PD900 Consolidator Multi-Channel Controller

USA Toll Free: 1-800-730-0302 Tel: 416-240-1920 -

The ConsoliDator® PD900 is an easy-to-use, multi-channel controller that accepts up to eight (8) 4-20 mA inputs, four (4) flowmeter pulse inputs, and up to eight (8) digital inputs, then displays them on a large, backlit, graphical LCD screen. It is available in four models: the PD940 (4 input, wall mount), the PD941 (4 input, panel mount), PD980 (8 input, wall mount), and the PD981 (8 input, panel mount). While programming the meter, onscreen soft keys appropriately and clearly relabel the action of the front panel buttons making menu navigation quick and simple. In operating mode, the ConsoliDator’s main screen displays all the inputs in both numeric and bar graph format and its individual screens display detailed information about each. The ConsoliDator is suitable for all safe area monitoring and controlling applications such as flow, level, pressure, temperature, and vibration. The availability of Modbus® RTU serial communications makes it ideal for SCADA applications.
