The Autonics TM4-N2RB Temperature Controller is engineered for advanced process control, offering 4-channel synchronous PID regulation with a rapid 100ms sampling cycle. Designed to operate on a stable 24VDC ±10% supply and consuming ≤5W of power, it ensures energy efficiency in demanding automation environments. Engineers can select from ON/OFF, P, PI, PD, and PID control modes, providing flexibility for a wide range of heating, cooling, and hybrid applications. The unit supports control outputs up to 250VAC 3A and 30VDC 3A, making it compatible with industrial relays, actuators, and solid-state devices.
Communication is simplified through RS485 with Modbus ASCII/RTU, ensuring seamless integration into PLCs, HMIs, and distributed control systems. Adjustable parameters such as proportional band (0.1–999.9℃), integral and derivative time (0–9999 sec), and hysteresis (0.1–100℃) enable fine tuning for stable process control. Built with double insulation and tested for 1kV dielectric strength, the controller ensures operator safety and long-term durability. The rugged construction supports continuous operation in ambient conditions of -10°C to 50°C and 35–85% RH, ensuring stable performance in Indian manufacturing plants, ovens, and cleanroom facilities. With its compact size of only 239g, the TM4-N2RB is both space-saving and highly reliable
Practical applications of the Autonics TM4-N2RB Modular Multi-Channel PID Temperature Controller include multi-zone temperature regulation in plastics molding, SMT reflow ovens, chemical batch processing, and food packaging lines. Its modular, non-display design allows easy integration into scalable panels, making it ideal for OEMs and system integrators building large automation frameworks. Maintenance engineers benefit from the controller’s robust insulation, fast response, and low power consumption, while operators value the precise PID tuning that minimizes process variation.
For engineering students and training centers, this model provides a real-world example of how synchronized temperature control improves both efficiency and quality in industrial automation. Its balance of performance, safety, and communication compatibility demonstrates why Autonics Temperature Controllers are trusted across industries.
