IN502, Air Flow Controller

IN502-44 and IN502-45 are flow controllers for clean, dry compressed air that can adjust the flow rate automatically in response to an analog voltage or current signal.  Control is linear and stepless within the rated flow ranges offered.  When power is off, the controller can either stop flow or keep the flow rate unchanged depending on model selection.  Features include 1/2 metric ports, a 3-screen 3-color display, raised rubber setting buttons and an M12 cable connector.  The main screen will display current flow rate.  The sub screens can display the command value, outlet pressure, min and max values, or a user-given line name.  IO-Link and analog switch outputs are offered.  Fluid temperature is available via IO-Link.  The controller offers an IP65 rating for dusty or wet environments.
