DM4500F Panel Meter

Brand: Status Instruments

The DM4500F accepts various types of pulse and frequency inputs to display Rate, Totalise, Flow, RPM and Pulse Count enabling the DM4500F to be used in a 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. When used as a frequency meter and pulse counter, 5 digit resolution is provided.

The totalizer function has an 8 digit resolution displayed in 2 parts. 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.
