_ 1 Example of an application of the field indicator_ 

The indicator records an analog measuring signal and shows this on the display. The LC display shows the current measured value in digital form and as a bar graph indicating a limit value violation. The indicator is looped into the 4 to 20 mA circuit and gets the required energy from there. 

Measuring system Microcontroller-controlled indicator in single-chamber field housing with illuminated LC display. The measuring range, decimal point and offset of the indicator can be configured comfortably by means of three keys in the device with the housing open or by means of a PC with the FieldCare PC software. 

## Input 

Measured variable Current Measuring range 4 to 20 mA (reverse polarity protection) Input signal • Line voltage drop < 4 V at 3 to 22 mA • Maximum line voltage drop < 6 V at maximum short-circuit current 200 mA 

## Output 

||Output|
|---|---|
|Output signal|Switching output|
||Digital limit switch|
||Passive, open collector:|
||• Imax= 200 mA|
||• Umax= 35 V|
||• Ulow/max≤ 2 V at 200 mA|
||• Maximum reaction time to limit value = 250 ms|
||• Temperature range: –20 to +80 °C (–4 to +176 °F)|
|Signal on alarm|• No measured value visible on the LC display, no background illumination.|
||• Open Collector inactive.|
|Transmission behavior|The indicator allows the HART® transmission protocol to pass unimpeded.|
