Galvanic isolation device GA4-4
The device with 4 or 2 inputs/outputs is used for providing galvanic isolation between different devices (e.g. between transmitter RT4-5se and control panel) to increase reliability of security system's performance. The outputs of control panel (e.g. PGM, Bell etc.) should be connected to the device inputs (Ix), outputs (Ox) - to the corresponding zones of transmitter. 12V DC power supply is connected to the terminals "+" and "-".
The device is made as a board; therefore it is mounted in a box. The dimensions of the device are: 50x25mm.
