Allen-Bradley 1756-IV16C01FRev3.2 DC Input Module

The Allen-Bradley 1756-IV16C01F Rev 3.2 is a 16‑point DC input module for ControlLogix backplanes that provides two isolated 8‑point input groups for reliable 24 VDC sensing in industrial automation. Each channel accepts 10–30 V DC with a nominal 24 V, presenting a 3.2 kΩ input impedance at 30 V DC and drawing minimal backplane current, with a total backplane power of 0.61 W and a maximum module power dissipation of 5.41 W at 60 °C. The module supports two timing paths: Group 1 offers a 280 μs nominal off‑to‑on delay (max 1 ms) with a user‑selectable input filter of 0/1/2 ms, while Group 2 offers a 540 μs nominal on‑to‑off delay (max 2 ms) with a filter range of 0/1/2/9/18 ms, enabling debounce and noise filtering across the banks. It provides 250 V continuous isolation between input circuits and the backplane and uses the removable 1756‑TBNH terminal housing for field connections. Typical applications include reading 24 VDC sensors, limits, and interlocks in ControlLogix automation systems.
