring distribution for CompactLogix platforms
- Food and beverage, automotive, and discrete manufacturing systems
- Equipment retrofits requiring modular I/O expansion
Compatibility & Replacements
The 1492-AIFM8S-3 integrates seamlessly with Allen-Bradley CompactLogix and ControlLogix systems via standard Ethernet or panel-mounted configurations. It is part of the 1492 series wiring and interface modules. Related products in the series include the 1492-AIFM8-3 (non-isolated version) and 1492-AIFM8TC-3 terminal connector alternative. Verify controller firmware and I/O module slot compatibility before installation.
