3.3 Input and Output Circuits
This subsection describes the input and output circuits of including2N SmartCOM
®
main use, control and location.
Tip
2N SmartCOM
®
is equipped with reliable terminals for easier and
faster connection.
Input Circuits
2N SmartCOM
®
is equipped with two inputs, which are mutually galvanically
connected with the GND reference point (have a common GROUND). Remember to
keep the parameters specified in the Technical Parameters at the end of this manual.
The input circuits can work in three modes – voltage, current or logical levels – as
configured.
Voltage measurement
Voltage can be measured in the range between 0 and 10V DC. Make sure that the 2N
®
jumpers are set as shown in Figure 3.3 before using this mode. Use the SmartCOM
AT commands listed in (ADC) for reading and calibration.Subs. 4.2
Current measurement
Electric current can be measured in the range between 4 and 20 mA. Make sure that
the jumpers are set as shown in Figure 3.3 before using this mode. 2N SmartCOM
®
Use the AT commands listed in (ADC) for reading and calibration.Subs. 4.2
Logical level monitoring
You can monitor the logical levels of voltage and current signals. Use other commands
that those intended for classic measurements and define the threshold levels. Again,
use the AT commands for reading values on input circuits.
Pulse counting on S0 inputs
Make sure that the jumpers are set as shown in the figure below for pulse counting on
S0 inputs. The S0 input has thus a power supply of its own and can be connected
directly to the switch or relay contacts. The counter is disabled by default and has to be
enabled using the AT commands included in .Subs. 4.2
The figures below show the location of jumpers for current/voltage input switching.
Release the screws and remove the case cover to get access to the jumpers. See the
figure to the right for correct setting.
