Introduction:
- Our DH48S-S is a cyclic time delay relay that can turn the load on and off periodically according to the time you set. For example, if you set T2 to 5 seconds, T1 to 2 seconds, and the load is an LED light, the LED light will be on for 5 seconds, off for 2 seconds, and then repeat all the time. See the timing diagram below:
- Different from our multi-function time delay relay, it does not need an external signal, once it is powered on, it starts to work.
- It has two models, namely DH48S-S-1Z and DH48S-S-2Z. DH48S-S-1Z has one SPDT contact with pause and reset function, but DH48S-S-2Z has two SPDT contacts only.
- The programmable time delay relay off and on time setting range is 0.1 seconds to 99 hours. Once the time is set, the timer will cycle the load on and off.
- The output contact capacity is 5 amps@250 VAC, it can operate a maximum 800 W resistive load directly. If you want to expand its capacity, please try to use it with our AC contactor or solid state relay.
- Applications for this product include ice machines or other equipment that needs to be turned on or off periodically.
