SOLENOID VALVE DRIVER OF HIGH SPEED MULTI-CHANNEL

摘要

Disclosed is a high-speed and multi-channel driving apparatus for a solenoid valve which can simultaneously drive solenoid valves with various driving methods at one place. The high-speed and multi-channel driving apparatus for a solenoid valve comprises a signal input terminal to receive a pulse-type driving signal of a solenoid valve in multiple channels; a waveform standardizing unit which standardizes a waveform of the driving signal of a solenoid valve outputted to each channel from the signal input terminal; a voltage selector which selects and outputs one of the multiple direct current voltages outputted by a power supply which outputs multiple direct current voltages; a solenoid valve driving unit which simultaneously drives multiple solenoid valves to apply the voltage selected by the voltage selector according to the driving signal of a solenoid valve outputted to multiple channels at the waveform standardizing unit to a driving voltage of a solenoid valve; and a driving signal output terminal which outputs the driving signal of a solenoid valve to multiple channels according to driving of the solenoid valve driving unit.
