Remote Control System with Status Restore Function

We recommend this DC power no/nc contact memory function RC system (S1MU-DC06/09/12/24 & C-2). This remote control switch operates in 4 kinds of voltages, including 6V, 9V, 12V and 24V. It can remote control lights, motors, fans, electrically operated doors/locks/windows/blinds/cars or other appliances actuated by voltage ac 110~240V or DC 0~28V. Its transmission distance is 100m. There are 4 working modes in it. So you can switch working mode by connect and disconnect jumper. With function of memory, if the power is cut off, the relay will return automatically to the previous status after the power is restored.

We’d like to show the wiring and controlling of ac, dc lamps.

The contact of relay of each receiver is normally open/ closed. So you need to wire ac lamp or dc lamp to normally open contact B&C and supply AC 220V power or dc power to lamp.

Operation:

Setting control mode Toggle: Only connect Jumper-2.

Control mode Toggle: Press -> On; Press again -> Off.

 

Setting control mode Momentary: Only connect Jumper-1.

Control mode Momentary: Press and hold -> On; Release -> Off.

 

Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.

Control mode Latched: Press -> On, another relay Off; Press another button -> Off.

Normally Open and Closed Remote Controller for Contactor

Someone would like a remote control to switch on and off his lamp via controlling a contactor. He drew a picture to illustrate his idea. Maybe it is not so convenient to him to remote control lamp directly, so he choose to control his lamp via a contactor.

We recommend him a 1 channel AC remote switch with memory function (S1MU-AC220+C-2). This 1 channel ac rf memory remote controller operates in toggle, momentary and latched control mode (set the mode as you like freely). With function of memory, if the power is cut off, the relay will return automatically to the previous status after the power is restored. It is great for hard to reach lights or other electrical devices, remote distance up to 100m (theoretically). It is applied to control lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with voltage AC 110~240V or DC 0~28V.

According his requirement, we have this following diagram. Initial state: A, B = Normally Closed; B, C = Normally Open. Wire contactor to normally open contact B&C terminals. And Wire a lamp to contactor and install a switch for lamp (See the original picture).

circuit

There are 3 working mode of remote control. They are toggle, momentary and latched modes. We suggest that he should set latched mode because this remote works with a 2-button transmitter.

Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.

Control mode Latched: Press -> On, another relay Off; Press another button -> Off.

Press button 1: Turn on the contactor to turn on lamp (connect B and C, disconnect A and B)

Press button 2: Turn off the contactor to turn off lamp(disconnect B and C, connect A and B)
