ELKO EP CRM-181 Single-Function Time Relays

ELKO EP CRM-181 Single-Function Time Relays feature an output contact of 1x changeover (CO) / single-pole, double-throw (SPDT) 16A. These relays are designed for DIN-rail mounting per EN 60715 and are available in four types: ZR, ZN, BL, and OD. The devices offer 10 time ranges, spanning 0.1 seconds to 100 hours. A multifunction red LED flashes or shines depending on the operating status, and all functions initiated by the supply voltage can use the control input to inhibit or pause the ongoing delay. ELKO EP CRM-181 Single-Function Time Relays use A1-A2 supply terminals and operate from a 12V to 240V universal AC/DC supply voltage. The CRM-181 series is suitable for applications where there is a clear function requirement in advance and for universal use in automation, control and regulation, and in-house installations.
