Safety Relay Expansion PSR-ME40-4NO-2NC-24DC-SC 24V DC 1397653

The Phoenix Contact PSR-ME40-4NO-2NC-24DC-SC-SET35 (Part No. 1397653) is a set of 35 safety relay expansion modules designed to extend the contact capacity of machine safety systems. Used in conjunction with a compatible safety relay base device, these expansion relays provide additional safe output contacts while maintaining safety performance up to Category 3 and Performance Level d (PL d) according to EN ISO 13849. The module features 4 enabling contacts and 2 auxiliary/confirmation contacts, with an adjustable dropout delay ranging from 0.5 to 30 seconds for controlled machine shutdown processes. The compact 22.5 mm-wide housing and plug-in screw terminal blocks simplify installation and maintenance in industrial control panels.
