Conversion Instructions for
Foxboro SPEC 200 Conversion Accessory to MODCELL 2051R
Accessory Part Numbers: 2051FZ10000A, 2051FZ10001A
INTRODUCTION
This MODCELL 2051F conversion accessory allows a MODCELL 2051R to fit into the Foxboro SPEC
200 instrument shelf. Depending on the kit purchased, a MODCELL 2051R may replace all elements of
the SPEC 200 loop including; input, output, alarm, linearization cards, etc., or, replace only the display
and control card elements (intermediate installation). Intermediate installation does not require relocation
of field wiring and front panel change out will be little time if instrument setup and configuration is done
prior to panel installation.
If field wiring and input/output cards are to be retained in the Foxboro Nest, the direct connect cable
option must be used. If field wiring connections are to be made at the back of the MODCELL 2051R
controller, the direct connect cable is not required.
