Introduction

The EAM121 is an interface module which accepts a nominal 0V DC input signal with a range of +/- 3V DC and outputs a nominal 5V DC across a galvanic isolated barrier. Typical usage is for signal conversion of the DC output signal from a Woodward load sharing or synchronizing system across an isolated barrier to operate a GAC governor system. The power to operate this interface comes from the output side (GAC) and is nominally 24V DC.
