GST Loop Relay Module

P-9903 Loop Relay Module is 24VDC powered. The input and output of loop signal are insulated to ensure transmission of detector signal which enhances interference-resistant ability of the system and prolongs the loop distance. P-9903 is mainly used in applications where strong electromagnetic interference exists or where the loop needs to be extended to longer than 1000m. The relay module consists of a transmitter circuit, a receiver circuit, and an isolated power supply. Optocoupler isolation technology is used between the transmitter and receiver circuit

Installation Mounting dimension is shown in Fig. 2. If the relay is used to resist interference, it should be installed outside the area suffering from the interference. For example, it can be installed inside the FACP. If it’s used to lengthen communication distance, it should be installed where the distance to the FACP is not longer than 1000m. It should be indoor-installed using M4 screws.
