Overview

The Prolon PL-PN2-1B-7N is a pre-wired, UL listed NEMA 1 two controller panel built with a Prolon NC2000 Network Controller (No HMI) and a Prolon M2000 Single-Zone Rooftop 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. The M2000 Single-Zone Rooftop Controller operates a single-zone rooftop or other mechanical HVAC system from a Prolon digital temperature sensor, using PI control loops. The panel contains 2 Modbus RTU (RS485) nodes and runs stand-alone or on a Prolon network of up to 127 nodes.

Key Features

NC2000 network controller

The NC2000 connects the Prolon system to the internet over Modbus TCP/IP, with schedules, email alerts and trend logs.

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: Local digital sensor

The INT port connects a Prolon digital temperature sensor, so the rooftop runs from local demand.

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-PN2-1B-7N?

A pre-wired two controller panel built with a Prolon NC2000 Network Controller (No HMI) and a Prolon M2000 Single-Zone Rooftop Controller, in a UL listed NEMA 1 enclosure with 17A isolation relays on all digital outputs.

What does the M2000 single-zone rooftop program control?

It operates a single-zone rooftop or other mechanical HVAC system from a Prolon digital temperature sensor, using PI control loops. Strategies include bypass or VFD and outside air damper control, CO2 levels and schedule, unoccupied mode, morning warm-up and supply air pre-heating.

What power does the panel require?

24 VAC ±10%, 50/60 Hz, Class 2; the NC2000 without HMI draws 5 VA and 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, and the panel has a disconnect-style Slo-Blo fuse (3A @ 250 VAC) with a replacement fuse included.

What size is the PL-PN2-1B-7N panel?

16.25 in. W x 20.25 in. H x 6.25 in. D (413 mm W x 514 mm H x 159 mm D), and it weighs 38 lbs (17.25 kg).

How does the NC2000 connect to a network?

Modbus TCP/IP with a static IP address or DHCP, USB and Ethernet, plus Modbus RTU (RS485) with 1 input port and 1 output port for up to 127 nodes.
