Overview
The Prolon PL-PN2-1A-7C is a pre-wired, UL listed NEMA 1 two controller panel built with a Prolon NC2000 Network Controller with 10-Inch Touchscreen HMI and a Prolon M2000 Boiler Controller. Isolation relays rated 17A @ 277 VAC on all digital outputs, overcurrent fuse protection and clearly marked terminal blocks come factory wired.
The NC2000 connects the Prolon network to the internet, manages the occupancy schedule and outside temperature, sends email alerts and records trend logs, with a built-in 10-inch touchscreen for local setup. The M2000 Boiler Controller runs staged or modulating boiler sequences with their pumps. The panel contains 2 Modbus RTU (RS485) nodes and runs stand-alone or on a Prolon network of up to 127 nodes.

Key Features
10-inch touchscreen HMI
Built-in 10-inch touchscreen display on the panel door for local setup and monitoring of the Prolon system.
17A isolation relays
Every digital output is isolated by a relay rated 17A @ 277 VAC built into the panel (C1050 = 4, 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 wiring diagram is in the door, and all inputs and outputs are tested in the factory.
M2000: Staged or modulating boilers
Wiring configurations cover staged boilers (4 boiler stage outputs plus pumps) and modulating boilers driven from the analog outputs.
Free Prolon Focus software
Remote monitoring and configuration with free Prolon Focus software, stand-alone or networked up to 127 nodes.
