Digital servo controller
Various types of testing machineModel PCA-8002 multi-function M&C board
This product uses the computer PCI bus, plug-in design. Single board can be used independently, but also multiple board use, having the characteristics of plug and play, can be flexible according to the requirements of customers and manufacturers to use, and photoelectric coupling technology adopted. Board has 24 A/D conversion, high measurement accuracy. The system in the analog sensor measurement process, bridge voltage and A/D converter uses uniform reference, always stay the same.
