FAQ

Which I/O devices are connectable?


If you install an EX module on an LT unit, analog input/output and thermocouple input will be allowed as well as the standard input/output as shown below.

IMPORTANT
* Internal communication between the LT unit and the EX module may experience a maximum delay of scan time +10 ms. Because the EX module (hardware) also has a delay, to calculate the actual delay time for inputs and outputs, you need to also add the EX module delay time.

The details of the EX modules are as follows.
