4.2.5 Power Supply Calculations
4.2.5.1 SCADAPack P4
As illustrated in section 4.2.1-Recommended AC Power Supply Configuration the 5232 controller
board may be powering a 5601 I/O module as well as other 5000 Series modules.
The following table shows current requirements of the controller board and the 5601 I/O modules:
5V Current (mA) 24V Current (mA)
5232Controller Board
500 0
5601 I/O Module
20 + 40mA/relay 20 + 20mA/analog input
Analog Outputs
10 15 + 20mA/output
In the following example, a SCADAPack P4 with a 5232 Controller board, a 5601 I/O module with
analog outputs is powered using the Recommended AC Setup. Using this setup, 24V is available
across the DC PWR terminals on connector P3 of the controller board to power the integrated I/O
board. This 24V power must be available for both analog outputs and all analog inputs that require
power. In this example, both analog outputs and only 4 of the 8 analog inputs are being used.
Further assume all 12 digital output relays will be on with LEDs enabled. The minimum current
requirement for each module on the SCADAPack P4 is given in the table below.
