The 24V RS485 version of the N1050 is for Modbus communication with other devices as part of a serial network, allowing integration into existing control systems including SCADA. It still functions as a standalone PID controller as per the N1050-PR, but adds remote control via RS485 and two additional relay outputs — with added USB functionality, ramp and soak programming (5 programs of 4 segments each), and a 50mA pulse output capable of driving up to 4 standard Solid State Relays. It's a proven direct replacement for West, Omron, and Eurotherm controllers, and well suited to ovens and kilns running multiple ramp and soak stages, autoclaves, machinery and OEM builds, general process equipment, heat treatment, and metal processing.
N1050 is an advanced high performance PID temperature controller featuring a vivid LCD display in a modern design package. It combines the proven robustness of NOVUS PID algorithm with a large and bright easy-to-read multicolor 11-segment LCD display with alphanumeric mnemonics and crystal clear status signaling.
Besides the PID auto-tuning capability, N1050 outputs PWM control mode through pulse or relay. It also features 5 ramp-and-soak profile programs, soft start output and timer function which complement the advanced features of the controller. With password protection, all parameters are configurable by the display menu, via USB port or optional RS485 Modbus interface.
Easy to install and maintain due to its detachable connector, N1050 offers the lowest power consumption in the market. Housed in anti-flame material, it has 48x48 mm (DIN 1/16) format and low profile front panel. Suitable for hostile environments, it complies with standard EMC regulations, providing robustness and reliability including untapped temperature applications.

Frequently Asked Questions
How does this differ from the standard N1050-PR-24V?
It adds an RS485 Modbus interface for SCADA/serial network integration, plus two additional relay outputs (3 relays total vs 1 on the base N1050-PR-24V) — otherwise the ramp & soak programming and core PID performance are the same.
Can I use this as a standalone controller without a network?
Yes — it functions as a full standalone PID controller identical to the N1050-PR-24V; RS485 is an optional extra, not a requirement.
Is there a Modbus register map available?
Yes — the Modbus Register Table above lists all readable/writable registers for integrating with a PLC or SCADA system.
Industry Applications
- Off-Grid & Mobile SCADA Integration — 12-24V supply with RS485 Modbus for remote or vehicle-mounted equipment.
- Legacy Controller Replacement — direct upgrade path from West, Omron, or Eurotherm units with comparable I/O.
- Multi-Zone Ovens & Autoclaves — networked ramp & soak control across several zones from one system.
