Specifications from the Prolon Network Controller (PL-NC2000) datasheet REV 7.3.0 (PL-DATA-NC2000-C/F-EN), reviewed 2026-09-25.
A Modbus TCP/IP to serial converter allows remote configuration of a Prolon network, while the RS485 side connects to Prolon controllers on a Modbus RTU network of up to 127 nodes. A local PC connects over USB or RS485, and trend logs are saved to a standard SD card.
Best For
- Remote configuration of a Prolon controller network over Ethernet
- Central occupancy scheduling distributed to every Prolon controller on the network
- Sharing one outside temperature reading across the network
- Email alerting and trend logging for Prolon controllers
Warranty
Key Features
Modbus TCP/IP to Serial Converter
Connects a Prolon RS485 network to Ethernet for remote configuration, with a static IP address or DHCP.
16 Weekly Schedules and Annual Calendars
An internal clock runs up to 16 configurable weekly schedules and annual calendars, with automated adjustment for daylight savings time.
Shared Outside Temperature
Shares outside temperature data between devices on the Prolon network.
Email Alerts
Polls devices and sends email alerts based on user-configurable conditions.
100 Trend Logs on SD Card
Records up to 100 trend logs at the same time, saved onto a standard SD card.
10-Day Timekeeping
A 0.5 F super-capacitor keeps precise time for 10 days without electricity and recharges in a matter of seconds.

Frequently Asked Questions
What does the Prolon PL-NC2000 do?
The PL-NC2000 is the communication interface to a Prolon network over the internet or USB. It manages the occupancy schedule and outside temperature readings, distributes them to Prolon controllers on the network, sends email alerts on user-selectable conditions, and records trend logs.
Which communication protocols does the PL-NC2000 use?
Modbus TCP/IP on the Ethernet side, with a static IP address or DHCP, and Modbus RTU over RS485 on the controller side, with 1 input port and 1 output port. A USB port provides a local PC connection.
How many devices can the PL-NC2000 network support?
The Modbus RTU (RS485) network supports up to 127 nodes.
How many schedules can the PL-NC2000 hold?
Up to 16 configurable weekly schedules plus annual calendars, with automated adjustment for daylight savings time.
What SD card does the PL-NC2000 accept?
Standard size SD cards only, SDSC or SDHC, formatted FAT16 or FAT32. The controller can record up to 100 trend logs at the same time onto the card.
Does the PL-NC2000 keep time during a power outage?
Yes. A 0.5 F super-capacitor keeps precise time for 10 days without electricity and recharges in a matter of seconds.
What power does the PL-NC2000 need?
24 VAC ±10%, 50/60 Hz, Class 2, with a maximum draw of 5 VA.
