UMA WR-2-RX – Wireless 2-Channel Relay Receiver – 433 MHz – 12 V

UMA WR-2-RX – wireless 2-channel receiver with NO/NC relays
The UMA WR-2-RX is a compact wireless receiver with two independent relays, designed to work with the UMA WR-2-TX dual relay transmitter (available separately). It runs on 12 V DC (not included) and offers a flexible, universal way to switch devices wirelessly – no cabling needed.

With this NO/NC switching solution, products from different segments or manufacturers can easily be integrated at hardware level – ideal where cabling is unwanted or impossible, for example when linking IP cameras, NVR alarm outputs, access control or alarm systems.

Function and application
The WR-2-RX receives signals wirelessly from the WR-2-TX transmitter on 433 MHz. It has 2 separate relays (each max. 2300 W AC) and can be paired with up to 128 transmitters. One transmitter can also control several receivers – limited only by range (up to 300 m in open field).

The receiver supports three modes:

• Momentary: relay active while the transmit command is active
• Latching: a short command toggles the relay
• Timed: a short activation switches the relay on for 1–255 seconds

Configurations such as 1:1, 1:n, n:1 or n:n are possible depending on your application. An English manual is included.
