Adjustable Delay Timer Relay Details

Technical parameters include rated voltage, contact working current, contact type and quantity, delay range, accuracy, adaptation to ambient temperature, mechanical life and electrical life, etc. Now take SJ23 series air-type time relay as an example, its technical parameters are as follows:

1) Rated control capacity: AC300VA, DC60W (30W delay head assembly).

2) The rated voltage level of the relay: AC380V, 220V, DC220V, 110V.

3) The rated voltage of the coil: AC110V, 220V and 380V.

4) The maximum working current of the contact: 0.79A at AC380V, 0.27A (momentary) and 0.14A (delay) at DC220V.

5) Delay repeat error: ≤9%.

6) Hot-state pull-in voltage: no more than 85% of the rated voltage of the relay. When the voltage drops from the rated value to 10% of the rated value in the cold state, it can be reliably released, and it can be reliably released after 110% of the rated voltage is relayed.

7) The mechanical life is not less than 1 million times, and the electrical life is 1 million times (the DC life of the delay head assembly is 500,000 times).
