The Yokogawa UP750-01 is a highly versatile Programmable Digital Panel Meter (also known as a digital indicator) designed for precise display of a wide range of industrial process signals.<br />
Its core function is to accept an input signal from a sensor or transmitter, perform scaling and linearization if necessary, and present the measured value on a large, easy-to-read display. The "01" in the model number is a key identifier that typically signifies it is a base model with a standard, universal input capability, often pre-configured or most commonly used for basic DC voltage or current signals like 4-20 mA or 1-5V.
Technical Parameters
Category Parameter Specification / Description
Input Signal (Programmable) Types • DC Voltage: 0-5V, 1-5V, 0-10V, ±10V, etc.

Digits 4 or 5 digits (e.g., 9999 or 19999).
Power Supply Standard Options 100-240 VAC, 50/60 Hz or 24 VAC/VDC.
General Performance Accuracy • Voltage/Current: ±0.1% of reading ±1 digit (typical)
• Temperature (T/C/RTD): Varies with sensor type, typically ±0.2% or better.
Sampling Cycle Approximately 0.4 to 0.6 seconds.
Isolation Input is isolated from the power supply.
Communication (Optional) Type Communication options like RS-485 MODBUS may be available as an optional add-on.
Alarm Output (Optional) Type Can be ordered with one or two relay alarm outputs for limit control.
Transmission Output (Optional) Type Can be ordered with an isolated analog retransmission output (e.g., 4-20mA).
Mounting Style Panel-mounted (requires a rectangular cut-out).
Key Applications
The UP750-01 is extremely versatile due to its programmable input. Its most common applications include:
Process Variable Display: Showing values from pressure, level, or flow transmitters that output a 4-20 mA signal.
Temperature Indication: Displaying temperature from RTD or thermocouple sensors.
Signal Monitoring: Monitoring motor loads (with a current transformer interface) or valve positions.
