VL-TR-RT8(S)-2TA(2TB) — Dual-Loop Staggered Delay Time Relay
The time relay is a programmable time control device designed to manage power-on and power-off delay operations in electrical circuits. It can work with other electrical equipment to separate control loops and enable staggered operation of terminal equipment.
It is suitable for industrial equipment, lighting systems, manufacturing automation, and other applications requiring precise time control.
The series supports a wide working voltage range of AC/DC 24–240V, LED status indication, adjustable delay time, S control or trigger functions, and optional digital display or knob types. With a compact 18mm design and standard 35mm DIN rail installation, it is easy to install in distribution panels and control cabinets.
