ABB AF-RA4 Interface Relay: Efficient 24 V DC Signal Conversion with Built-in Surge Protection and Easy Installation
ABB
$143.78
The ABB AF-RA4 interface relay is an essential component for systems requiring the conversion of low-power 24 V DC signals from PLCs or other sources into sufficient power to operate AF09 ... AF96 contactors or NF contactor relays. This compact electromechanical relay features a normally open (N.O.) contact and a low-consumption 24 V DC coil, ensuring efficient signal transmission and power switching. The RA4 is equipped with built-in surge protection to safeguard against overvoltages, enhancing the longevity of electronic devices and components. Additionally, a diode between the E1 and E2 input terminals prevents relay pole reversal, ensuring reliable operation. For easy installation, the RA4 connects to the PLC-output via the "E1+" and "E2-" terminals and interfaces with the contactor coil through the A1 and A2 terminals. The RA4's design allows for quick mounting by clipping it onto the contactor without the need for screws, streamlining the setup process.
