Usage

JZ- series intermediate relays are composed of integrated circuit principle and have good vibration resistance. They are suitable for various power relays and automatic control devices to increase the contact capacity and number of protection and control circuits.

Main performance

Conventional electromagnetic type intermediate relays of 100V and 220V use very thin wires and many turns, resulting in easy line break and low reliability. Operation time and return time. This series of intermediate relays adopt static electronic control circuits to control the conduction or turn-off of multiple sealed entrances at the same time.It has the following properties and characteristics:
1. Adopt high performance sealed relay to protect against moisture and dust.Continuous line, high reliability..
2. Accurate operating voltage, high return coefficient, no jitter.Low power consumption, multiple features simultaneous action or return (100% controllability) •
3. Light indicator and power indicator are provided after relay operation.
4. Long electrical and mechanical life of relays.
5. High insulation resistance level.The contact capacity is large and the contact resistance is small.
6, good anti-interference characteristics, can be used in strong interference or power supply voltage quality is very poor.
