In addition to UP and Down models, a reversible(Up-Down)counter is also available.
Maximum counting speed of 1000cps, never before attained by a small-size preset counter. Models with memory backup function against power failure available.
Power supply freely selectable within a range of 100 to 240VAC.
Also, power supply for the DC-operated models is selectable within a range of 12 to 48 V.
This product has passed CP certification.
Request A QuoteTechnical 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).
