POWER MONITORING CURRENT SWITCH AND RELAY RIBX SERIES
DESCRIPTION The Relay in a Box RIBX Series provides a unique and cost-effective solution to on/off motor control and current sensing status indication. Combined in a single, convenient junction box with high and low voltage separation are a control relay and a current sensing status switch. A three-position closed/open/auto switch is available to override the output of the relay. This versatile product allows both control and status sensing of electrical loads by a BAS, all in a self-contained, easyto-install housing.
RIBX - Ring Remote Current Sensing
RIBX - Internal Current Sensing
FEATURES • Cost-effective current sensing with a control relay • Self-contained housing with high and low voltage isolation • LED indication of relay and sensor trip • Optional relay contact override switch • Plenum rated housing • UL listed for UL 916 Energy Management and UL 864 Fire
RIBX - Split Ring Remote Current Sensing
APPLICATION Internal Current Sensing (for single-phase loads) Models with internal current sensing are great for direct control and current sensing of exhaust fans, pumps, and other single phase electrical loads up to 20A. The control relay contacts of these models wire directly in series with single-phase motors using the wires that exit the housing through the 1/2" conduit hub. The current of the load is sensed within the housing. Low voltage wiring from the controller for the control relay coil and status switch enter the separate Class 2 wiring compartment in the housing through star bushings or conduit and are connected to screw terminals. Remote Current Sensing (for loads with motor starters) Models with remote current sensing are great for control and status sensing of electrical loads that require a motor starter. The control relay contacts of these models are wired in series with the motor starter coil using the two wires that exit the housing through the 1/2'' conduit hub. Currents up to 150A are sensed externally with a current sensing ring connected to the two gray wires that also exit through the 1/2'' conduit hub. Low voltage wiring from the controller for the control relay coil and status switch enter the separate Class 2 wiring compartment in the housing through star bushings or conduit and are connected to screw terminals.
