Description
The SX-20NE-RT shall be housed in a magnetic shielding NEMA steel enclosure. It shall operate from 120 volts AC and have a barrier strip accessible through knock-outs in the enclosure for hardwiring power input and output connections. Overall dimensions shall be 12.0″ H x 12.0″ W x 4.0″ D. Weight shall be 12 pounds. The unit shall have remote turn-on capabilities enabled by a hardwired connection to a separate terminal block within the enclosure. Remote turn-on and turn-off shall be activated by either a contact closure or applied DC voltage. There shall be an output voltage source for connection to a remote LED status indicator and a relay output for control and cascading. The SX-20NE-RTshall have a load rating of 20 amps at 120 volts, a self-test circuit with visual indicator and provide EMI/RFI filtering. It shall withstand at least 1000 occurrences of surge pulse voltages up to 6000 volts.
