Figure 2: 5232 Controller Module
3.2 Power
Supply
The SCADAPack 32P controller is primarily a DC input powered device but can be powered with
16Vac under some conditions. The power supply requirements for the 5232 Controller board are
each explained in the following sections.
NOTE:
Voltages referred to as Vrms (or Vac) indicate AC power. Voltages referred to as V (or
Vdc) indicate DC power.
3.2.1
Controller Board Power Supply
The 5232 Controller board can be powered from a 12Vdc to 24Vdc power source applied to the DC
PWR input or a 16Vac power source applied to the AC PWR IN input. With input power applied the
5232 Controller board power supply provides an internal 5V output to power 5000 Series modules
through the inter module cable (IMC).
The 5V supply has a 1.3A output capacity of which 500mA is required by the 5232 Controller board.
The remaining capacity, 800mA, is used to power 5000 Series modules connected through the IMC
cable.
When the 5232 Controller board is powered with 16Vac power applied to the AC PWR IN input a
limited amount of 24Vdc power is provided on the DC PWR terminals. The amount of 24Vdc power
available is dependent on the amount of 5V output power used in the system. With a 5Vdc output
power of 500mA there is 300mA is available and this value is derated linearly to 100mA with a
5Vdc output power of 1.3A.
3.2.2
Power Supply Input Connections
Input power is connected to the SCADAPack 32P controller in one of the following ways:
•
A 16Vac source connects to the AC PWR IN terminals on the 5232 Controller board. See section
Recommended AC Power Supply Configuration
for an example of using a 16Vac
transformer to power the SCADAPack 32P controller.
