PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-IV16 is a 16-point digital input module within the FLEX I/O series. It provides nonisolated sourcing inputs designed for 24V DC nominal industrial automation circuits. Each channel accepts incoming voltage signals ranging from 10V DC up to 31.2V DC. The hardware monitors field devices including push buttons, limit switches, and presence sensors.
This input module operates with a nominal on-state current of 8.0 mA at 24V DC. Minimum on-state current is rated at 2.0 mA, with a maximum threshold of 11.0 mA. Input impedance is rated at 4.7 kΩ maximum to optimize digital signal processing. The module dissipates up to 5.7 W of power under full operating load at 31.2V DC.
