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