描述

CRM-82TO/UNI is a true off-delay time relay that initiates timing after power supply disconnection, providing reliable delayed switching control in critical applications. The relay features dual time functions (delayed return after supply disconnection and delayed start) adjustable via rotary switch and potentiometer, with a time range of 0.1 s to 10 min and exceptional repeat accuracy of 0.2% set value stability. It operates across a wide voltage range of AC/DC 12–240 V (AC 50–60 Hz) with supply voltage tolerance of -15% to +10%, and includes green LED supply indication and red LED output status indication. The relay provides 2 changeover contacts (DPDT, AgNi/Silver Alloy) rated at 8 A/AC1 with a breaking capacity of 2000 VA/AC1 and 192 W/DC, ensuring robust electrical performance. Common applications include emergency lighting systems, emergency respirators, and controlled door protection during power failures, where delayed switching is essential for safety and system continuity.
