HZB-100,HZS-100 series static intermediate relayDetailed product description：

1. Scope of application

The HZB-100 and HZS-100 series static intermediate relays are used as auxiliary relays in various protection circuits to increase the number of contacts or contact capacity of the protection relay. HZB-100 and HZS-100 are composed of digital circuits and high-quality small relays, which are moisture-proof, continuous, high-precision, sensitive and reliable, have low power consumption, low temperature rise, power on light, light indication after action, and can be installed freely. Overcoming the disadvantages of electromagnetic relays such as easy disconnection and different contact actions. HZB-100 replaces similar products such as DZB-100 and JZB-100. HZS-100 replaces products such as DZS-100 and JZB-100 respectively.

2. Main technical data

The technical data of HZB-100 series intermediate relays are shown in Table 1.

Contact disconnection capacity: 50 watts in a DC inductive load circuit with a voltage not exceeding 200 volts and a current not exceeding 1 ampere (time constant of 5 × 103 seconds); It is 250 volt ampere in an AC circuit. The contact is allowed to pass a current of no more than 5 amps for a long time.

The rated values of HZS-100 series delay intermediate relays are shown in Table 2.

model	Rated value (V)	Rated current value (V)	Maintain the number of windings	Delay method	action value	anti-value
HZS-115	twenty-four forty-eight one hundred and ten two hundred and twenty			Action time ≥ 0.06s	30%~70%Un	≥30%Un
HZS-117
HZS-145				Return time ≥ 0.8s
HZS-127		1.2,4	two	Action time ≥ 0.06s
HZS-136			two

Power consumption: not exceeding 5 watts at rated voltage.  
Contact capacity: In a DC inductive load circuit with a voltage not exceeding 220 volts and a current not exceeding 1 ampere (time constant of 5 × 103 seconds), the breaking capacity is 50W; in an AC circuit, it is 250 volt amperes. The contact is allowed to pass a current of no more than 5 amps for a long time.
The technical data of HZB-100 series intermediate relays are shown in Table 1. Note: HZB-138 has a damping and holding function. HZB-115 is used to maintain the current working voltage.
The rated values of HZS-100 series delay intermediate relays are shown in Table 2. Note: When placing an order, the user should indicate the return time or action time. If there is no indication, our factory will replace the data of the electromagnetic series products.
