SIRIUS Coupling Technology

For the purposes of electrical isolation, amplification and signal matching, coupling relays and transformers are required between the control system and the peripherals. Coupling relays are used for digital signals and transformers are used for all analog signals, whereby the basic application is the same.

Various criteria apply when selecting products. The device should be compact as well as easy to connect on one level. Whatever your requirements, Siemens has an optimized product to meet your needs.

Applications

Electrical isolation

EMC and overvoltage protection

Contact multiplication

Current amplification

Voltage conversion (e.g 24V - 230V)

Level conversion of analog signals
