Phoenix Contact PSRcompact Safety Relays

Phoenix Contact PSRcompact Safety Relays perform typical safety functions while occupying less DIN-rail space than traditional 22.5mm safety relays. Phoenix Contact PSRcompact relays, which feature a minimum width of 12.5mm, are wider than the PSRmini (6mm) relays. The MC32 supports input voltages from 24VAC/DC to 230VAC/DC. The MC55 is a versatile safety relay that supports most safety relay applications. The MC73 features delayable contacts up to 300s. The MC80 and MC82 are contact extensions. The MC92 supports two-hand control in accordance with ISO 13851 Type IIIC.
