Ex-box LED: Same as the ex-box DIS with ex-control except for the following: no personal computer bus-card, but interface and supply (8.2 V 100mA).
The Ex-Box LED is a temperature controller developed by eltherm for use in hazardous areas, with similar features to the Ex-Box DIS, but with a simpler interface. Essentially, it is a version of the Ex-Box DIS without a personal computer bus card and providing status information via LED indicators.
