Product Short Description
Product Name: Deltat ACC-72E Dual-Loop Temperature Controller
Product Introduction: The ACC-72E is a dual-channel (dual-loop) microprocessor-based temperature controller from Deltat Controls. It provides independent temperature control for two separate zones or processes from a single 1/8 DIN instrument. Ideal for applications requiring two temperature zones such as dual-zone ovens, extruders, or heat-seal systems.
Description
Technical Specifications:
- Input Channels: 2 independent inputs
- Input Type: K, J, T, E, S, R, B, N thermocouples; Pt100, Pt1000 RTDs (per channel)
- Control Output (per channel): Relay (SPDT), SSR drive, 4–20 mA
- Control Mode: On/Off, PID, Time-Proportional (per channel)
- Power Supply: 85–265 VAC / 24 VDC
- Accuracy: ±0.1% of reading + 1°C
- Resolution: 0.1°C
- Sampling Rate: 2 readings per second per channel
- Operating Temperature: 0°C to +50°C
- Dimensions: 96 × 48 × 78 mm (1/8 DIN)
Functional Features:
- Independent PID tuning per channel
- Dual alarm outputs (high/low per channel)
- Event logging on both channels
- Remote setpoint capability on both loops
Performance Parameters:
- Repeatability: ±0.2°C per channel
- Relay Rating: 16 A resistive per channel
- Isolation: 500 V between channels
Material Composition: ABS flame-retardant housing, polycarbonate front panel, phosphor bronze terminals.
Structural Features: 1/8 DIN panel-mount with dual display zones on a single screen (alternating readout).
Working Principle: Each channel independently samples its sensor, computes PID or on/off control, and drives its own output. The microprocessor manages both loops simultaneously with independent timing.
Key Advantages: Two complete controllers in one instrument; reduces panel space and wiring cost.
Applicable Industries: Dual-zone furnaces, injection molding, food processing, laboratory equipment.
Model Series: ACC Series
Installation Requirements: Same as ACC-36E — 92 × 45 mm cutout, 10 mm rear clearance.
Usage Precautions: Verify correct sensor type assignment per channel. Do not cross-wire channels.
