Analog quantities, such as current, voltage, temperature, pressure, etc., vary continuously. Industrial production, especially continuous production process, often needs to control these physical quantities.
ABB UFC921A101 3BHE024855R0101 Control board
As an industrial control electronic device, if PLC can not control these quantities, it is a big deficiency. For this reason, PLC manufacturers have carried out a lot of development in this area. At present, not only large and medium-sized computers can carry out analog control, but also small computers can carry out such control.
ABB UFC921A101 3BHE024855R0101 Control board
PLC shall be equipped with A/D and D/A units for conversion between analog quantity and digital quantity for analog quantity control. It is also an I/O unit, but a special I/O unit.

A/D unit converts the analog quantity of external circuit into digital quantity, and then sends it to PLC. The D/A unit converts the digital quantity of PLC into analog quantity and then sends it to the external circuit.

As a special I/O unit, it still has the characteristics of anti-interference of I/O circuit, isolation of internal and external circuits, exchange of information with input/output relay (or internal relay, which is also an area of PLC working memory. ABB UFC921A101 3BHE024855R0101 Control board

A in A/D here is mostly current, or voltage, and also temperature. A in D/A is mostly voltage or current. The variation range of voltage and current is mostly 0~5V, 0~10V, 4~20mA. Some can also handle positive and negative values.

Here, D, minicomputers are mostly 8-bit binary numbers, and medium and large computers are mostly 12-bit binary numbers.

A/D and D/A have both single and multiple channels. There are many multiplexed input and output relays.
With A/D and D/A units, the remaining processing is digital, which is not difficult for PLC with information processing capability. Medium and large PLCs have stronger processing power. They can not only add, subtract, multiply and divide numbers, but also square root, interpolate, and perform floating-point operations. Some also have PID instructions, which can perform proportional, differential and integral operations on the deviation control, and then generate corresponding output. It can do almost everything that the computer can do.
