Description
RA4 is an interface relay designed to receive 24 V DC signals delivered by PLC’s or other sources with a low output power and to restore them with sufficient power to operate the coils of the relevant AF09 … AF96 contactors or the NF contactor relays. RA4 interface relay is made up of a miniature electromechanical relay equipped with a N.O. contact and with a low consumption 24 V DC coil. The interface relay coil is controlled by the PLC while the N.O. contact ensures switching of the power contactor.
• Easy to install: less compact than other market solutions, RA4 is simply clipped on the top of the contactor
• Optimum interface: it accept all 24 VDC low outpout power signals down to 20 mA 24 V DC
• Optimize your logistics and cost, thanks to 1 single RA4 interface relay for AF09…AF96 / NF monitoring control voltages up to 250V AC, without any additional accessory or wiring for assembling.
