Programmable logic controller (PLC for short) refers to a new industrial control device based on computer technology. In the draft PLC standard issued by the International Electrical Commission in 1987, PLC was defined as follows: “PLC is an electronic device specially designed for digital operation in industrial environment. It uses programmable memory to store instructions for logic operation, sequential operation, timing, counting and arithmetic operation, and can control various types of machinery or production processes through digital or analog input and output The industrial control system forms a whole and is designed based on the principle of easy expansion of its functions. “

The Horner Millivolt Input Modules (HE693ADC406 / 409) permit DC millivolt-level signals to be connected to the PLC directly without processing external signals (transducers, transmitters, etc.). The module processes analog and digital signals and millivolt values are written to the PLC %AI input table with 14-bit resolution. The module has 4 channels and an input range that is selectable from +/-25mVdc, +/-50mVdc, and +/-100mVdc. The configuration software or a Hand-Held Programmer (HHP) allow an input range to be selected. Selectable digital filtering can aid by providing a steady input signal in a loud environment. Field wiring is made to a removable 20-pin terminal strip.
