Connecting dual channel inclinometer to SIRIUSiwe

HI,


Are you able to assist with connecting a SIRIUSiwe-6xSTGM-2xSTGM+ to a dual channel inclinometer, powering the inclinometer from the Sirius? Inclinometer is a DAS-30A (Input supply 7-30V 20mA)


As the sensor is dual output, we will be connecting to 2 Sirius channels, I have come up with the below 2 wiring diagrams (matching the OEM wiring colours, with the exception of White being shown as grey).


I'm unsure if one method is preferred (or if neither are suitable). The 2 options being:

  1. Provide power to the sensor between the Exc+ and Gnd with the excitation voltage set to 15, providing the sensor nominally 7.5V (approx. 20mA required by the sensor)
  2. This seems to be a more simple option, however Im unsure if this will be getting close to the channel excitation current limit given it would only be using one half of the supply.
  3. Power the sensor between the Exc+ and Exc- (Excitation voltage 10-15V) and calibrate out the scaling offset from not referencing Gnd.
  4. I'm unsure of the correct method to connect the second axis WRT connecting EXC+ and SNS+ and GND to IN-.

Option 1

Can you please confirm the below wiring diagram is correct?



Option 2

Can you please confirm the below wiring diagram is correct?

For the X-Axis (I believe the X- Axis is correct)

  1. Power being provided from the X-Axis between Exc+ and Exc-.
  2. Scaling of the sensor will need to be corrected since the reference will not be GND but EXC-.
  3. A short circuit between pin7 & pin4 will be needed, this manually connect the input as a 3-wire single ended mode with the power sensor.


For the Y Axis I'm uncertain if the diagram below is correct

  1. Do I need to connect Exc+ to Sns+?
  2. Does GND and IN- need to be connected in this case?
  3. Is connecting a common sensor ground from the X-Axis and into the Sns- and Exc- the correct method?



Thanks
