Status indicator IS-pB1

LEDpanel-mountintrinsically safe

The IS-pB1 is a compact, panel mount L.E.D. 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. Description 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.
