Zhiguang Industrial Zone, Liu Town, Yueqing, Zhejiang, China
The integrated relay is highly reliable, resistant to vibration and has high delay accuracy, making it suitable for crane control panels.
Behind the high precision is a small relay: for the core component, the large-capacity relay copper coil carries large current and has strong conductivity.
Integrated device installation form: integrated, bottom plate installation, simple to set up, suitable for high-rise buildings and factory workshops.
The NDS18 time relay is the improved product of JJS27A and JS27A. It has the advantages of high reliability, long service life, anti-pollution, vibration resistance, high delay precision and convenient setting. In particular to a crane control screen.
NDS18 series time relay is suitable for AC 50Hz, working voltage 380V and below or DC 2220V or below delay control circuit. Suction delay release delay according to predetermined time plays the effect of timing control.
Relay is divided according to structure:without intermediate relay and intermediate relay; Divided according to the delay type: Suction delay and delay release;According to the control power supply and power supply voltage category, there are current type and DC type.

Directions for use
1, release delay product: 2, 5 terminal connected to the control switch, do not input voltage or ground.
2. Suction delay products: 2, 5 terminals connected to the controlled contactor open auxiliary contact.
3. The 3 and 4 output ends of the product are solid state electronic switches, so it is not possible to measure their on-off performance with the regional ohm file of the multimeter
