Description
The module can be used for interface conversion between PLC and frequency converter or matching control of interface between motion control card and frequency converter..Input pulse level of 5V 12V 24V can be input directly without string resistance.But the input signal frequency, to maintain more than 0.5 seconds, the output current is 5mA..The optical isolate is used to ensure the anti-interference ability of the signal input..Input pulse level of 5V 12V 24V can be input directly without string resistance.But the input signal frequency, to maintain more than 0.5 seconds, the output current is 5mA..The multi-coil potentiometer on the board is used to calibrate the corresponding relationship between frequency and voltage..The 0-3KHz frequency pulse signal is converted into a 0-10V analog voltage signal by this module.
