Precision Digital PD900 Consolidator Multi-Channel ControllerLast Updated: 31/01/2019
RM6,140 – RM7,453
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.

Free PC based software is included with every ConsoliDator. With this software the user can monitor process variables, relay states, alarm states, and switch input states. The software can be used as a data logger, or to configure the ConsoliDator.
Click here to download Consolidator software.
On the main display screen of the software, the bargraph display not only shows the current PV value, it also shows any set and reset alarm points (gray lines on bargraph). On this screen you can also monitor relay and switch input states.
Recent History Viewer
When an input channel is selected on the main display screen, a graph of recent history (last 5-10 minutes) can be viewed. A bargraph of its current value is also present.
The data logger allows you to log the PVs over time. A CSV file is created so that the data can be used by a spreadsheet program. Log rate intervals can be set from 1 second to 10 minutes.
The ConsoliDator can be remotely configured with this software by inputting the configuration data directly, or by copying a configuration from another ConsoliDator. Configurations can also be saved to your computer for future use.
The connectors diagram is silk-screened on the back of all panel mount ConsoliDators (PD941 shown here).
