Electrical-pneumatic control

Configuration:
Delivery limit Pneumados
PE 6x4, max 1m
Pneumados
Wiring diagram:
Electrical pulse
generator
Compressed air
An electrical pulse generator drives a pneumatic solenoid valve. During the metering stroke, the
pneumatic solenoid valve applies compressed air to the pump; during the suction stroke, this air
volume is released into the open from the solenoid valve via the vent connection "R".
Technical data of the electrical-pneumatic control:
Via pulse generator – pulse control of PLC control or pulse generator relay with pulse duration of
approx. 250ms, e.g. flashing relay, adjustable between 0.1 and 1s, 24Vdc
Via 3/2-way solenoid valve, e.g. MHE3-M1H-3/2G-QS-6-K-525152 (order no. 1030275)
