Electronic universal testing machine-Electric pull main control bord

Controller introduction:

The controller adopts DSP digital control main control chip of American TI company, which gathers the top high-performance analog-to-digital conversion, communication and differential pulse output chips of world-famous chip manufactures, such as TI, ADI, CYPRES, CIRRUS, ATML, TOSHIBA, LINTER,STC, etc. The board uses a large number of tantalum capacitors instead of traditional capacitors, which greatly improves the control accuracy, long-term life and stability of the controller. After long-term market testing, it is a classic work in domestic controllers.

Controller features:

 1, force, deformation of the measurement resolution of1/3500 of the full range;

 2, sampling frequency up to 12O Hz;

 3, based on the high-end industrial control field of DSP system plat form, set measurement, control in one, more powerful function, more stable performance

 4， Adopt three closed-loop full digital control of force, deformation and displacement, and automatically switch between control rings, with a smooth transition. The control algorithm adopts the advanced neuron adaptive PID control algorithm, without complicated PID parameter setting

 5,8-way 24bitA/D high precision data acquisition channel with advanced digital filtering technology beginners can easily complete professional test tasks; more accurate, stable and reliable data acquisition;

 6,high-speed photoelectric encoder(5MHz)signal acquisition channel, can choose more output optical code signal measurement accessories; plug and play interface, convenient to expand various measurement accessories

 7. It adopts super large scale programmable digital integrated circuit design, with small volume, low power consumption, less heat generation, and more stable and reliable working characteristics
