Reliable, high-brightness visual indication of process conditions for safe and hazardous areas from RTK Instruments Ltd
The DA180 range of Giant LED Clusters, having a 66mm diameter lens, not only provides clear indication from a distance but is also visible from the side. Lenses are available in six super-bright colours and feature an integral current regulator to limit the current to 20mA. This ensures that all colours are matched to obtain consistent brightness across the range including white and blue. Up to two LED Clusters can be driven from a single IIC power source. The lamps are designed to provide a minimum of 100,000 hours of service life.
The DA180 Giant LED Clusters are ATEX Certified to Ex II 2G, EEx ia IIC T4 and are suitable for zones 1 and 2.
The LED Clusters can be supplied as loose parts or pre-mounted in a stainless steel or polycarbonate IP65 box ready for immediate installation on site.
The DA180 range of Giant LED Clusters can be linked into either the LN1000 Intrinsically Safe Alarm Annunciator or one of a number of safe area annunciators.
With the LED’s lower power consumption, low heat dissipation and long life expectancy, the DA180 is an ideal indicator for safe and hazardous areas alike.
The DA170 range of LED Clusters provides visual on/off indication of process conditions in safe and hazardous areas. Available in six super-bright colours - red, green, yellow, orange, blue and white - they are standard 22.5mm diameter and seal to IP65 to the panel door.
All six colours are fully current limited and take only 20mA. All are matched for equal brightness including the white and blue versions.
In hazardous areas it is possible to combine LEDs from a single Intrinsically Safe interface, two for IIC interfaces and four with a IIB interface.
The standard LED Cluster can also be supplied fully mounted in stainless steel boxes ready for immediate mounting on-side.
With the LEDs lower power consumption, lower heat dissipation and far greater life expectancy the DA170 is an ideal standard indicator for safe and hazardous areas alike.
