Wiring requirements for all pressure sensors are given in the table below.
Sensor and energisation options
9 way D connector wiring details
Absolute Current Output
(2 wire) sensors
using 15V excitation from the pressure board
to energise the sensor.
Pins (1,3) and (2,5) are linked inside the
connector shell.
Pins 2 and 3 are not interchangeable.
Absolute Current Output
(2 wire) sensors
using external excitation to energise the
sensor.
Pins (1,3) and (2,5) are linked inside the
connector shell.
Pins 2 and 3 are not interchangeable.
Absolute Voltage Output
(3 wire) sensors
using 10V or 15V excitation from the pressure
board to energise the sensor.
Pins (2,5) are linked inside the connector shell.
Pins 2 and 3 are interchangeable but the
wiring shown is recommended
Absolute Voltage Output
(3 wire) sensors
using external excitation to energise the
sensor.
Pins (2,5) are linked inside the connector shell.
Note: If the sensor output can exceed 5V then
configure the board to give additional
excitation to bias the sensor output between
+5V and -5V.
Pins 2 and 3 are interchangeable but the
wiring shown is recommended
