ss4203dr
SCADASense 4203 DR
Description
The ss4203dr I/O is used with a SCADASense 4203 DR controller equipped with a digital
output. The I/O boards on these SCADASense controllers contain three analog and counter
inputs, a digital input, a digital output, and one analog output. Each of these types of I/O is
represented as a sub module in the ss4203dr I/O module. These sub modules are named
AIN for analog input channels, DIN for digital input channels, DOUT for digital output
channels, and AOUT for analog output channels.
The AIN sub-module provides three I/O channels for the analog and counter input data from
the I/O hardware.
 Channel 1 is the input voltage applied to the controller.
 Channels 2 and 3 are for the controller counter inputs
Data for each of the three 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
controller I/O hardware.
The DIN sub-module provides one channel for the digital input data from the controller I/O
hardware. Data for the I/O channel may be connected to a user-defined variable with the I/O
connection editor. Connected variables are updated continuously with data from the
controller I/O hardware.
The DOUT sub-module provides one channel for the digital output data from the controller
I/O hardware. Data for the I/O channel may be connected to a user-defined variable with the
I/O connection editor. The digital output is updated continuously with data read from the
variable.
The AOUT sub-module module provides one channel for the analog output of the controller.
Data for the channel may be connected to a user-defined variable with the I/O connection
editor. The analog output is updated continuously with data read from the variable.
