Carlo Gavazzi offers a comprehensive range of digital panel meters and digital displays (current meters, ammeters, voltmeters, frequency meters, temperature meters and temperature controllers, tachometers, and rate meters) for the OEM, Panel Builder, Instrumentation, and MRO customer.

Covering most input types (current/voltage/temperature/resistance/RPM), Gavazzi digital panel meters are well suited for your display requirements.

The UDM series is a hi-tech modular panel meter family developed to meet your most advanced application needs. The series is available with either a 3 1/2 digit (UDM35) or 4 digit (UDM40) display. It can also be ordered without a display and be used as transducer or signal conditioner (USC).

The UDM series accepts most signal inputs (current, voltage, temperature) and offers an analog output as well as up to 4 digital outputs (relay). Since these are modular meters, outputs can be added at any time in the field. Remote monitoring via a PLC or PC is possible by inserting an RS485 communication module into the meter. In this way many meters can be monitored without adding a lot of expensive Analog cards to your PLC.

The UDM40 meter also features a 3-colour display allowing at a glance indication of relative operating condition (OK - Green, Caution - Yellow, or Alarm - Red). Furthermore, the UDM40 is also able to handle and correctly display non-linear signals.
