SIRIUS Relays – One Range for Every Application

The portfolio of SIRIUS relays offers all components required for motor feeder applications from a single source. 


Whether you require compact timing or monitoring relays, particularly narrow coupling relays, plug-in relays, low-noise power relays or interface converters – our relay range is the most complete and comprehensive portfolio on the market. 
Convince yourself!

Timing relays are employed wherever simple time-controlled processes are required. Timing relays are also and particularly required in connection with a control. Whether ON or OFF delay relays or relays for switchover from start to delta – SIRIUS timing relays are employed for all delayed switching processes in control, starting, protection and regulation circuits.

SIRIUS Timing Relays

Our comprehensive range of SIRIUS monitoring relays ensures reliable system protection against damage. Current measured values or conclusive diagnostics messages are indicated on the device display. For easy connection to the control, most monitoring relays are also available with IO-Link interface!

SIRIUS Monitoring Relays

When standard controllers with their standard inputs/outputs reach their limits, coupling relays and interface converters come into their own. A wide selection of coupling relays and interface converters is available for the electrical isolation of I/Os and PLC inputs and outputs, signal amplification or reproduction as well as conversion to different voltage levels or signal forms. We offer the appropriate solution for all requirements.

Safety Systems

Safety Systems

The new safety relays facilitate the easy realization of safety functions such as Emergency-Stop or protective door monitoring. Their modular design ensures eased system planning, commissioning and expansion.

Moreover, no programming knowledge is required: The safety relays can be simply parameterized via DIP switches. This ensures the protection of persons, environment and machine – and supports the rapid and easy realization of safe and productive systems.

SIRIUS 3SK Safety Relays

With our SIRIUS 3RK3 Modular Safety System (MSS), you can rely on a universal modular system that enables you to adapt machines and plants in the most flexible and economic way – both for new designs and for retrofits. Because safety functions can be parameterized quickly and easily using the MSS ES software.  Thanks to the consistent modularity, you are also extremely flexible within your applications and save costs since you do not have to utilize more modules than necessary. The SIRIUS 3RK3 Modular Safety System can be applied for safety applications up to SIL 3 according to IEC 62061 and PL e according to ISO 13849-1 respectively.

SIRIUS 3RK3 Modular Safety System

With electronic relay or auxiliary contact enabling circuits as well as with special functions, it provides reliable switch off in hazardous situations and make the efficient configuration of continuous safety chains possible.
