Description
Product Overview
The Allen-Bradley 1746-IN16 is a 16-channel digital AC/DC sinking input module for the SLC 500 series. It interfaces discrete field signals at 24VAC/VDC over a 10–30V range, occupying a single chassis slot. The module weighs approximately 0.35 kg (0.77 lb).

Engineering Advantages
Sixteen sinking channels fit into a single slot, maximizing rack density. Each channel carries a dedicated LED indicator for at-a-glance field signal verification and troubleshooting. The 1 mA off-state current prevents false triggering from line leakage. Faster 15 ms response on DC signals suits time-critical interlocks. At roughly 0.35 kg, the module adds minimal weight to the chassis. It mounts directly to any 1746 local or expansion chassis bus connector.
Technical FAQs
Q1: How many channels and what voltage does it accept?
A1: 16 sinking channels at 24VAC/VDC nominal, operating over 10–30V.
Q2: What is the signal delay for AC versus DC?
A2: 15 ms for DC signals and 25 ms for AC signals on both transitions.
Q3: How much backplane current does it draw?
A3: 0.085 A at 5V DC, with 6 W total power consumption.
