Allen-Bradley 1769-IQ32T 32-Point DC Input Module

Allen-Bradley 1769-IQ32T is a 32-point, 24V DC input module for CompactLogix/Compact I/O systems, designed to accept sink or source wiring in a single-wide form factor. It operates from 20.4 to 26.4 V DC at up to 60 °C ambient, with an input impedance of 5.6 kΩ and isolation between input points and the bus (and between groups) rated at 1200 VAC for 1 second or 1697 V DC for 1 second. Each of the 32 inputs supports an off-state voltage up to 11 V and an on-state voltage at least 19 V, with off-state current ≤ 1.7 mA and on-state current ≥ 2 mA; inrush current is limited to 5 mA. Digital filtering is configurable from 0 to 8 ms (0 s, 100 ms, 500 ms, 1 ms, 2 ms, 4 ms, 8 ms) and input delay from off-to-on is as low as around 0.1 ms (typical ~0.42 ms) while on-to-off delay is around 0.25 ms (typical ~1.0 ms). Power draw is about 170 mA at 5.1 V (internal supply) with heat dissipation up to 4.77 W. The module weighs roughly 0.28 kg (0.61 lb) and measures about 118 mm high, 35 mm wide, and 87 mm deep (H×W×D), making it a compact 32-point 24V DC input solution for field devices such as switches and sensors in CompactLogix installations.
