The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Schneider Electric - Model: ZBV-BG4 - Condition: Used and in Excellent Condition - Price: $25.00 USD - Availability: In stock, 1 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 0.5 lb, estimated - Shipping dimensions: 8X8X3 in, estimated ## Categories - Industrial Systems Equipment > Safety and Security (primary) ## Overview Illuminated light block component designed for use in modular signaling systems, compatible with Harmony XB4/XB5 control and signaling products, supports 24V AC/DC operation. It interfaces with pushbuttons and selector switches, using a snap-in mounting for secure attachment. The device features LED technology for energy-efficient illumination and long operational life. The module includes quick-connect spring terminals for ease of wiring. Commonly applied in industrial control panels and machine interface systems for enhanced visibility of control status or fault conditions. ## Function Provides red visual signaling via an integral LED light block designed for 22 mm Harmony XB4 and XB5 illuminated push-button or selector switch heads; operates on 24 to 120V AC/DC supply; connects via vibration-resistant screw-clamp terminals for secure mounting; enables fast replacement and configuration of control panel indicators; plastic body with IP20 protection prevents accidental contact with live parts; suitable for industrial control and signaling applications under a wide temperature range (-40°C to 70°C). ## Platform Suitable for control panels, industrial machinery, and automation systems; designed for compatibility with Harmony XB4/XB5 series operators; integrates into 22mm diameter panel cutouts; utilizes screw clamp terminals for secure connections; operating temperature range -25°C to +70°C. ## Application Light blocking, used for safety in industrial settings to prevent light-based hazards. Designed for use in industrial control systems, and often found in proximity to automated machinery. Interfaces with other equipment via hardwired connections, possibly using a programmable logic controller (PLC) or safety relay. ## Accessories Green LED light module for XB4 and XB5 series push buttons and pilot lights. Requires BA9s base lamp holder. Compatible with 22mm mounting holes. Spring-clip mounting to operator body. Accepts 24V AC/DC power through screw terminal connections on lamp holder base. IP65 rated when properly assembled with compatible bezels and operators. Integral current limiting resistor included. Quick-connect terminals allow daisy-chaining multiple light blocks. Compatible with ZBV-B or ZBV-M series lamp holders and standard or heavy-duty operator heads. ## Interface Integral red LED light block with 22 mm diameter for panel mounting; operates at 24 to 120 VAC/VDC; screw-clamp terminals for electrical connection; designed for clip-on installation to Harmony XB4 and XB5 illuminated push-button or selector switch units; protection rating IP20; compatible with 50/60 Hz supply frequency; screw terminals accept standard cross-head (Phillips #1, Pozidrive #1) and slotted screwdrivers (4 mm and 5.5 mm diameters) for torque tightening (0.8 to 1.2 N·m); plastic housing; vibration-resistant terminal design. ## Images - - - -
