  • 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

The lamp block allows one device to display different states in a unique way. Thanks to the pulsed control of the two inputs for the dual LED display, the user gets quick, positive feedback of proper operation.  Or, if one input signal fails (0 VDC), the LED display flashes a warning. The pulsed inputs need to be generated by a upstream, external control.
