Penerangan
Product Overview
The Allen-Bradley 1794-IV16 is a 16-channel DC Input Module for the Flex I/O series. It provides 16 nonisolated sourcing inputs operating at 24V DC nominal with a 10-31.2V DC range. The module delivers 8mA nominal on-state current and 4.7kΩ maximum input impedance for reliable signal acquisition in industrial control systems.
Core Functionality
The 1794-IV16 accepts sourcing input signals from field devices such as proximity sensors, switches, and photoelectric sensors. It requires a minimum on-state current of 2.0mA and maintains predictable off-state behavior with 5V DC maximum and 1.5mA minimum current. The module dissipates up to 5.7W at 31.2V DC, ensuring safe operation within Flex I/O racks.

Installation Guide
Mount the 1794-IV16 on the Flex I/O terminal base. Connect 24V DC sourcing field devices to the input terminals. Verify on-state voltage remains between 10V and 31.2V DC. Ensure minimum on-state current of 2.0mA for reliable signal detection. Check off-state voltage does not exceed 5V DC to prevent false triggering.
Engineering Advantages
This module delivers 16 sourcing inputs in a compact Flex I/O form factor. The 4.7kΩ input impedance minimizes field circuit loading. Wide on-state voltage range (10-31.2V DC) accommodates supply variations. Low 5.7W maximum power dissipation reduces thermal load. Predictable off-state characteristics (5V/1.5mA) ensure noise immunity.
