Features

• IEC 61508, EN 61511. PSR Mini PC20 Optocouplers. The PSR Mini PC20 Optocoupler is a coupling relay that can be used for power adaptation and electrical isolation in high and low-demand applications up to SIL 3. When using this module, circuits are interrupted in a safety-oriented manner. The PC20 safety relay has an interface for the TBUS DIN rail connector via which the diagnostic supply voltage can be routed. Used in applications up to SIL 3 according to IEC 61508 ; EN61511 Used for safety-related switching off 12.5mm housing width Approved for Class l, Zone 2 applications Integrated DCS test pulse filter Low inrush current 2 internal 5AT fuses, TBUS connection 1 undelayed enabling current path 1 undelayed confirmation current path 1 digital signal output Option of screw or spring-cage terminal blocks for plug-in
