JOSEF delay intermediate relay JZS-7G/45 DC220V principle leading

Description :

　　The JZS-7G series adjustable delay intermediate relay (hereinafter referred to as the electrical appliance) is used in various protection and automatic control circuits to increase the number and capacity of contacts in the protection and control circuits. The power on or power-off delay time can be adjusted as needed.

　　This series of relays has the following characteristics:

　　1. This relay is composed of multiple sealed small relays with low coil voltage, which are moisture-proof, dustproof, continuously wired, and highly reliable. It overcomes the disadvantage of electromagnetic intermediate relays with thin wires that are prone to breakage;

　　2. Low power consumption, low temperature rise, no need for external high-power resistors:

　　3. Relay contacts have large capacity and long working life;

　　4. After the relay is activated, it is displayed by a light-emitting tube for easy on-site observation:

　　5. The delay only needs to be set with the dip switch on the panel, with high delay accuracy and a delay range of 0.02-6s that can be set arbitrarily

　　Technical Requirements

　　1. Rated value: Rated voltage DC/AC48V, 110V, 220V, AC380V:

　　2. Action value: The DC action voltage should not exceed 75% of the rated voltage, and the AC action voltage should not exceed 80% of the rated voltage;

　　3. Action time: no more than 20ms:

　　4. Contact capacity: In DC inductive load circuits with voltage not exceeding 250V, current not exceeding 1A, and time constant of 5ms 0.75ms, the breaking capacity is 50W; in AC circuits with voltage not exceeding 250V, current not exceeding 5A, and power factor of C-0.+0.1, the breaking capacity is 500VA. The output contacts can reliably operate and return 100000 times under the specified load conditions. The long-term allowable current for the output contact is 5A

　　5. Power consumption: not exceeding 5W/5VA at rated voltage
