Product Description:

The 4E0031.01-090 is a front-panel indicator module supplied by B&R Automation within the 4E0 PanelWare Accessories series. Intended for embedded use in control desks, switchgear doors, or operator panels, the device consolidates multiple status lamps into a single compact carrier. It provides a straightforward way to route discrete outputs from PLCs, alarm contacts, or sensor clusters to a visible light strip, allowing operators to verify machine states without opening the enclosure or using diagnostic software.

Its internal logic draws a base current of 1.5 mA at 24 VDC, while each indicator consumes 3 mA, allowing efficient loading of I/O drivers. A bank of 8 yellow LEDs provides individual channel displays, and a single label field allows the group to be identified clearly. The module operates from 0 °C to 50 °C and tolerates relative humidity between 5% and 95% throughout that temperature range. Its low current requirements minimize heat generation and permit direct connection to compatible sourcing or sinking transistor outputs without additional relays. Descriptors such as “Axis Ready” or “Safety Chain” can be placed in the label field so the purpose of the indicator row is easy to understand.

During storage and transportation, the assembly withstands temperatures as low as -20 °C and as high as 60 °C. It withstands shocks of up to 15 g for 11 ms, helping protect the solder joints and LED lenses from damage caused by sudden impacts. The module also tolerates continuous vibration of 9.8 m/s², applied for 20 cycles on each axis with a peak displacement of 0.075 mm. This vibration tolerance supports installation near machinery that produces persistent low-level movement during normal operation. The module can be secured to standard panel hardware without separate vibration dampers when the mounting surface and fasteners meet the installation requirements.
