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.

Parts Included in Conversion Accessory

• base bracket (1)

• spring latches (2)

• 1/8 inch Pop-rivet (6)

BRACKET MOUNTING PROCEDURE

The following steps describe how to install the Foxboro conversion brackets on to the instrument.
Removal of the MODCELL 2051R instrument from the instrument housing is not necessary.

1. Remove the contents of the conversion kit from its package and examine that all parts are
present.

2. Locate the large black bracket to the bottom of the MODCELL 2051R, aligning the four 1/8
inch holes. Orient the bracket as shown in Figure 1. Insert a pop rivet into each of the four
holes and secure the bracket in place using the pop-rivet gun.

3. Stack the two top latch brackets one on top of the other so the 1/8 inch holes align. Align the
brackets to the top front two 1/8 inch holes of the MODCELL 2051R instrument. Orient the
bracket as shown in Figure 1. Secure this bracket in place with the two remaining 1/8 inch
pop-rivets.

SPEC 200 DIRECT CONNECT CABLE INSTALLATION

1. If field wiring is to be connected directly to the back of the MODCELL 2051 instrument,
proceed directly to Panel Installation. Terminate field connections describe in the I/O
instructions in IB-23C650-_._. If the intermediate installation is being employed, continue
with steps 2 through 9.

2. Remove the termination cover from the back of the MODCELL 2051.

3. Insert the termination end of the direct connect cable into the lower left termination block as
shown in Figure 2. With the cable facing down, the lowest pin of the terminator should be
inserted in terminal position NO. 2. Tighten all termination screws on the associated pins of
the terminator.

4. Dress the cable down and out the bottom of the termination assembly. Using the Tyrap
provided, secure the cable to the termination cover post as shown in Figure 2.

5. Replace the termination assembly cover and tighten in place.

6. Apply power to the MODCELL 2051R.

7. Enter the "Base Config **Menu**" (see IB-23C650-_._), select "volt" as the input type for the
process input.

8. In the "Milliamp Input **Menu**", configure the analog input for an electrical input of 0 to 5
volts (the terminator has proportionately reduced the 0 to 10 Vdc signal to 0 to 5 Vdc). In the
"Milliamp Output **Menu**", configure the control output current to 0 to 40 milliamps. The
terminator has a precision resistor on the output to generate 0-10 Vdc with a 0 to 40 mA
output current.

9. Configure other options and features in the instrument as required for the application.
