SDVC311 Series Digital FM Vibration Feed Controller is a compact general-purpose FM
output controller that provides unique performance using the latest
electronic technology and careful design. its special features include:
The output frequency range covers 5.0Hz to 400.0Hz with 0.1Hz accuracy
* Brake function to quickly stop the vibratory feeder by shifting the current phase by 180�° during the soft-stop process. Intelligent photoelectric ports support photo sensors, NPN, or PNP switch sensors.
*Switch sensor port supports NPN, PNP, or auto-adaptive type.
The control output port supports NPN, PNP, or push-pull output mode.
Complete protection functions include main output short-circuit protection, overcurrent protection, overheat protection, undervoltage/overvoltage protection, control output shor+-circuit protection, 24V output short-circuit protection, and speed regulation 5V output short-circuit protection.

Compared with the SDVC311 controller, the SDVC311 series has greatly improved performance. mainly includes:
*The output frequency range is widened from 40.0Hz~400.0Hz to 5.0HZ~400.0Hz.
The maximum on/off delay time is increased from 20.0 s to 99.9 s.
Added the function of soft shutdown, which can be set to 0.0~10.0 s to stop the vibration of the vibratory feeder slowly.
* Added braking function, you can set 0~100 braking cycles to quickly stop the vibration of the vibrating disc.
Intelligent photoelectric sensor port adds PNP sensor support.
The Switch Sensor port when the material is full has been upgraded from NPN and PNP to software-settable, and automatic mode is provided.
The control output port is upgraded from NPN output to three types of NPN, PNP and push-pull can be set.
Added control output port on/off delay, which can be set from 0.0 to 99.9 s.
Added control output mode, you can set delay mode and hold mode. Added measurement function, which can monitor temperature, bus voltage, output current, remote speed control pot voltage, intelligent photoelectric sensor port voltage, switch sensor port voltage, DC control output port voltage and+24V power voltage.
