The Allen-Bradley 1747-L20G PLC is designed with an integrated power supply and a fixed I/O configuration, featuring a processor with a 1K instruction capacity. Operating between 47-63 Hz, it is powered by a 24V DC line and incorporates a DC transistor source output. The unit supports a high-speed counter function, capable of calculating up to 8 kHz and offering a selectable jumper filter for input 0, which can function either as a standard input or a high-speed counter. To minimize noise interference, the use of shielded cables is recommended, and it is crucial to power down the controller when handling memory modules to avoid damage and processor errors.
