4.2.3 Recommended Battery Configuration
This configuration uses a 12V battery to power the controller board and the 5604 I/O Module. This
12V 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-boosted output (VLOOP) can be switched on and off under the control of the
application program to save power to any loads connected to VLOOP.
 The DC input (battery voltage) to the 5604 I/O Module can be boosted to 24Vdc on the 5604 I/O
Module under the control of the application program.
 This configuration is recommended when a large amount of current is required at 24V. Refer to
the specifications and the sample calculations to determine the power required from the 12V
battery.
 The 5232 Controller Board DC Power terminal must be connected to the same power supply as
the 5604 I/O Module DC Power terminals.
