4.2.5 Setting Analog I/O Terminal (TBAIO)
The controller has two analog I/O terminals that can be set to voltage mode or current mode. It can
output voltage/current through an external device operated using analog I/O or receive signals from
sensors outputting analog voltage/current.
To ensure maximum input accuracy, observe the following:
•
Use shielded or twisted pair cables.
•
Connect the cable shield to the ground terminal inside the controller.
•
Current signals are relatively less sensitive to interference, so use devices operating in current
mode for analog I/O terminals. Current/voltage input modes can be set with the software.
The electrical specifications of the analog I/O terminal are as follows:
