Safety relays with reinforced insulation

20 November 2002 Switches, Relays & Keypads

The new PSR safety relay family from Phoenix Contact provides high standards for monitoring emergency cut-out and safety door power circuits and two-hand controls. All connections are pluggable and coded. They give users high wiring convenience and safety during servicing. The modules offer reinforced insulation between input and output and between the release and signalling circuits in their compact and space-saving design. One- or two-channel safety circuit control is possible with or without short-circuit detection. These modules meet the requirements of EN 954-1 category 4 and can be used for stop category 0/1 as defined by EN 60204.
