The PSR-FSP is compatible with “test pulses” that occur on safe PLC/DCS outputs. Inrush requirement is limited for safe PLC/DCS output compatibility, and it has a built-in fuse for the safe output contact. Just 17.5mm wide, the relay features a normally open (NO) redundant safety output and a normally closed status contact that can be externally connected. The maximum switched current of the NO contact is 5A. The device also has an externally accessible 5x20mm standard fuse to protect the load contact.
