IS-pB1 Panel Mount Indicator  
  
 The IS-pB1 is a compact, panel mount LED indicator providing reliable cost-effective visual status indication in all hazardous areas. Each IS-pB1 contains a group of high efficiency light emitting diodes mounted behind a coloured diffuser to produce a bright, uniform output with a typical life greater than ten years.
  
 All models contain a 20mA current regulator which maintains constant brilliance and provides protection against excess voltages.
   
  
 Features  
  
 • Two lamps may be powered from a single IIC  
   intrinsically safe Zener barrier or galvanic isolator and up to four lamps from a IIB device.
 • Red, amber, green, blue and white comply with the
   indicator light colour requirements specified in IEC204-1, allowing all plant conditions to be annunciated.
 • Mounting is via a single industry standard 22.5mm  
  diameter hole.
