DM4500U Panel Meter

Brand: Status Instruments

The DM4500U accepts various types of sensors including Load Cell, Pt100, thermocouple, potentiometer and process current or voltage enabling the DM4500U to be used in a wide variety of applications.

Output options are provided that include NPN / PNP, 2 or 4 relays, current / voltage and RS485 comms. The unit can be fully programmed from the front panel buttons or via the RS485 comms option.

All parameters can be entered by pressing combinations of the three sealed front panel keys through a series of menus in helpful mnemonics or via the optional communications port.

The display can be programmed to read in three different colours and two levels of brightness. Red, Green and Orange. Colours can be programmed in a variety of different ways. For example alarm, normal running or high scale can be displayed in different colours.
