PI1B position indicator

Part no.: ART10904
The PI1B 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 PI1A, PI1B and PI1C product variants (smooth regulation and maximum brightness at 100 or 5% and discrete regulation). The product recognizes 9 working positions and is also able to indicate failure states of the position measurement. Horizontal and vertical position of the product can be used for signaling, and a label with a description on the front of the product corresponds to this.
