Siemens 505-4916A Relay Output Module

Siemens PPX:505-4916-A is a 16-point digital relay output module for the TI505 PLC, delivering sixteen floating Form‑A relay contacts in a single-wide, backplane-mounted package. It supports AC or DC loads with a rated operating range around 24–230 VAC or 6–24 VDC, and it carries a non‑latching, unprotected output configuration suitable for driving relays, solenoids, or other loads from automation panels or machine controls. Key electrical specs include a total relay contact resistance of about 250 milliohms, a maximum transient overload of 5 A for 1 ms, a maximum relay repetition rate of 6 Hz, and a power draw of roughly 2.5 W from the base. The module provides 16 Form‑A outputs that are isolated from the TI505 backplane, enabling straightforward interfacing to higher‑voltage or higher‑current load circuits without affecting the controller’s internal operation.Applications typically involve interposing devices, relay‑driven actuators, and sequence control in industrial automation environments that utilize the TI505 platform.
