Allen-Bradley 1791-16AC

Product Overview

The Allen-Bradley 1791-16AC is a compact block I/O module offering 16 discrete 120V AC input channels. Designed for use in distributed I/O systems, this module simplifies field wiring and is ideal for harsh environments with its rugged, IP67-rated housing. It supports sink input connections and integrates seamlessly into Rockwell Automation architectures.

Key Highlights

• Input Channels: 16 discrete AC inputs

• Voltage: 120V AC nominal

• Input Type: Sink (common grounded return)

• Form Factor: Compact block I/O

• Wiring: Prewired connection points

• Enclosure: Fully encapsulated, IP67 rated

• Mounting: Panel or machine-mounted (direct wiring)

Detailed Specifications

• Part Number: 1791-16AC

• Voltage Range: 79–132V AC

• Frequency: 47–63 Hz

• Input Delay: Filtering for signal stability

• Current Draw: Approx. 10 mA per input

• Dimensions (H x W x D): Approx. 110 mm x 190 mm x 50 mm

• Operating Temp: 0°C to 60°C

• Certifications: UL, CSA, CE

• Protection Class: IP67 (dust-tight and water-resistant)

Common Uses

• Machine-level I/O in industrial automation

• Distributed I/O architecture for PLC systems

• Harsh environments requiring IP67 protection

• OEM equipment and factory installations

• Conveyor, packaging, and material handling control

Why It Stands Out

• High-density input in a rugged form factor

• Reduces control cabinet space and wiring complexity

• IP67 rating ensures durability in washdown and dusty areas

• Simple plug-and-play installation for distributed systems

• Backed by Allen-Bradley reliability for industrial I/O
