Overview
The Carlo Gavazzi UDM35 universal digital panel meter has been developed to meet the most advanced application requirements. This 3.5-digit modular indicator and controller is designed for current, voltage, temperature, resistance, rate, frequency, speed and period measurements. The UDM35 is a 3.5-digit instrument developed to meet the most advanced application needs. The modular architecture allows engineers to configure only the necessary input and output modules for their specific electrical distribution board or control panel application.
Key Features
- TRMS AC current and voltage measurements with high accuracy and wide dynamic range
- Wide measurement range up to 5A/500V AC/DC, 20kΩ resistance, RTD and thermocouple input with cold junction compensation
- Plug-and-play modules for quick assembly and maintenance
- IP67/NEMA4x front protection degree for harsh industrial environments
- Parameter programming and cloning via optional UDM-Soft software
- Automatic min/max storage in EEPROM with numeric password protection (up to 4 digits, 2 protection levels)
- Four alarm setpoints with fully scalable analog output and RS232/485 serial communication
Technical Specifications
Microprocessor-based 3.5-digit LED display indicator with configurable modules for input/output flexibility. Easy and quick parameter programming and parameter cloning on other UDMs by means of UdmSoft or PC HyperTerminal. Supply rated for 90–260V AC/DC (60V option available). Typical input modules include low-input current (BQ LSX), high-input current (BQ HSX), temperature (BQ TRX), and resistance (BQ TRX). Output options include single analog output (10V, 20mA DC), single relay, dual relay, and dual relay with open-collector modules.
Typical Applications
In automation and process control applications, the digital panel meter visually monitors and controls variables such as temperature, pressure, vibration, and can provide analog and/or serial re-transmission of the measured value for feedback or data-logging purposes. The UDM35 is ideal for:
- Electrical distribution boards and industrial control panels
- Temperature, pressure, and vibration monitoring
- Power quality and energy measurement
- Process automation and feedback control loops
- Field instrumentation in harsh factory environments
