RXTUG 21H relay product of ABB company

is a DC/DC converter used to provide auxiliary voltage in industrial systems. This device can convert the input voltage between 110 and 250 V DC to the output voltage of 24 V DC and has binary inputs to enable or disable various functions. Also, this relay has start and trip outputs that automatically reset when the impedance increases. The RXTUG 21H relay is specifically designed to provide auxiliary voltage to protective relays such as the RXZK 21H, and the indicator lights will start flashing when a fault occurs.
