GE RR7 - 20A SPST Low Voltage Relay Total Lighting Control

GE Model RR-7 isa mechanical latching-type unit requiring only momentary 24 VAC switch circuit pulses to open or close line voltage circuits.

All GE low voltage relays may be used to full-rated capacity for tungsten filament, ballast, or resistive loads.

Positive action

The relay always goes to the state commanded. For example, multiple off commands will simply keep the contacts in the off position.

Stable operation

Since the relay latches in the on or off position, power outages do not result in a change of state.

Minimal power consumption

Control power is only required when the relay changes state.

Additive control functions

Pulse control signals coupled with latching allow any number of switches or electronic control devices to operate the same relay. The relay position is always dictated by the last signal.
