Use
JY series integrated circuit voltage relay (hereinafter referred to as "the product") for motor, transformer and transmission line overload and short-circuit protection device as a starting element. This product for the static type of integrated circuit relay, high precision, low power consumption, short action time, return coefficient is high, the setting is intuitive, convenient, it overcomes the original type electromagnetic relay contacts are easily jitter, noise larger, action of return coefficient is difficult to adjust and transport action value liable to change the disadvantages of value of. The products are divided into three series: JY-10, JY-20, JY-30, DJ-100, DY-20C, can replace DY-30electromagnetic relay.
Model
Note: JY - 10, 20, 30 series of current relays and other various types of factory JY - 1A, 1b, 1C, JY8 - 10, 20, 30 series is belongs to products of the same type.
