The ENDA ET4430 is a high-precision digital controller designed for diverse industrial temperature regulation tasks. With its clear dual-line LCD display, operators can simultaneously monitor the process value and setpoint with high visual clarity.

Core Functionality

• Precision Regulation: Implements a sophisticated PID algorithm with an automatic Self-tuning feature to optimize control parameters for different thermal loads.
• Universal Power Supply: Built-in switched-mode power supply operates reliably between 85V and 265V (AC or DC), accommodating global voltage standards.
• Input Flexibility: Users can configure the device for the most common industrial sensors, including Pt100 RTDs and multiple thermocouple types.
• Soft-Start Feature: Integrated soft-start function protects heating elements by controlling the power ramp-up phase.

Technical Specifications

• Accuracy: ±0.5% of full scale (for thermocouples) and ±0.2% (for Pt100).
• Output 1 Configuration: Factory-fixed as either Relay (8A 250V AC) or SSR Drive (12V DC 20mA).
• Output 2 Configuration: Secondary Relay output (5A 250V AC, NO contact) for alarm or auxiliary control.
• Display: 4-digit PV and 4-digit SV LCD with backlight.

Applications

• Plastic processing and injection molding equipment
• Industrial drying ovens and climate chambers
• Food and beverage sterilization systems
• Textile and chemical thermal processing
