Programmable logic controllers (PLCs) are an essential part of the automation sector, particularly factory automation. PLCs are classified as voltage and current inputs and convert real-world signals ...

A key subsystem in a programmable logic controller is the analog input module, which provides a high-precision front end to measure a wide variety of sensors. In many cases, however, the amplifier ...

In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...

The MAQ20-BRDG1 strain gage module has four input channels and can interface to full, half, and quarter bridge sensors using four-wire or six-wire connections. All channels are individually ...

The new M-SENS2 module is compatible with the previous M-SENS and provides the same type and number of measurement ranges. By adding a higher internal sample rate and the newly designed 500 Hz ...

The analog input of an Espressif ESP32 doesn't seem very reactive in the very first part of its allowed range, with a lack of response, and a non-linearity in the whole range, consequently. The aim of ...
