5.7 DX1 digital extension module
The digital extension module has two galvanic separated digital inputs and two general-purpose relay outputs.
The digital inputs are primarily intended for use as direct RPM pickup input(s), but may be configured differently.
5.7.1 DX1 input circuit - principle diagram
The two digital inputs are identical, and the principle diagram below illustrates the main function.
The input circuit is protected for over- and reverse-voltage.
The threshold (or trigger) level is set up in the relevant setup profile (it cannot be changed from menu).
The setup will be one of 4 fixed levels, intended for input signals of respectively 5 V, 12 V, 24 V or 30 V.
The input voltage level must not exceed +/-32 V DC.
Please see the XDi data sheet for specific technical data.
