Exta Life - 2-channel modular radio receiver ROM-22

The ROM-22 modular radio receiver is the final element of the EXTA LIFE system, enabling independent control of any two devices/circuits. The outputs consist of two relays with changeover contacts (NO/NC) with a maximum load capacity of 10A.

This allows for control of low-voltage circuits (e.g., 12/24 V AC/DC) and high-voltage circuits (230 V AC). The receiver is also suitable for remotely triggering other devices and can be successfully used for providing control signals.

The ROM-22 is also suitable for controlling solenoid valves in heating systems. Bidirectional communication between the receiver and the controller means that the current status of each receiver channel is displayed in the mobile application.

Bidirectional communication also allows for changing selected receiver parameters and remotely assigning transmitters (without access to the receiver). A frame coding algorithm ensures control security.

The receiver, in addition to the controller, can be controlled simultaneously using EXTA LIFE system transmitters. The receiver can accommodate multiple transmitters, enabling independent control from multiple locations.

Configurable wired inputs enhance control functionality. The receiver features remote software updates from the controller. The device is designed for installation in switchboards on a TH35 (DIN) rail.

The detachable antenna allows you to connect an external antenna.
