Siemens 505-4232A Input Module

Siemens 505-4232A is a 32-channel digital input module for TI505 PLCs that provides 110 VAC inputs in a single-wide slot. It accepts ON voltages between 79 and 132 VAC and OFF voltages from 0 to 20 VAC, with an input current of 4 to 15 mA during ON and up to 1.5 mA leakage when OFF. The module uses floating inputs and an enhanced noise filter to improve EMI rejection, and it draws about 2.0 W from the base backplane. Rated for 47 to 63 Hz operation, it has a through-module delay of 6.0 ms minimum to 30.0 ms maximum. The 32 discrete inputs are intended for direct connection of 110 VAC sensors, switches, and relays to TI505 controllers, delivering a compact, single-wide I/O solution for high‑voltage automation tasks.
