sp350
SCADAPack 350 I/O
Description
The sp350 I/O module is comprised of four different types of I/O channels. The SCADAPack
350 I/O hardware contains eight analog inputs, two analog outputs, thirteen digital inputs and
eleven digital outputs. Each of these types of I/O is represented as a sub module in the
sp350 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 350 I/O hardware. Data for each of the eight 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 350 I/O hardware.
 Analog input channels 0 to 4 provide five external analog inputs (0-10V or 0-40mA,
jumper selectable)
 Analog input channel 5 provides an external analog input for battery monitoring (0 to
32.768V)
 Analog input channel 6 provides an internal analog input for DC/DC converter
monitoring.
 Analog input channel 7 provides an internal analog input for internal use.
The AOUT sub-module provides two I/O channels for the analog output data from the
SCADAPack 350 I/O optional analog output module. 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 350 I/O hardware.
The DIN sub-module provides thirteen I/O channels for the digital input data from the
SCADAPack 350 I/O hardware.
The SCADAPack 350 I/O hardware provides eight 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 7.
0 = contact open (LED off)
1 = contact closed (LED on)
The SCADAPack 350 I/O hardware also provides five internal digital inputs.
 Digital input channel 8 returns the VLOOP output status.
0 = off
1 = on
 Digital input channel 9 returns the DC/DC converter status. This bit reports the true
status of the DC/DC converter. If over-current causes the converter to be turned off, this
bit will clear.
0 = off
1 = on
