The PD865 Snooper is a digital panel meter that can be
programmed as a Modbus RTU Master, Slave or Snooper.
What Makes Snooper Mode Special?
In Snooper mode, the Snooper can sit anywhere on the Modbus
network and display any process variable on the bus. The special
thing about Snooper mode is you don’t have to change the
programming of the other devices on the network. You just program
the Snooper to listen for a specific address and register on the bus
and it constantly monitors that location and displays the PV on the
digital readout.

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 RS485 serial communications port using the Modbus protocol. To facilitate integration into a Scada system, an OPC server is available which also interfaces to the MEDACS, smart DIN rail Signal Conditioner product range, seamlessly integrating front and back of panel instruments.

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.

The unit is microprocessor based and set up is achieved by means of three push button switches located on the underside of the module following a simple menu structure. The (4 to 20) mA loop powered indicator can have a number of standard linearisations applied, such as square root, or a custom characteristic can be entered. Rtd and Thermocouple versions can be combined with a (4 to 20) mA transmitter (two wire current sink) with the transmission range set from the push buttons.

The DM700 series can be fitted in a selection of enclosures to achieve IP67 sealing.

A unique feature of the RTD input is the ability to enter sensor calibration data to achieve an exact match for greatest accuracy.
