LED lamp provides visual on-off indication of process conditions in safe and hazardous areas, and is suitable for use as part of a panel mounting indicator or illuminated pushbutton assembly.
The P861 LED lamp from RTK Instruments provides visual on-off indication of process conditions in safe and hazardous areas.
It is suitable for use as part of a panel mounting indicator or illuminated pushbutton assembly.
The LED can be supplied separately for use in any suitable standard switch or lamp assembly.
The lamp is current limited to take a maximum of 20mA.
Up to two LED lamps can be driven from a single IIC power source without any effect on the brightness.
The lamps are Atex certified to Ex II 2G EEx ia IIC T4 and are suitable for zones one and two.
The lamps are designed to provide a minimum of 100,000 hours of service life.
They are available in six super-bright colours.
When used in hazardous areas, the LED lamps must be powered through suitable intrinsically safe isolators or barriers.
RTK has a range of suitable interfaces such as the S951 or S967.
The lamps can be supplied as an integral part of the DA170 series of illuminated pushbuttons.
With the lamp's low power consumption, low heat dissipation and long life expectancy, it is suitable for safe and hazardous areas alike.
