The 1SVR500020R0000, part of the CT-D timer range, is a multifunction electronic time relay designed for flexible control applications. It provides seven distinct timing functions, including ON-delay and OFF-delay, across seven selectable time ranges from 0.05 seconds to 100 hours. The device operates with a wide rated control supply voltage of 24-48 V DC or 24-240 V AC. It is equipped with a single changeover (SPDT) output contact rated at 250 V / 6 A and uses a voltage-related, non-floating control input for triggering. This relay's versatility and compact design make it suitable for a variety of industrial automation and control systems.
