1746-IA16 Advantages
The Allen‑Bradley 1746‑IA16 Digital AC Input Module stands out from comparable digital input modules in several key areas.
16‑channel high‑density 120V AC input design. The Allen‑Bradley 1746‑IA16 Digital AC Input Module provides sixteen independent 120V AC input channels within one module unit, suitable for industrial sites adopting AC discrete signal loops and saving SLC‑500 PLC rack slot space.
Optical galvanic isolation protection. The Allen‑Bradley 1746‑IA16 Digital AC Input Module adopts 1500V opto‑coupler isolation to separate 120V AC field circuits from PLC internal logic, preventing surge and noise interference from damaging SLC‑500 backplane components.
Hardware‑based noise‑filtering function. The Allen‑Bradley 1746‑IA16 Digital AC Input Module integrates on‑board filtering components to suppress high‑frequency electromagnetic noise generated by on‑site motors and variable‑frequency drives and avoid false‑trigger events.
Individual channel status LED indicators. The Allen‑Bradley 1746‑IA16 Digital AC Input Module is equipped with per‑channel LED status lights for quick on‑site fault diagnosis of field switch and sensor signals.
Native Allen‑Bradley 1746 SLC‑500 integration. As a factory‑original Allen‑Bradley 1746 series component, the Allen‑Bradley 1746‑IA16 Digital AC Input Module plugs directly into standard SLC‑500 chassis slots without additional signal‑conversion adapters.
Practical screw‑terminal field‑wiring layout. The Allen‑Bradley 1746‑IA16 Digital AC Input Module uses clearly marked screw‑type terminals, simplifying 120V AC field wiring, fault‑checking work and fast spare‑module replacement to reduce plant maintenance downtime.
1746-IA16 Applications
