Why Choose the ABB RA4 Interface Relay?
The ABB 1SBN060100R1000, type RA4, is a compact interface relay designed to allow low-power PLC outputs and control signals to operate ABB AF contactors and NF contactor relays. It provides electrical isolation and signal amplification between automation controllers and contactor coils, making it ideal for modern industrial control systems.
The RA4 interface relay accepts 24 V DC control signals from PLCs or other low-output-power devices and uses an internal electromechanical relay with a normally open contact to switch the associated contactor coil. This allows reliable integration of automation systems with ABB contactor ranges from AF09 to AF96 and NF contactor relays.
With its compact clip-on mounting design, the RA4 can be installed directly onto compatible ABB contactors without additional mounting hardware. Its low power consumption and built-in protection features make it a practical solution for industrial automation panels and motor control applications.
