Kirjeldus
RA5-1 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 contactors.
RA5-1 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.
Coil switching gives rise to overvoltages which have adverse effects on the electronic devices, insulators and, more generally, on component lifetime. The RA5-1 is equipped with surge suppressors:
• on the 24 V DC relay coil via a diode,
• on the power contactor coil via a varistor.
Furthermore, the RA5-1 is protected against relay pole reversal by a diode inserted between the E1 and E2 input terminals.
