Phoenix Contact has added four new part numbers to their safety relay range. One version has three redundant normally open (NO) contacts and one normally closed (NC) status contact. Another version has two redundant NO safety contacts and one NC status contact. Both are available in either spring or screw connection.
These new relays can be reset with either a monitored manual or automatic reset. Previous relays required you to choose which type of reset (monitored manual or automatic) is required. The PSR-ESAM relays eliminate the need to understand the reset circuit, simplifying your selection.
