Chapter 2 Installing the XM Dynamic Measurement Module
Connecting the Power Supply
The power supply to the module is nominally 24V DC. The Class 2 power
supply connection provides power to the device and other XM modules
located on the DIN rail.
When wiring the DC input power supply to the terminal base unit, connection
may be made as shown in Figure 2.6. Also refer to Figure 2.1 on
page 19 .
Tachometer
34 Tach/Signal In (+) Tachometer transducer/signal input, positive side

36 Functional Earth Shield return for Tach/Signal cable
Connection to DIN rail ground spring or panel mounting hole
37 Tachometer 24V (-) Tachometer power supply output, negative side
-24V relative to Signal Common (terminal 41)
38 Tachometer 24V (+) Tachometer power supply output, positive side
39 TACH Buffer Isolated from terminal 34 by a resistor
40 Tach/Signal (-) Return for terminal 39 or connect to terminal 41 for powered Tach
transducer when TACH Buffer is not used
41 Signal Common
