sp5604 
SCADAPack 5604 I/O module 
Description 
The sp5604 I/O module is comprised of four different types of I/O channels. The 
SCADAPack 5604 I/O hardware contains ten analog inputs, two analog outputs, thirty-five 
digital inputs and thirty-six digital outputs. Each of these types of I/O is represented as a sub 
module in the sp5602 I/O module. These sub modules are named AIN for analog input I/O 
channels, AOUT for analog output I/O channels, DIN for digital input I/O channels and DOUT 
for digital output I/O channels. 
The AIN sub-module provides eight I/O channels for the analog input data from the 
SCADAPack 5604 I/O hardware. Data for each of the ten I/O channels may be connected to 
user-defined variables with the I/O connection editor. Connected variables are updated 
continuously with data from the SCADAPack 5604 I/O hardware. 
  Analog input channels 0 to 7 provide eight external analog inputs (0-10V or 0-40mA) 
  Analog input channel 8 provides an external analog input for battery monitoring (0 to 
32.768V) 
  Analog input channel 9 provides an internal analog input for DC/DC converter 
monitoring. 
The AOUT sub-module provides two I/O channels for the analog output data for the 
SCADAPack 5604 I/O hardware. Data for each of the I/O channels may be connected to 
user-defined variables with the I/O connection editor. The SCADAPack 5604 I/O hardware 
analog outputs are updated continuously with data read from the variables. 
The DIN sub-module provides thirty-five I/O channels for the digital input data from the 
SCADAPack 5604 I/O hardware.  
The sp5604 I/O Module provides thirty-two universal digital inputs or outputs. The inputs are 
for use with dry contacts such as switches and relay contacts.  
  These are defined as digital input channels 0 to 31. 
0 = contact open (LED off) 
1 = contact closed (LED on) 
The sp5604 I/O module also provides three internal digital inputs. 
  Digital input channel 32 returns the DC/DC converter status.  
0 = DC/DC converter off 
1 = DC/DC converter on 
  Digital input channel 33 returns the DC/DC converter over current status. 
0 = Over current not detected 
1 = Over current detected 
  Digital output channel 34 returns the digital output mismatch status. 
0 = No mismatch 
1 = One or more digital outputs mismatch 
Data for each of the I/O channels may be connected to user-defined variables with the I/O 
connection editor. Connected variables are updated continuously with data from the 
SCADAPack sp5604 I/O hardware. 
The DOUT sub-module module provides thirty-six I/O channels for the digital outputs of the 
SCADAPack 5604 I/O hardware.
