XINJI XINCHANGJIANG Delay intermediate relay
purpose
The JZS-7G series static adjustable delay terminal intermediate
relay is used in various protection and automatic control circuits
for DC or AC operation as an auxiliary relay to increase the number
and capacity of contacts. The power on delay or power-off delay
time can be freely adjusted as needed.
Performance
This series of products is a static energy storage delay type
intermediate relay, which stores energy in a capacitor at the
moment of power on. The relay controls the disconnection or action
of the intermediate relay through a digital circuit according to
user settings, thereby achieving the purpose of delay. Has the
following characteristics:
1. Adopting high-performance sealed relays. Moisture proof,
dust-proof, continuous wiring, high reliability.
2. After the relay is activated, there is a light indicator and a
power indicator.
3. The electrical and mechanical lifespan of relays is long.
4. Large contact capacity and low contact resistance.
5. The insulation withstand voltage level is high.
technical conditions

Insulation resistance: Use a 1000V megohmmeter to measure the
insulation resistance between each lead terminal and the housing
locking screw, which should not be less than 10MQ.
Insulation withstand voltage: Each lead terminal can withstand
2000V of the power frequency with the locking screw of the shell,
and the contacts in the same group can withstand 1000V of the power
frequency for one minute,
No breakdown.
