• DC Current: 4-20 mA, 0-20 mA (with external shunt resistor).
• DC Voltage: 1-5V, 0-5V, etc.
Display Type Single-character, high-brightness LED display.
Displayable Characters Limited set: Numbers -1, 0, 1, 2; Letters such as H, L, P, F, U, O, etc.
Power Supply Standard Voltage 24 VAC/VDC (or other ranges like 100-240 VAC, depending on the order code).
General Performance Setting Method Configured via internal DIP switches and a simple calibration potentiometer to define the input signal range and the display character trigger points.

Key Applications
The UP550-00 is used in applications where space is limited and clear status is critical:

Alarm Acknowledgment Indicators: Displaying "H" to show a high alarm has occurred and may require acknowledgment.

Machine State Indicators: Showing "1" for RUN and "0" for STOP based on a contactor auxiliary signal (converted to a voltage).

Limit Monitoring: Displaying "L" when a measured value (like level or pressure) is below a minimum threshold.

Fault Indication: Displaying "F" upon receiving a fault signal from a device.
