Three-circuit Time Relay
VL-100А, VL-101А

Three-circuit time relay has instantaneous, passing and finite contacts. Such a kind of device is used with the time excerpts (delays) after giving (VL-100A) and after turning off the supply voltage (VL-101A).

The time relays (VL-100A, VL-101A) are intended for switching of electrical circuits with certain time excerpts, that are beforehand set in the protection devices, emergency control systems and industrial automatic equipment.

• Working temperature: - 40 °С … + 55 °С.
• Unified linkage and connection dimensions for the convenience of the relay mounting and service.
• The mounting with front / back wires connection.
• Step control of the actuation settings with discretization of 1% of the maximum value.
• For visual control and operative change relay actuation unitshave a transparent cover with a possibility of sealing.
• LED indication of the output relay actuation.

Working conditions

Closed housing in areas with a temperate and frigid climate.
Shaking effect:
- in the range of the frequencies of (5-15) Hz with an acceleration of 3 g;
- in the range of frequencies to 60 Hz with an acceleration of 2 g;
- in the range of frequencies to 100 Hz with an acceleration of 1 g;
- repeated blows by duration (2-20) ms with acceleration of 3 g.
Working position in the space – any.
