Digital time relay
This series of digital time relay adopts electronic control circuit to control multiple fully sealed relays to be turned on or off at the same time. And has the following performance and characteristics:
3.1 Adopt high-performance sealed relay, moisture-proof, dust-proof, continuous line, high reliability.
3.2 The principle of integrated circuit is used to overcome the difficulty of adjusting the contacts of electromagnetic relays.
The problem of low delay accuracy, good vibration resistance reduces maintenance workload, and reduces labor intensity to a certain extent.
3.3 After the relay is activated, there is an indicator light.
3.4 Relays have a long electrical and mechanical life.
3.5 High insulation withstand voltage level, large contact capacity, low contact resistance.
It can be installed on the guide rail or fixedly, which greatly facilitates the selection and wiring of the customer.
3.1 Environmental reference conditions 3.2 Normal use conditions
Ambient temperature: 20 ° C soil 2 ° C ambient temperature: -25 ° C ~ + 50C
Relative humidity: 45% ~ 75% Environmental relative humidity: not more than 90%
Atmospheric pressure: 80Kpa ~ 106Kpa Atmospheric pressure: 80Kpa ~ 1 10Kpa
Extreme temperature during storage and transportation: -25 ° C ~ + 75C
Altitude of use place: no higher than 3000 meters
The surrounding medium of the use environment has no explosive dangerous goods; it does not contain corrosive gases; the concentration of conductive dust should not reduce the insulation level below the allowable value.
3.2 Relay ratings
Rated voltage: 6V, 12V, 24V, 48V, 110V, 220V AC / DC, 380VAC.
3.3 The contact capacity can be cut off 5A in the AC circuit whose voltage is not greater than 250V and the power factor COSφ is 1.0.
DC: Connect DC220V, 5A; disconnect DC220V, τ = 5mS, 50W load.
3.4 Power consumption
Not more than 5W at rated voltage.
3.5 Insulation resistance
Use a 1000V shake meter to measure the insulation resistance between each lead-out terminal and the housing locking screw is not less than 10MQ.
