1756-IB32

The 1756-IB32 input module from Allen Bradley, part of the ControlLogix family, offers robust functionality for various control applications. It supports 32 individual inputs with a configuration that allows for 16 points per group. Operating voltage spans from 10 volts to 31.2 volts DC, catering to a variety of signaling needs. This module has a current draw of 120 milliamps when receiving 5.1 volts and a mere 2 milliamps with 24 volts present.

Power consumption is efficient, with total backplane power measured at 0.66 watts. The maximum power dissipation reaches 6.2 watts when the operating temperature is at 60 degrees Celsius, alongside a thermal dissipation rate of 21.1 BTU/hr at this temperature. The input module features enhanced performance with a maximum off-state voltage capped at 5 volts and an upper limit on off-state current of 2.27 milliamps.

In terms of operational thresholds, the on-state current must be at least 4.8 milliamps, achievable at 10 volts DC, while it may peak at 5.5 milliamps when 31.2 volts DC is supplied. The device can withstand a maximum inrush current of 250 milliamps without issue, allowing for flexible operation in dynamic environments. The input impedance is noted at 5.67 kΩ when running at maximum voltage. This input module is housed in an open-style enclosure, providing ease of access and installation for integration into larger control systems.
