Product Overview

The Allen-Bradley 1746-IM16 acts as a high-density digital AC input module engineered specifically for the SLC 500 Programmable Logic Controller (PLC) platform. This module monitors and routes high-voltage discrete signals directly from heavy industrial field equipment to the central processor backplane. It houses 16 independent input channels configured with a single electrical common terminal point, allowing for efficient group wiring inside high-voltage control cabinets.

The hardware interfaces directly with 200/240V AC nominal source lines, tracking the status of pushbuttons, limit switches, motor auxiliary contacts, and safety interlocks. By filtering raw electrical line currents into clean logic data, this card isolates the core logic system from heavy field voltage variations.

We supply this product exclusively as 100% brand new, original, and factory-sealed within its original factory box to guarantee maximum insulation resistance, uncompromised internal electronic components, and a full operational lifetime.

Engineering Advantages

High-Voltage Signal Consolidation: The module routes up to 16 high-voltage 240V AC lines into a single hardware slot. This high-density layout reduces the number of intermediate step-down relays needed to interface field equipment with the PLC, saving both panel space and component costs.
Low Heat Generation & Current Draw: Consuming only 0.085 Amperes from the 5V DC backplane line, the card puts minimal load on the chassis power supply. This thermal efficiency prevents heat accumulation inside sealed control enclosures, extending the lifespan of adjacent modules.
Streamlined Single-Common Wiring: The 16-points-per-common configuration maps all incoming signal return paths to a single terminal block location. This wiring layout accelerates initial cabinet assembly, simplifies loop checking, and cuts down on wire-routing complexity.
Heavy-Duty Transient Filtering: The input circuits handle a wide operating envelope (170 to 265V AC) and incorporate internal filtering to buffer against line sags, harmonic distortions, and electrical noise from nearby high-power motor drives.

FAQs

Is this 1746-IM16 input module a brand new factory item or a surplus pull?
We sell the 1746-IM16 module strictly in 100% brand new, original, authentic factory condition. It ships in its original unopened packaging to verify pristine electronic integrity and total field reliability.
Does this module require a separate external power source to run its internal circuits?
No. The 1746-IM16 draws its internal logic operating power directly from the SLC 500 chassis backplane bus, utilizing only 0.085 Amps at 5V DC. You only bring the 200/240V AC field lines to the front terminal block to energize the individual input points.
Can I use this module to track 120V AC signal lines?
No. The 1746-IM16 has an operating voltage threshold requiring 170 to 265V AC to register a logic high ("ON" state). If your system uses 120V AC field loops, you must use a dedicated 120V AC input card (such as the 1746-IA16) to ensure proper signal detection.
What precautions should I take regarding the terminal block common path?
Because all 16 channels share a single common, you must ensure that all field inputs routed to this module originate from the same electrical phase and voltage source. Mixing different AC phases across this terminal block will cause short circuits and trip upstream circuit breakers.
