INTRODUCTION

The Field Isolation Transducer (FIT) is compatible

with DECS-400 and DECS-450 Digital Excitation

Control Systems, designated as DECS henceforth.

The FIT receives isolated operating power from the

DECS and supplies the DECS with isolated field

current and field voltage signals. An FIT is required

for each DECS unit used in an excitation system.

FITs are identified by four part numbers:

9372900100. 9372900101. 9372900104. and

9372900105.

DECS-400 Models

Part number 9372900100 identifies the FIT

assembly. Part number 9372900101 identifies the

FIT packaged for shipping and should be specified

when requesting a replacement or spare module.

Each FIT is supplied with a cable (Part number:

322900006) for connecting the FIT (connector J1) to

the DECS.
