Model 5900 D/P Module EX-1710-1 Application The D/P Module is a pneumatic-to-current, differential pressure transmitter. It provides a two-wire 4-20 mA output signal suitable for process control or tank level gauging. Model 5900 D/P Module This surface mount transmitter is intended for control room or other protected locations. -
Page 5: Pressure Connections
Model 5900 D/P Module EX-1710-1 Pressure Connections Power Requirement D/P Module Transmitter incorporates two (2) 1/8" NPT The D/P transmitter requires a source of DC power (14– 40 ports for HIGH and LOW differential pressure inputs. Vdc) for operation. Minimum excitation voltage must be no less than 14 Vdc Any receiver installed on the signal vent plug for atmospheric reference (or low pressure loop (meters, data loggers, controllers, etc.) must be taken... -

Model 5900 D/P Module EX-1710-1 Test Point Terminals (TP1, TP2)—Test meter terminals In-Process Zero/Span Adjustment are provided (see diagram) for measuring the output signal It is possible to make adjustments to the zero setting while without disturbing the signal loop. Do not connect any the D/P transmitter is installed at the tank. - Page 7 Model 5900 D/P Module EX-1710-1 D/P Range Adjustment DIP Switch Settings DIP Switch The D/P transmitter span can be adjusted from 70% Maximum mA to 140% of the nominal range indicated by the model Output number. (Refer to Model No. Designation on page 3.) This 1 2 3 4 is how the transmitter’s pressure range can be changed for a specific application.

Model 5900 D/P Module EX-1710-1 Low Pressure Input Coarse Range Setting—Alternate Version Previous versions of the D/P transmitter employ similar DIP switches, but only offer 5 increments of coarse adjustment. Internal Tank Pressure or Vacuum With these versions, the span potentiometer offers greater In a closed, pressurized or evacuated tank, it is necessary to range of adjustment. -
Page 9: Calibration Test Setup (Typical)
Model 5900 D/P Module EX-1710-1 Calibration Test Setup (Typical) This D/P transmitter has a specified accuracy of ± 0.15%. To ensure your calibration maintains this degree of accuracy, 20.00 the equipment used to check zero and span settings must conform to the recommendation listed below. Use of equipment with less than specified accuracy figures will not VOLTS AC provide acceptable results. -
