Allen-Bradley 1746-IA16-SERC 16-Point 120VAC Input Module, Series C

The Allen-Bradley 1746-IA16-SERC is a Series C 16-point AC digital input module designed for dependable signal monitoring in SLC 500 control systems. It provides stable, isolated detection of 120VAC field inputs while integrating seamlessly into any Allen-Bradley 1746 chassis.

Why It Helps
This module improves system reliability by using optical isolation, noise filtering, and surge protection to ensure accurate signal readings from switches, sensors, and other AC devices. Field wiring is streamlined with a removable terminal block, and built-in status LEDs simplify diagnostics and system maintenance.

Key Highlights

• Sixteen 120VAC input channels provide high-density signal monitoring for industrial applications. Each channel includes input filtering to minimize electrical noise and ensure consistent PLC readings.

• Optical isolation helps protect the SLC 500 processor and backplane components from voltage spikes and electrical interference.

• A removable, color-coded terminal block allows easy module replacement without rewiring field connections, reducing downtime during maintenance.

• LED indicators for each input channel offer instant visual confirmation of device status, aiding fast troubleshooting.

• Designed to meet industrial environment requirements through durable construction and built-in surge protection.

Applications
Ideal for machinery control panels, automated equipment, OEM systems, packaging machinery, and any installation requiring reliable 120VAC input monitoring within an SLC 500 architecture. Its robust design supports long-term operational stability in demanding environments.
