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.
