6.7 ANALOG INPUTS FOR 3
RD
PARTY TORQUE METER
It is possible to connect a 3
rd
party Torque meter (torque-, speed- and power) to the SDB-3. This 3
rd
party
torque meter needs to be equipped with analogue 4–20mA outputs.
The analogue 4–20mA signals can be connected to the SDB-3 representing the torque-, speed- and
power-signal.
Analog input:
Signal
Type of input signal
Terminal number on SDB-3
Shaft torque signal
4–20mA - active
Terminal nr. X1 and X2
Shaft speed signal
4–20mA - active
Terminal nr. X3 and X4
Shaft power signal
4–20mA - active
Terminal nr. X5 and X6
When passive analogue outputs must be connected to the SDB-3 please contact VAF Instruments.
NOTE:
Do not connect the signal ground to the ship hull.
NOTE:
The maximum number of analog inputs is 6 inputs, divided across two IO-modules.
