Input Module Allen-Bradley 1794-IV16 - 16 Sourcing Inputs

Product Overview

The 1794-IV16 is an input module from Allen-Bradley. It belongs to the Flex I/O series. This module provides 16 nonisolated sourcing inputs. It operates at a nominal 24V DC. The on-state voltage ranges from 10V to 31.2V DC. The minimum on-state current is 2.0 mA. Typical current at 24V DC is 8.0 mA. Maximum current is 11.0 mA. Input impedance is 4.7 kΩ. Power dissipation reaches 5.7 W at 31.2V DC. These features ensure precise signal detection.

Application Scenarios

This module is ideal for factory automation. It monitors sensors and switches. Use it in PLC systems for discrete input acquisition. It works in packaging, material handling, and machine control. The wide voltage range suits various industrial environments. It integrates easily with other Flex I/O components.

Technical Specifications
