Olide-120B Automatic Swing Door Opener Controller

• Microcomputer controller, more intelligent -- several sets of transistors are added inside the controller, and a set of protection switches can stabilize the voltage;

• No need for transformer, it is already built into the controller and can be used directly with 110-220V AC voltage;

• Multifunction port, can connect with motion sensor, card reader, electric strike and push buttons, etc.;

PS: please leave a note of your controller model when you place order; Olide-120B and Olide-120BS have different controllers.
