Installing the Tracer™ MP503 Input/Output Module

Ordering number: 4950 0490, 4950 0590

Product overview

The Tracer MP503 input/output (I/O) module is a
field-installed device used to monitor inputs and
control binary outputs. The I/O module has four
universal inputs that can be configured as binary,
thermistor, 0–20 mA, or 0–10 Vdc. It also has four
binary outputs.

The Tracer MP503 is available in two different
versions: frame-mount (4950 0490) and metal
enclosure (4950 0590) (see Figure 1 and Figure 2 on
page 2).

The frame-mount package contains:

• A Tracer MP503 circuit board fastened to a metal
back plate

• A removable molded resin cover

The metal-enclosure package contains:

• A Tracer MP503 circuit board fastened to the back
plate of the metal enclosure

• A removable metal cover

IMPORTANT

Mount the Tracer MP503 with the cover on to avoid
damaging the circuit board during installation.

To mount the frame-mount I/O module:

1. Using the module as a template, mark the
location of the two mounting holes on the
mounting surface (Figure 3).

2. Set the module aside and drill holes for the
screws at the marked locations.

Drill holes for #10 (5 mm) screws or #10 wall
anchors. Use wall anchors if the mounting
surface is dry wall or masonry.

3. Insert wall anchors if needed.

4. Secure the module to the mounting surface with
#10 (5 mm) screws (not included).

Attach the frame-mount module securely so that it
can withstand the vibrations of associated heating,
ventilating, and air-conditioning (HVAC) equipment.

Figure 3. Mounting the Tracer MP503

To mount the metal-enclosure I/O module:

1. Remove the two cover screws and then the cover.

2. Using the enclosure as a template, mark the
location of the four mounting holes on the
mounting surface (Figure 4).

3. Set the enclosure aside and drill holes for the
screws at the marked locations.

Drill holes for #10 (5 mm) screws or #10 wall
anchors. Use wall anchors if the mounting
surface is dry wall or masonry.

4. Insert wall anchors if needed.

5. Secure the enclosure to the mounting surface
with #10 (5 mm) screws (not included).
