Overview

The Carlo Gavazzi UDM35 (SKU BD35) is a microprocessor-based, 1/8 DIN digital panel meter designed for versatile 1-phase AC/DC and pulse measurements. It features a clear 3.5-digit red LED display and offers True RMS (TRMS) accuracy for precise readings. This modular instrument allows for flexible configuration through plug-in modules, enabling customization of power supply, measuring inputs, serial communications (RS485 or RS232 with MODBUS/JBUS protocol), and digital/analog outputs (optional 20mA/10VDC). The UDM35 supports a wide range of measurements including AC/DC current (200μA to 5A), AC/DC voltage (200mV to 500V), temperature (°C/°F for Pt100, Ni100, TC J-K-S-T-E), resistance (20Ω to 20kΩ), and dual rate, speed, frequency, and period (0.001Hz to 50kHz). It can also accommodate up to 4 independent alarm set-points (optional). The front housing is rated IP67, meeting NEMA12 and NEMA4X standards for protection against dust and water ingress, making it suitable for industrial environments. Measuring ranges and functions are programmable via the keypad or optional UdmSoft software. The UDM35 includes min-max storage functions and double-level password protection. Applications include process industries, agriculture, plastics, food & beverage, and packaging.
