The telephone connection relay 750340 from ELSO is a versatile accessory for telecommunications, specifically designed for integration into patient call systems. It enables the connection of telephone calls via a potential-free contact, ensuring a reliable link between the telephone line and the call system. The relay is activated by the ringing voltage of a telephone line, which ranges from 0.5 to 40 V AC/DC. With a maximum load of 230 V AC and 6 A, it provides a robust solution for various applications. The adjustable drop-out delay of 0 to 12 seconds allows for flexible adaptation to specific requirements, while the on-time can also be configured via a potentiometer. Installation is straightforward and secure on a DIN rail, making it easier to integrate into existing systems.
