Introduction
Some of the general demands to an up-to-date process controller for automation industry are
always high flexibility, combined with easy and simple operability.
Many applications require two separate analogue inputs for use with single or combined
operation.
Also it may be important to display and evaluate both, linear and non-linear analogue inputs at
an acceptable accuracy, which requires programmable linearization functions.
Process controllers of series AX 345 - 348 have been designed for this kind of requirements.
Model AX 345 provides display function only.
Model AX 346 provides additional analogue o/-10 volts and 0/4 - 20 mA
(a separate manual is available for the AX346 model)
Model AX347 provides two additional Preselections with Optocoupler outputs
Model AX 348 provides additional serial communication via RS232 / RS485 interface
All other functions within this controller family are fully similar.
The present operating instructions are valid for models AX 345, AX347 and AX 348 only.
Separate operating instructions are available for model AX 346
