PQM-T20-C-A Standalone I/O Processor

PQM-T20-C-A provides many dedicated modules and function modules for various signals and applications in the industrial field, such as temperature, tension, stepper motor drive, oscilloscope, drum sequence generator signals, incremental pulse encoding signals, weighing signals and ultrasonic signals, power measurement and grid synchronisation, and PWM output. They will be various forms of field signals is very convenient to access to the PCC as the core of the digital control system, the user can be required to the application system I / O channel tens of points, hundreds of points or even thousands of points of expansion and networking.

Inside the PQM-T20-C-A module, the CPU’s data bus is separated from the I/O bus and configured with an independent I/O processor. The main CPU contains an independent time processing unit TPU (Time Processing Unit ), which handles simple or complex timing tasks at high speed without increasing the CPU load, and its reference timing frequency can be as high as 6.29MHz

The PQM-T20-C-A uses a single-task clock scanning or monitoring programme (except for certain high-grade PLCs, such as Siemens’ S7-300/400 series, Rockwell’s ControlLogix series, etc.) to handle the logic operation instructions of the programme itself and the status acquisition and refreshment of external I/O channels, with the entire application being contained in a single loop cycle.
