    Product RF433 MHz 4-channel relay with remote control - makes a good impression, high-quality workmanship, 2 remote controls delivered instead of one. The device is fully functional, operated on 12 V DC. It fulfills its purpose, it has only this small shortcoming - in reality, only the enclosed controllers can be used, the attempt to pair other types is complicated, the contacts on the relay must be measured and there is still a risk of collision of individual channels. Maybe some 4 channel driver 1-4 could be used. Overall satisfaction.

    This is a solid and reliable device with four relays which are controlled (activated and deactivated) by the four corresponding buttons (A, B, C & D) on the remote fob. Each of the four relays has a normally open (NO) contact and a normally closed (NC) contact. While “activated”, the normally open contact is closed and the normally closed contact is open. On the main device, the contacts for the four relays are labeled “A, B & C”. The “B” contact is the Common (COM) contact. The “A” contact is the Normally Open (NO) contact and the “C” contact is the Normally Closed (NC) contact. I have attached a picture where I have labeled all of the contacts. There are three operational modes. I have attached a picture that has the three different jumper pin configurations identified. JOG (momentary) MODE is in effect when the jumper cap is removed. Each relay is activated only while the corresponding remote button (A, B, C or D) is pushed and held and is deactivated when the button is released. SELF-LOCK (latching) MODE is in effect when the jumper cap is used to link the two jumper pins on the left (as viewed from the back). In this mode, each relay is activated when the corresponding remote button (A, B, C or D) is pushed and released. Pushing and releasing the button a second time deactivates the relay. Any combination of the four relays can be active at the same time. INTER-LOCK MODE is in effect when the jumper cap is used to link the two jumper pins on the right (as viewed from the back). In this mode, only one relay can be active at a time. Pushing a button on the remote activates the corresponding relay and deactivates any previously activated relay. For example, if you press and release the “A” button, the “A” relay is activated. If you then push the “C” button, the “C” relay is activated and the “A” relay is deactivated.

    This is a great little device. Solid and reliable. This is actually the second one I purchased. I didn’t really need a second one yet but I was really impressed with the first one and I couldn’t resist ordering another one to have on hand for future projects. Check out my other review for my notes on connecting and using this device. I also ordered a second remote and it was very easy to pair it.
