Overview of applications

The RIF-0 and RIF-1 relay modules are used in particular to safely couple signals between the controller and the field.

As such, power is amplified, voltages are adjusted or signals are electrically isolated.

The RIF-2 relay modules are particularly suitable for applications in which a high number of contacts is required.

A feedback signal to the controller can be switched parallel to different loads.

Thanks to their high switching power, the RIF-4 relay modules can be used in small power contactor applications. The advantages over contactors are:

• Easy maintenance thanks to plug-in capability
• Operating indicator via status LED
• Inexpensive
• Fast installation thanks to bridgeability and PT connection
