Overview
The Prolon PL-PN1-7K is a pre-wired, UL508A certified NEMA 1 control panel built with one Prolon M2000 controller running the Air Make Up Controller program, which operates a variety of make-up air units and systems. Isolation relays on all digital outputs, overcurrent fuse protection and clearly marked terminal blocks come factory wired.
Program strategies include outdoor temperature reset, building pressure control, CO2 control and lockout mode and safety limits. The panel contains 1 Modbus RTU (RS485) node and runs stand-alone or on a Prolon network of up to 127 nodes.

Key Features
Standard MUA configuration
Standard make-up air panel without the additional door hardware (selector switch, door LEDs and lockout reset button).
17A isolation relays
Every digital output is isolated by a relay rated 17A @ 277 VAC built into the panel (M2000 = 5), and the controller outputs are protected by resettable fuses.
Fused, pre-wired NEMA 1 panel
Clearly marked terminal blocks, wire management channels and a disconnect-style Slo-Blo fuse (3A @ 250 VAC) with a replacement fuse included. The panel wiring diagram is in the door, and all inputs and outputs are tested in the factory.
Reflash to another program
The M2000 keeps its full functionality, including the ability to reflash into a different controller program. Wiring diagrams are available free at proloncontrols.com.
Manual/off/auto switches
A manual/off/auto switch for each of the eight outputs of the M2000 controller.
Free Prolon Focus software
Remote monitoring and configuration with free Prolon Focus software, stand-alone or networked up to 127 nodes.

Frequently Asked Questions
What is the Prolon PL-PN1-7K?
A pre-wired one controller panel built with a Prolon M2000 controller running the Air Make Up Controller program, in a UL508A certified NEMA 1 enclosure with isolation relays on all digital outputs.
What does the air make up program control?
It operates a variety of make-up air units and systems. Strategies include outdoor temperature reset, building pressure control, CO2 control and lockout mode and safety limits.
Which inputs does the PL-PN1-7K use?
9 configurable analog inputs: zone temp, outside temp, discharge temp, proof of exhaust, fan and damper opening (dry contact), manual overrides, CO2 levels, static pressure (thermistor / dry contact / 4-20mA / 0-5 VDC).
What power does the panel require?
24 VAC ±10%, 50/60 Hz, Class 2. The M2000 draws 5 VA (consumption), 40 VA (input).
Are the outputs isolated and protected?
Yes. Every digital output is isolated by a relay rated 17A @ 277 VAC built into the panel, the triac outputs are rated 300 mA max with resettable fuses, and the panel has a disconnect-style Slo-Blo fuse (3A @ 250 VAC) with a replacement fuse included.
How does the PL-PN1-7K communicate?
Modbus RTU (RS485), up to 127 nodes, at 9600 to 115200 baud. The panel contains 1 node and is configured with free Prolon Focus software.
