PI1A position indicator

Part no.: ART16399
The PI1A position indicator product is intended for indicating the position of the trim servo, flaps and other equipment of UL aircraft, which transmits this position using a 3-wire potentiometer. It has a dimming input that behaves according to the relevant product variant. The PI1A variant has a continuous brightness control in the range of 5..100%. When dimming is off (DIM=GND or not connected), the product automatically switches to full brightness. The product recognizes 9 working positions and is also able to indicate fault conditions of position measurement (dropped, shorted wire). Horizontal or vertical positions can be used for signaling. Therefore, both label variants are supplied with the product. The subject of the order is one piece of the position indicator product.
