Overview
The Prolon PL-PN1-7F is a pre-wired, UL508A certified NEMA 1 control panel built with one Prolon M2000 controller running the FlexIO Controller program, which is a general purpose HVAC controller whose inputs and outputs can be individually configured for applications not covered by a dedicated Prolon program. Isolation relays on all digital outputs, overcurrent fuse protection and clearly marked terminal blocks come factory wired.
Program strategies include ON/OFF, PI loop, and direct or reverse acting output logic, output interlocks and overrides based on outside temperature and/or occupancy. The panel contains 1 Modbus RTU (RS485) node and runs stand-alone or on a Prolon network of up to 127 nodes.

Key Features
Up to 8 occupancy states
Can receive up to 8 different occupancy states from an NC2000, and outputs can act on any local input or on network data.
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.
AUTO/OFF/HAND switches
The M2000 controller includes AUTO/OFF/HAND switches, plus 5 triac digital outputs and 3 analog outputs.
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.
