Basler Electric Field Isolation Transducer, with Cable Assembly (9372900101)

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.

DECS-450 Models

Part number 9372900104 identifies the FIT

assembly. Part Number 9372900105 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:

9372900021) for connecting the FIT (connector J1) to

the DECS.

For EMC-compliant installations, use FIT

9372900104 or 9372900105. and Cable 9372900021

with the DECS-450.

FUNCTIONAL DESCRIPTION

Field sensing current is supplied to the module by a

user-supplied current shunt with an output rating of

50 mVdc or 100 mVdc. The field current sensing

input accepts up to 300% of the nominal current

range. The field current signal is converted into a

voltage signal from 2 to 9.5 Vdc and sent to the

DECS through connector J1.

Field sensing voltage is supplied directly from the

field to the module. The FIT accepts one of five field

voltage ranges: 63 Vdc, 125 Vdc, 250 Vdc, 375 Vdc,

or 625 Vdc. The field voltage sensing input accepts

up to 300% of the nominal voltage range. The field

voltage signal is low-pass filtered, converted into a

voltage signal from 0.9 to 9.1 Vdc, and sent to the

DECS through connector J1.
