Overview
The Watlow PM3C1FJ-AAAABAA is an EZ-ZONE PM panel mount PID temperature controller engineered for precision thermal control in industrial automation systems. This compact 1/32 DIN-sized unit combines a high-performance PID controller with universal input capability, 100–240VAC power supply, and dual outputs (4–20mA analog and mechanical relay), making it suitable for OEM equipment, process heaters, and thermal management loops.
Key Features
- Universal thermocouple and RTD input for flexible sensor compatibility
- Integrated PID controller with tuning capabilities to minimize overshoot and settling time
- Dual outputs: 4–20mA control signal and mechanical relay for on/off or proportional switching
- 1/32 DIN panel-mount form factor for space-constrained installations
- 100–240VAC single-phase input for global power compatibility
- Multiple communication options available to support industrial network integration
