The Siemens 505-4232A Input Module is a 32‑point digital input card for the TI505 PLC, featuring floating inputs and four eight‑input groups. It accepts AC sensor signals in the 79–132 VAC range, with eight inputs sharing a common and built‑in enhanced noise filtering for industrial environments. The module draws about 2 W from the base, with ON currents specified from 4 to 15 mA and OFF current up to 1.5 mA; typical response delay is 6–30 ms, and it operates at 47–63 Hz. Designed as a single‑wide addition to a TI505 base, it expands the controller's digital inputs to 32 points in a compact module.
