4.2.2 Recommended 24V Power Supply Configuration
This configuration uses a 24V power supply to power the controller board and the 5604 I/O module.
This 24V is used to power the analog circuitry for the analog inputs and output circuits on the 5604
I/O module.
Notes on this configuration:
 The 24V output (VLOOP) can be switched on and off under the control of the application
program to save power to any loads connected to VLOOP.
 It is unnecessary to boost the 24V power in the 5604 I/O Module. The 24V output (VLOOP) on
the 5604 I/O Module can be switched under control of the application program.
 This configuration is recommended when a large amount of current is required at 24V. Refer to
section 10-Specifications and the section outlining sample power calculations in the manual of
your respective controller board to determine the power required from the 24V power supply.
 The Controller Board DC Power terminal must be connected to the same power supply as the
5604 I/O Module DC Power terminals.
