VL-TR-RT8(S)-D — Capacitor-Powered Instant-On / Delay-Off Relay
This time delay relay provides instantaneous power-on and delayed power-off control, allowing reliable operation in systems where control signals must be delayed after shutdown. It is ideal for emergency lighting, instrumentation control, motor startup, and other similar applications.
The relay supports a wide working voltage range (AC/DC 24–240V) and operates without an auxiliary power supply, relying on an internal energy storage capacitor to function after power-off. Adjustable delay options include rotary type (0.1–10 minutes) and digital display type (0.1–999 seconds). Its compact 18mm width design supports standard 35mm DIN rail installation, making it easy to integrate into control panels and distribution cabinets.
