The SG auxiliary relays are for use in miscellaneous automatic and remote control switching. It is suitable for many industrial applications. SG relays are supplied for use on the following voltages without an external resistor by use of suitable coils. The standard coils are 6,12,24,48,125 and 250 volts DC. 115 and 230 volts at 25Hz and 115,230,440 and 575 volts at 50/60 Hz.
External series resistors are used with the voltage rated dc relays, for higher control circuit voltages upto 600 volts dc. Relays having limited time-delay in operation are also available.
