Schneider Electric – XPSECPE3910P – Preventa XPSEC Safety Relay Expansion Module

The Schneider Electric XPSECPE3910P is a modular safety relay expansion unit from the Preventa XPSEC series. Designed to increase the number of safety contacts in an existing safety relay base, it supports supply voltages from 115 to 230 V AC/DC and mounts on 35 mm DIN-rail. It offers eight additional normally-open (NO) contacts, two normally-closed (NC) contacts, and one solid-state output, effectively enhancing safety circuit capacity up to PL e/Category 4 and SIL 3 levels.
