Allen-Bradley 1794-IC16 16-Channel Sinking Input Module

Product Overview

The Allen-Bradley 1794-IC16 is a Flex I/O digital input module. It provides 16 nonisolated sinking inputs. Each input works with 30V DC to 60V DC. The module supports a maximum on-state current of 7.0mA at 60V DC. It consumes 6.4W at maximum load. This module belongs to the Rockwell Automation Flex I/O series. It enhances the capacity of an existing system. The compact design measures 46 x 94 x 53 mm. It supports both screw and DIN rail mounting. The module includes 16 indicator lights for status. These indicators are logic driven for easy diagnostics. The 1794-IC16 also features a high isolation voltage of 1900V DC. This ensures robust performance in harsh environments.

Application Scenarios

This module suits industrial automation and process control. It is ideal for monitoring discrete sensors. Applications include limit switches, push buttons, and proximity sensors. The 16 inputs allow multiple device connections. It works with PLC and PAC systems from Allen-Bradley. Use it with the 1794-TB3 terminal base for wiring. The module expands I/O capacity in existing Flex I/O racks. It is common in manufacturing, packaging, and material handling. The rugged design suits factory floor environments. You can mount it on a DIN rail inside an enclosure.

Installation & Maintenance Guide

Install the 1794-IC16 module onto a compatible terminal base like the 1794-TB3. First, attach the terminal base to a DIN rail. Hook the base over the top of the rail. Align the module with the FlexBus connector. Slide the module until it locks into place. Tighten the screws to secure the connection. Wire the inputs following the terminal assignments. Use proper wire sizes from 0.34 to 3.3 mm². Ensure polarity matches the sinking input configuration. The module supports daisy-chaining via the terminal base. For maintenance, check the indicator lights for faults. Keep the module clean and dry. Avoid exposure to excessive vibration. Configure input filter time as needed using software. We recommend using a surge protector for power stability.
