The DCP100A or DCP200A pressure modules are designed exclusively for use with the Dwyer® DCT1000 Dust Collector Timer Controller boards for on-demand cleaning requirements. These series of modules are available in 10? w.c. [2.49 kPa] or 20? w.c. [4.98 kPa] ranges, which allow for differential process pressure measurement as indicated on the display of the master controller. An isolated 4-20 mA readout channel is provided for remote pressure display. The 4-20 mA output may be wired either for use with an external power supply and indicator or using the isolated on-board 24 volt power supply to power the loop.
