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.
