Compact Relays Serve As Safety Devices

Well-suited for emergency stop, guard door monitoring, two-hand operation, and other safety-related applications, the PSR series relays pack in a ME 22.5-mm housing two to eight normally-open (NO) release current paths and one normally-closed (NC) signaling current path. The safety circuit is controlled with one or two channels, with cross circuit detection for safety category 4. All field connections are pluggable and coded, easing wiring. Using the appropriate force-guided relay expansion modules, the safe connection of up to five additional NO release paths and two NC signaling paths is possible. PHOENIX CONTACT INC., Harrisburg, PA.
