Product overview
The Tracer MP580 programmable
controller is factory-installed on Trane
Modular and T-Series Climate Changer
air handlers.
The Tracer MP581 programmable
controller is available for field installation
for a variety of heating, ventilating, and
air-conditioning (HVAC) applications.
Applications
Tracer MP580/581 controllers support a
wide variety of building control
applications, including:
• Air-handler control
• Support of the LonMark Space Comfort Controller (SCC) profile and the
Discharge Air Controller (DAC) profile
for air handlers
• Control of mechanical-room equipment, including cooling towers,
pumps, boilers, and heat exchangers
• Supervisory control of an HVAC network for mid-sized buildings
• Nearly any control process needed in
a commercial building
Product models
Several models of Tracer MP580/581
controllers are available. Tracer MP581
models are illustrated in Figure 1 on
page 5. Operator-display touch screens
are available as an option for all models.
Tracer MP580 on Trane air handlers
The Tracer MP580 controller is available
packaged with Trane Modular and
T-Series Climate Changer air handlers.
The controller is factory wired to all
sensors, actuators, valves, starters, and
other items shipped with the air handler.
Factory testing of connected points
helps minimize field commissioning
time and expense.
Frame-mounted Tracer MP581
The frame-mounted Tracer MP581
consists of a circuit board and a
termination board mounted in a twopiece modular frame assembly. This
modular design allows the circuit board
to be programmed at a different location
while installation and wiring are
completed. The frame-mounted Tracer
MP581 can be mounted in new
equipment or an existing enclosure.
Tracer MP581 in a NEMA-1 enclosure
The Tracer MP581 with enclosure
consists of the frame assembly
mounted in an enclosure compliant with
National Electrical Manufacturers
Association (NEMA) type-1 standards. A
line-to-low voltage transformer provides
power to the electronics. The enclosure
has a hinged door and plenty of room for
input and output wiring. The complete
assembly is UL-listed.
Inputs and outputs
Tracer MP580/581 controllers have the
following inputs and outputs (illustrated
in Figure 8 on page 11):
• 12 universal inputs
Dry contact binary (including pulse
accumulation), 0–20 mA, 0–10 Vdc,
linear resistance, or thermistor. Four
of the twelve inputs can be used
directly with resistance temperature
detectors (RTDs).
• Static pressure input
Specialized input for a Trane
differential pressure sensor
(5 Vdc, 0–5 in. wc).
• 6 binary outputs
12 VA at 24 Vac powered relay
contacts.
• 6 analog outputs
0–10 Vdc or 0–20 mA.
