Dual LED lamp block.

Safe. For every application.

Series 04 Dual LED block (HMI Series) (BR04_KS_01_00473)

As part of Series 04, EAO offers an innovative lamp block. With two LEDs, it facilitates safe and reliable dual illumination.

Typical applications

  • Driver’s cab
  • Operator panels
  • Control cabinets

This illumination accessory is suitable for all illuminable devices in Series 04. The dual lamp block increases operator safety in the driver’s cab or at the operator panel intuitively and with rapid visual recognition. 

The LED lamp block enables visual indication of different statuses in one device. Thanks to the intermittent triggering of both inputs on the dual LED display, the operator can be quickly certain that everything is functioning correctly – or be alerted, as if the input signal fails (0 VDC) the dual LED warning indicator flashes. The intermittent input signals are generated by an external control. The LED technology is durable and offers homogenous, clearly visible illumination, even in strong sunlight and in poor light conditions.

Advantages

  • Allows one device to display different states
  • Dual indication safely signals the failure of one input signal
  • Designed for all illuminated devices of the proven Series 04
  • Reliable LED technology enables long service life
  • Two separate LED's in a single lamp block
