Io Configuration - NetComm NTC-220 User Manual

IO configuration

The NTC-220 Series router is equipped with a 6-way terminal block connector providing three identical
multipurpose inputs and outputs as well as a dedicated ignition input. These inputs and outputs may be
independently configured for various functions, including:
NAMUR (EN 60947-5-6 / IEC 60947-5-6) compatible proximity sensor input
Proximity sensor input for use with contact closure (open/closed) type of sensors (PIR sensors, door/window
sensors for security applications) with the input tamper detection possible (four states detected: open,
closed, short and break) using external resistors
Analogue 0V to 30V input
Digital input (the I/O voltage measured by the iMX283 LRADC and the software making decision about the
input state) with the threshold levels configurable in software
Open collector output.
Use the pull up voltage options to select the desired output voltage of the I/O pins. The pull up voltage you select
will be the same for each pin when pull up is enabled for that pin. Each pin is capable of outputting either 3.3V or
8.2V.
