Expert Application FAQ

What sensors can I connect to the 6ES7234-4HE32-0XB0 inputs?

You can connect pressure transmitters (4-20mA), potentiometers (±10V), load cells (with signal conditioner), and other voltage/current output sensors.

Can I mix voltage and current signals on the same module?

Yes. Each of the four input channels can be individually configured in the software for either voltage or current measurement.

What devices can the analog outputs control?

The outputs can control variable frequency drives (VFDs), proportional valves, chart recorders, or any device that accepts a 0-20mA or ±10V control signal.

How do I handle the 4-20mA "live zero" with this module?

The module is designed for it. When you select the 4-20mA range, a measured 4mA corresponds to the digital value 0, and 20mA corresponds to the maximum value.

What is the "smoothing" function used for?

Smoothing filters out electrical noise from the signal. Use "Low" for fast-changing signals and "High" for very stable, slow-changing signals like temperature.
