Overview
The Prolon PL-PN1-7X is a pre-wired, UL508A certified NEMA 1 control panel built with one Prolon M2000 controller, with the controller program specified at order. Isolation relays rated 17A @ 277 VAC on all 5 digital outputs, overcurrent fuse protection and clearly marked terminal blocks come factory wired.
Available M2000 applications are BLR, CHL, FCU, FLX, HP, HPS, HYD, MUA standard, RTU and RTUS. The panel contains 1 Modbus RTU (RS485) node and runs stand-alone or on a Prolon network of up to 127 nodes.

Key Features
Any M2000 program
Built with a M2000 set up for the application you specify at order: BLR, CHL, FCU, FLX, HP, HPS, HYD, MUA standard, RTU and RTUS.
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.
Onboard diagnostic LEDs
Onboard LEDs show the state of each output, communication, power and the microprocessor for quick diagnostics.
Free Prolon Focus software
Remote monitoring and configuration with free Prolon Focus software, stand-alone or networked up to 127 nodes.
ZOT Supply is an authorized distributor of Prolon products.

Frequently Asked Questions
What is the Prolon PL-PN1-7X?
A pre-wired one controller panel built with a Prolon M2000 controller in a UL508A certified NEMA 1 enclosure, with isolation relays on all 5 digital outputs.
Which program does the PL-PN1-7X run?
The program is specified at order. M2000 applications are BLR, CHL, FCU, FLX, HP, HPS, HYD, MUA standard, RTU and RTUS; the application-specific codes are PL-PN1-7C through the matching letter in the ordering guide.
Can the controller be changed to another program later?
Yes. The M2000 keeps its full functionality, including the ability to reflash into a different controller program.
What power does the panel require?
24 VAC ±10%, 50/60 Hz, Class 2. The M2000 draws 5 VA (consumption), 40 VA (input).
