HONEYWELL C7068A1007

Description

Functional Features:

• Floating-point control for proportional positioning (0–100% open)
• Manual override: Local handwheel with automatic/manual switchover
• End-stop limit switches: Built-in SPDT switches for full open/closed indication
• Feedback signal: 2–10 VDC proportional position feedback (optional on some variants)

Performance Parameters:

• Linearity: ±2% of full stroke
• Deadband: <1% of signal range
• Insulation resistance: >100 MΩ at 500 VDC
• IP Rating: IP54 (housing)

Material Composition: Die-cast aluminum housing, stainless steel shaft, nylon gear train, EPDM seals

Structural Features: Cylindrical actuator body with DIN rail or direct mount bracket; 3-wire control cable (common, signal, feedback); quarter-turn output shaft

Working Principle: The control signal (2–10 VDC) drives an internal reversible motor. The motor turns a gear train connected to the output shaft. Limit switches at 0% and 100% positions cut power when fully open or closed. The floating-point design allows the actuator to stop at any intermediate position proportional to the input signal.

Advantages:

• High torque for large dampers (up to 15 sq ft face area)
• Proportional control enables modulating HVAC operation
• Robust construction for outdoor and harsh environments

Applicable Industries: Commercial HVAC, building automation, industrial process control, cleanrooms

Installation Requirements:

• Mount actuator perpendicular to damper shaft
• Use 18 AWG shielded cable for control signals
• Set control signal range (2–10 V or 0–10 V) via internal DIP switch before commissioning

Usage Notes:

• Do not exceed 24 VAC/VDC supply voltage
• Verify end-stop switch wiring matches BMS input requirements
• Lubricate gear train annually in dusty environments
