Wireless Relay module
The “Wireless Relay Interface module” pairs with a Battery-free Wireless Button. On pressing the button, the module closes an relay contact for a time span of 1 to 9 seconds. The relay contact is a potential free, mechanical contact.
Note: This interface is only compatible with the H0736* models Battery-free Wireless Buttons.
The Relay Interface has a USB C connector for 5 V power input. It is suitable for a USB power supply or powerbank. The interface does not use the USB port for control or programming.
The Relay Interface pairs with a single wireless button. A simple procedure allows you to perform this pairing step. The Relay Interface will only respond to button presses of the button it is paired with. Multiple Relay Interfaces may be paired to a single wireless button, but a single Relay Interface cannot be paired to multiple buttons.
A rotary switch allows you to set the duration that the relay stays actuated, after receiving a signal from a wireless button. The delay is in seconds, and it can be set from 1 to 9 seconds.
Setting the rotary switch to 0 (zero) keeps the relay actuated until the wireless button is pressed another time. That is, a first press makes the contact until a second press breaks the contact.
The Relay Interface module can be mounted on a carrier (or base plate of an enclosure) by using the four 3.2 mm mounting holes, or using double-sided foam tape.
