ss4202ds
SCADASense 4202 DS I/O
Description
The ss4202ds I/O is used for the SCADASense 4202 DS controller. This IO module
comprises three different types of I/O channels: analog, counter, and digital I/O.
The SCADASense 4202 DS hardware contains five analog and counter inputs, a digital
input, and two digital outputs. Each of these types of I/O is represented as a sub module in
the ss4202ds I/O module. These sub modules are named AIN for analog input channels,
DIN for digital input channels, and DOUT for digital output channels.
The AIN sub-module provides three I/O channels for the analog and counter input data from
the transmitter I/O hardware.
 Channels 1 and 2 are the analog inputs
 Channel 3 is the input voltage to the controller.
 Channels 4 and 5 are the counter inputs
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
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 two channels for the digital output data for the controller I/O
hardware. Data for the I/O channel may be connected to user-defined variables with the I/O
connection editor. The digital outputs are updated continuously with data read from the
variable.
