Product Short Description
Product Name: Deltat ACC-36E Digital Temperature Controller
Product Introduction: The ACC-36E is a compact, microprocessor-based single-loop temperature controller manufactured by Deltat Controls Ltd (UK). It is designed for precise temperature regulation in industrial ovens, furnaces, heaters, and packaging equipment. The unit supports multiple thermocouple and RTD input types and provides on/off, PID, and time-proportional control outputs.
Description
Technical Specifications:
- Input Type: K, J, T, E, S, R, B, N thermocouples; Pt100, Pt1000 RTDs
- Control Output: Relay (SPDT), SSR drive (voltage pulse), 4–20 mA
- Control Mode: On/Off, PID, Time-Proportional
- Power Supply: 85–265 VAC / 24 VDC
- Accuracy: ±0.1% of reading + 1°C (typical)
- Resolution: 0.1°C
- Sampling Rate: 4 readings per second
- Operating Temperature: 0°C to +50°C
- Dimensions: 96 × 48 × 78 mm (1/8 DIN)
Functional Features:
- Auto-tuning PID algorithm
- Programmable alarm setpoints (high/low)
- Remote setpoint via 4–20 mA or digital input
- Event logging capability
- Autotune function for rapid commissioning
Performance Parameters:
- Repeatability: ±0.2°C
- Response Time: <1 second (typical)
- Ambient Influence: <0.05% FS per °C
- Relay Rating: 16 A resistive, 3 A inductive (250 VAC)
Material Composition:
- Housing: ABS flame-retardant plastic (UL94 V-0)
- Front Panel: Polycarbonate with membrane keypad
- Terminal Block: Screw-type phosphor bronze
Structural Features: 1/8 DIN panel-mount format with snap-in rear clip mounting.
Working Principle: The controller reads the sensor input via a 24-bit ADC, compares it against the setpoint, and computes the control output using the selected algorithm (PID or on/off). The output drives a relay, SSR, or current loop to modulate the heating element.
Key Advantages:
- Auto-tune eliminates manual PID setting
- Universal input accepts all major thermocouple and RTD types
- Compact 1/8 DIN saves panel space
- CE and UKCA marked
Applicable Industries: Plastics processing, food packaging, laboratory ovens, heat treatment, environmental chambers.
Model Series: ACC Series (ACC-36E, ACC-36M, ACC-66E, ACC-66M)
Installation Requirements: Panel cutout 92 × 45 mm. Minimum 10 mm clearance behind panel for ventilation.
Usage Precautions: Do not exceed terminal torque of 0.5 Nm. Ensure sensor shielding to prevent EMI in high-noise environments.
