Colored LED DA170

squareclusterintrinsically safe

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, amber, orange, blue and white - they are standard 22.5mm diameter and seal to IP65 to the panel door. The DA170 Intrinsically Safe LED Clusters are ATEX Certified to Ex II 1G, EEx ia IIC T4 and are suitable for zones 0, 1 and 2 and for all gas groups. 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-site. With the LED’s lower power consumption, lower heat dissipation and long life expectancy the DA170 is an ideal standard indicator for safe and hazardous areas alike. In addition to the standard LED Clusters, RTK can provide a complete matching range of pushbuttons, selector switches and emergency-stop buttons. Most of the pushbuttons and selector switches can be supplied in either illuminated or non-illuminated versions, thus giving your intrinsically safe control panel a consistent appearance.
