Schneider Electric XVBC2B8 Harmony XVB Yellow 70 mm Indicator

XVBC2B8 yellow 70 mm steady indicator bank unit

The XVBC2B8 is a Schneider Electric product listed in the datasheet as: Indicator bank, Harmony XVB, illuminated unit, plastic, yellow, 70mm, steady, integral LED, 24V AC/DC. The XVBC2B8 is a yellow Harmony XVB illuminated unit of 70 mm with steady light and an integral LED. Yellow typically warns of attention or abnormal conditions. Seven Star LLC supplies the XVBC2B8 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: B marks the LED variant and 8 the yellow colour. The datasheet shows it as discontinued.

Technical specifications of the XVBC2B8

Warning-light data of the XVBC2B8

Supply voltage: 24 V AC/DC.

The datasheet gives supply and consumption.

Using the XVBC2B8 in a tower

Yellow is placed between green and red. The green sibling XVBC2B3 shares the same base.

The datasheet downloaded for this page carries lifecycle notices: Discontinued on: Dec 31, 2025; End-of-service on: Jul 1, 2026. For a plant that already runs this reference that makes the XVBC2B8 a spare-and-replacement item, and it is worth fixing the stock level and the long-term successor plan at the same time. We can discuss compatible alternatives once we know the installation.

Typical applications of the XVBC2B8 in Oman and the GCC

In Oman and the GCC it flags warnings on equipment.

Dimensions, environment and approvals of the XVBC2B8

The XVBC2B8 weighs 0.15 kg. Mounting, derating and enclosure choices follow the environmental data below, which should be compared with the actual panel temperature and the dust and humidity of the site in Oman and the GCC.

Ambient temperature limits in the datasheet: -40 to 70 °C. Ingress protection: IP65 on fixing base XVBZ0. IEC 60529; IP66 on base unit IEC 60529. Standards listed: IEC 60947-5-1. Certifications listed for this reference: CCC; EAC; CSA C22-2 No 14; UL 508.

A yellow unit like the XVBC2B8 is the attention colour in a signal tower, and its meaning should be defined in the plant standard: many sites use yellow for a warning that needs action but not an immediate stop, such as a low level, a filter blocked or a maintenance request. Wire it to a controller output through a relay or direct, as its LED consumption is low; check the datasheet for the current. The 70 mm yellow lens can look similar to an orange or amber lens in strong light, so avoid using both in one tower. The unit is part of a family with other colours such as the green XVBC2B3, and the units can be exchanged on the base to build a custom stack. As the datasheet lists the unit as discontinued, record the base type and tube length with the spare so a replacement can be selected quickly. Clean the lens regularly, since dust reduces visibility. When a tower has been in service for several years, plan a periodic lamp test: operators should see every colour light at least once a shift or after each start, so that a dead yellow unit is found early. Keep a simple one-page legend near the machine that states what steady yellow means and who should be called. If the plant also uses flashing yellow for a different meaning, document the difference clearly. Replace units in complete sets when the lenses on the same tower have started to yellow with age, so the colours stay matched.

Site conditions in Oman for the XVBC2B8

Safety and analytical equipment in Gulf plants has to perform reliably in heat, dust and humidity. Before installing the XVBC2B8, check the operating temperature range, ingress protection and hazardous-area approvals against the actual location, and consider shading or weather protection for units exposed to direct sun. Sensor positioning should follow the gas properties and the site fire and gas philosophy, with access kept clear for testing.

Plan the test and calibration routine from the start. Record the configuration and alarm settings of each XVBC2B8, keep the required calibration gas or test equipment available, and agree a replacement interval for consumable parts so that the system stays compliant with the inspection regime at sites across Oman.
