3Note that this is not a floating input. +28 VDC must be applied to both PWR_H and +28 VDC Return to both PWR_L inputs.

E 4.2.3 DC ANALOG INPUTS

Unless otherwise specified, Input Signal accuracy is1% linearity +0.1% full scale offset.

E 4.2.3.3 LOCALIZER DEVIATION OR LOW LEVEL GLIDESLOPE VALIDITY

This input can be configured as either a low level glideslope valid, or as a localizer deviation input. Installations that only have the low level validity signal for glideslope can not activate the analog localizer input. See section 5.3.9 for more information.
