Intrinsically Safe Display Units

Intrinsically safe LCD and LED displays are designed to display the current measured value in potentially hazardous area. Variability of the device allows the measurement and processing of any input range in any dependence on the input variable. LCD and LED displays can be made in panel or outdoor variant. LCD display units are powered directly by current loop 4-20mA of intrinsically safe circuit and require no additional power supply. It is a device without an additional energy source with zero internal inductance and minimal capacity. Devices may be connected into the intrinsically safe loop circuit without requiring any additional certification. LED display units are powered from intrinsically safe source and are designed as an pass-through device for intrinsically safe current loop. This is not a passive device and requires certification for use in potentially hazardous areas.
