Electronic control CPU program board module

PLC is widely used in hydraulic machinery, in the connection of the solenoid valve, the usual practice is to use relay transfer. Because the contact of the relay is mechanical, there are fatal defects such as long switching time and short mechanical contact life (usually 1 million times), especially if it cannot meet the requirements of frequent and fast on-off.

The FD***0AA0 switching output amplifier board can convert 0.3A, 0.5A or 0.*5A transistor output to *0A transistor output, directly connected to the DC*4V solenoid valve. It has the characteristics of no mechanical contact, long life, fast switching, etc. And short circuit, overcurrent, overvoltage and other protection! There are two rows of indicators on the magnifying board, the upper row is the signal indicator, the lower row is the output signal indicator, you can clearly know the and output of the signal.
