Allen Bradley 1492-IFM40D24 Digital Interface Module

Allen-Bradley 1492-IFM40D24 Digital Interface Module

The Allen-Bradley 1492-IFM40D24, also cataloged as the 1492-IFM40D24 digital interface module, serves as a 40-point termination assembly for discrete 24 VDC signals in PLC control systems.

Hardware Specifications

I/O Density Scaling

The 1492-IFM40D24 supports high-density I/O scaling by consolidating 40 discrete 24 VDC signals into a single termination module. This reduces wiring complexity and panel space requirements. Channel isolation ensures deterministic signal routing, while screw-clamp terminals provide secure retention for field wiring.

Frequently Asked Questions

Q: How many signals can the 1492-IFM40D24 terminate? A: It provides 40 discrete 24 VDC termination points.

Q: Is the module powered independently? A: No, it is a passive termination module; it routes signals without consuming significant power.

Q: Can the module be mounted in any orientation? A: It is designed for DIN rail mounting; orientation should allow access to terminals and wiring bend radius.

Field Installation Guidelines

• Mount the module on a DIN rail inside control panels.
• Route high-voltage conductors separately from low-level digital wiring.
• Ensure proper torque on screw terminals to avoid intermittent connections.
• Maintain ambient temperature within 0 to 60 deg C for stable operation.
• Verify channel isolation before commissioning to prevent cross-talk.
