Section 1

INTRODUCTION

1.1 DESCRIPTION

The 21V Power Supply is a continuous mode boost switching type power supply. It is based
upon a low power, low noise circuit that produces 21 Volts from a 12 Volt input. Fuse F1
(500 mA Slow Blow) is provided to protect the TeleFlow/TeleRTU power source from failures
within 21V Power Supply. Fuse F2 (350 mA Fast Blow) is provided to protect the 21V Power
Supply circuitry from short circuits on an output.

Power shutdown is not an option with this unit since it employs a Boost circuit; therefore,
the 21V Power Supply must be powered continuously. 21V Power Supplies receive input
power (12V) from connector TB3 of the Power Distribution Board. The Power Distribution
Board is required because of CPU Board connector wiring capacity restrictions, i.e., the
connectors only accommodate up to #14 AWG wire.

Four (4) mounting holes (one in each corner) are provided to accommodate a #4 mounting
screw. However, these units are typically Snap Track mounted on a Dual PCB Mounting
Bracket (see Figure 2)).

The 21V Power Supply is mainly used in conjunction with Temperature and Pressure
Transmitters which require a higher than +12V but lower than 21.4V (± .8V) input supply to
operate.

INSTALLATION & SERVICE

2.1 REMOVAL/REPLACEMENT & INSTALLATION OF THE

21V POWER SUPPLY OPTION

2.1.1 Removal/Replacement of the 21V Power Supply Option

An installed 21V Power Supply option will contain the following parts:

1. 21V Power Supply Board (with removable Terminal Blocks)

2. Dual PCB Mounting Bracket

3. 2 Snap Tracks

4. Power Distribution Board (with removable Terminal Blocks)

5. Two #8-32 x ¼” SEM Screws

6. Two #8-32 x 3/8” Pan Head Screws and Two #7-32 Elastic Locking Nuts

Figure 2 - 21V Power Supply Option Major Components

TeleFlow Plus or TeleRTU Plus with Power Distribution Board

PIP-353021VS Page 2 21V Power Supply Board

To remove the optional 21V Power Supply, follow steps 1 through 4 below. To replace the
21V Power Supply follow steps 2 and 3 below in reverse order, installing rather than
removing the item in question and then perform step 4.

1. Open the Instrument Front Cover (Door).

2. Unplug the removable Terminal Blocks (with wiring harnesses installed) from the

optional 21V Power Supply Board.

3. Slide the 21V Power Supply Board toward the front of the unit and out of the Snap

Track.

Note: If a replacement 21V Power Supply Board is available follow steps 2

through 3 in reverse order, installing rather than removing the item in
question.

4. Close and secure the Door.

Figure 3 - Bottom View of TeleRTU Plus (Similar to TeleFlow Plus)

2.1.2 Installation of the 21V Power Supply Option

1. Open the Instrument Front Cover.

2. If the unit in question already contains a Power Distribution Board, but only has one

Snap Track, the other Snap Track will have to be installed. This will require removal of
the two (2) #8-32x3/8” Pan Head Screws and the two (2) #8-32 Elastic locking Nuts
which secure the Power Distribution Board’s Snap Track to the Dual PCB Mounting
Bracket. Secure the second Snap Track to the Dual PCB Mounting Bracket as shown in
Figure 2 using two (2) #8-32 x 3/8” Pan Head Screws and two (2) #8-32 Elastic Locking
Nuts. Slide the Power Distribution Board into the Snap Track as illustrated in Figure 2.

PIP-353021VS Page 3 21V Power Supply Board

3. Connect power wiring (14 AWG) between the Power Distribution Board (PDB) and the

21V Power Supply Board’s input terminals and between the 21V Power Supply’s output
terminals and the appropriate terminals on the Low Power I/O Expansion Board
(LPI/OEB) (see Table 1 and Figure 4). Route field wiring cable(s) (14 AWG) associated
with the item to be powered, e.g., a 3508B Transmitter into the TeleFlow Plus or
TeleRTU Plus through a ¾” conduit fitting (user supplied) on the bottom of the enclosure
(see Figure 3). Connect Transmitter wiring to the appropriate LPI/OEB terminals (see
Figure 4).

4. Close and Secure the Instrument Front Cover.

2.2 FIELD WIRING

The device uses compression-type terminals that accommodate up to #14 AWG wire. A
connection is made by inserting the bared end (1/4 inch Max.) into the clamp beneath the
screw and then securing the screw. Insert the bared end fully to prevent short circuits.

Allow some slack in the wires when making terminal connections. The slack makes the
connections more manageable and minimizes mechanical strain on the printed circuit
boards and harnesses.

2.2.1 Terminal Connections

21V Power Supply Boards contain two terminal blocks that accommodate interface con­nections to the 3530-20B or 3530-25B, power and field wiring connections. TB1 is a three­position terminal block that provides input power connection from the Power Distribution
Board. Four-position Terminal Block (TB2) provides +21V power and ground to the Low
Power I/O Expansion Board (LPI/OEB) (see PIP-EXPI/OTF) which will power external
devices requiring 21V power such as 3508B Transmitters.

and 12VGND terminals of the 21V Power Supply Board. The input voltage range is
+10.8Vdcc to +16Vdc.

The +21V Power Supply Option is typically powered from the 3530’s power source (battery).
Because of power distribution restrictions (CPU Board connector wiring capacity), power
must be routed through a Power Distribution Board (see Figures 2 & 4). Power Distribution
Boards are mounted to the 3530 in question using a Snap Track and Dual PCB Mounting
