4-Channel RF Receiver, 11~24 VAC/VDC, 433.92MHz*

The SK-910R4-4Q are wireless receiver meets the growing demand for multi-channel receivers with multiple and independently controlled output modes. RF receivers can be used to control a variety of home automation devices such as garage door openers, lights, motorized gates, lifts, or other devices remotely. These receivers are compatible with both fixed code and code hopping transmitters. Code hopping transmitters, such as SECO-LARM CODEBUMP transmitters, change codes every time transmitter sends a signal for extra security.
