DZ-30B,DZ-30BG series intermediate relayDetailed product description：

1. Application scope
The DZ-30B (DZ-30BG) series intermediate relay is used in various protection and automatic control circuits for DC operation, as an auxiliary relay to increase the number and capacity of contacts.
DZ-30BG is an improved version of DZ-30B. This relay overcomes the 0.06-0.07 enameled wire used in the original DZ-30B relay. The occurrence of wire breakage during long-term transportation has improved reliability. The remaining internal wiring, external dimensions, wiring terminals, and usage functions remain unchanged.

2. Main technical parameters
Rated voltage: DC 220V, 110V, 48V, 24V, 12V.
Action value: rated voltage value of 30-70%.
Return value: not less than 5% of the rated value.
Action time: At rated voltage, the action time shall not exceed 45ms.
Return time: no more than 60ms
Power consumption: not exceeding 7W.
Contact capacity: In a DC inductive load circuit with a voltage not exceeding 250V, a current not exceeding 5A, and a time constant of 5 ± 0.75ms, the output contact of the product has a breaking capacity of 50W. Under the specified load conditions, the output contact of the product can reliably operate and return 5 × 104 times. The long-term allowable current for the output contact is 5A.
