DM3600 Intelligent Panel Meter

Brand: Status Instruments

The DM3600 is an intelligent digital panel meter that can accept inputs from a wide variety of sensors and display the signal digitally.

In addition, it has the facility to accept up to two option ‘Pods’ which can be either isolated (4 to 20) mA re-transmission or two alarm relays. The DM3600 is available in two models. The DM3600U which is a universal input panel indicator and the DM3600A, a universal panel indicator with totaliser functions.

All functions are programmable via the integral front panel keys or via the optional RS-485 serial communications port using the Modbus protocol.

The DM3600 supports TFML (Transfer Function Module Library) i.e the ability to download custom functionality by means of standard modules available from the web site. This allows pre-written or custom control functions to be quickly and easily incorporated.

The DM3600A totaliser function enables non-volatile storage of the integrated total to be maintained within the unit, even after loss of power. Output options can be selected to operate on Process Variable (PV) or Total.
