The RR9PBP is a mechanical, latching-type relay designed for direct plug-in installation within a GE Lighting Automation Panel. It is part of the GE low-voltage relay family used in relay-based lighting control systems and is intended to operate as a field-replaceable switching component.
This page provides structured technical context for the RR9PBP relay with emphasis on its use in current GE LightSweep systems, while also addressing legacy installations encountered during modernization and upgrade projects.
Relay Description and Operating Principle
The RR9PBP is a mechanical latching relay used to switch line-voltage circuits while being controlled by a low-voltage signal. As a latching device, it maintains its last commanded state without requiring continuous coil power, remaining either open or closed until a new control pulse is applied.
The relay is actuated using momentary 24-volt rectified AC switch circuit pulses. These pulses command the relay to change state, minimizing control power requirements during normal operation.
The coil design resists burnout that could occur if control equipment or operational failures caused extended energization, supporting long-term reliability in lighting automation panels.
Integration with GE Lighting Automation Panels
The RR9PBP relay is designed for direct plug-in installation using a 5-pin connector. This allows the relay to be installed or replaced without additional wiring, simplifying service and maintenance activities.
Once installed, the relay operates as part of the panel’s relay switching subsystem, receiving control pulses from panel electronics and switching connected lighting loads accordingly.
Because the relay is mechanically latching, its state is preserved during power interruptions without continuous coil energization.
LightSweep Focus and Legacy Context
The RR9PBP relay is used in both modern GE LightSweep systems and older GE relay-based lighting control panels. From a lifecycle perspective, Chipkin’s recommended direction for most sites is to plan upgrades toward LightSweep rather than extend the lifecycle of legacy TLC infrastructure.
In practice, the RR9PBP is commonly encountered when maintaining existing panels or during phased retrofit projects where relay hardware remains in place while control platforms are modernized.
Status Feedback and Load Types
The RR9PBP includes a pilot contact that provides relay status feedback. This status is displayed through LED indicators mounted on RINTERxxyy interface modules, allowing visual confirmation of relay operation.
GE low-voltage relays, including the RR9PBP, may be used to full rated capacity for switching tungsten filament, ballast, or resistive loads when installed within supported lighting automation panels.
