The ADN601 is a valve amplifier for actuation of two proportional valves, primarily in mobile driven machines
The device can be operated at supply voltages from 11 to 28V dc, changeover from 24V supplies to 12V operating voltage occurs automatically by means of the built-in supply-voltage monitor
Switchover occurs when voltage falls below 16V
Device is normally accommodated in a plastic or metal housing
Protection against overcurrent is provided by means of a built-in resettable fuse (PTC thermistor)
Connection is accomplished via two 10-pole spring terminal strips, one earthing (grounding) terminal being available for screening of each of the two cables
Actuation of the valve is effected primarily by means of a joystick, input voltage being 0.5V—2.5V—4.5V 2.5V (zero point)
Parameter setting is accomplished via a coded rotary switch in combination with a button, a built-in potentiometer and a LED
