Io Hvac Controls OAD-12-MOD Outdoor Air Damper Motor 0-10 Vdc

Product Description

The IO HVAC CONTROLS OAD-12-MOD is a 12-inch outdoor air damper actuator motor designed for modulating control in commercial and residential HVAC systems. It accepts a 0-10 VDC control signal, allowing precise positioning of the damper blade to regulate outside airflow into an air handling unit or rooftop package system. This actuator is a direct-drive motor assembly intended for field installation by licensed HVAC technicians. It is suited for ventilation control applications where proportional damper positioning is required rather than simple open/close operation.

The OAD-12-MOD is applied in forced-air systems where outdoor air economizer control, ventilation rate adjustment, or mixed-air temperature management is needed. Typical installations include rooftop units, air handling units, and make-up air units in light commercial and commercial settings. The 0-10 VDC signal input makes it compatible with building automation systems and direct digital control platforms that output analog voltage signals for damper modulation.

Key Features

• 0-10 VDC modulating control signal for proportional damper positioning
• Designed for 12-inch outdoor air damper applications
• Compatible with BAS and DDC analog voltage control outputs
• Compact actuator housing suitable for field mounting on standard damper frames
• Supports economizer and ventilation rate control strategies

Compatibility

Designed as an OEM-style replacement or new-installation actuator for 12-inch outdoor air dampers in forced-air HVAC systems that use 0-10 VDC modulating control.

Installation Notes

Installation should be performed by a qualified HVAC technician familiar with low-voltage control wiring and damper actuator mounting. Disconnect and lock out power to the air handling unit before beginning any wiring or mechanical installation work. Verify the control system outputs a 0-10 VDC signal compatible with this actuator before completing wiring connections. Follow local mechanical and electrical codes, including applicable NEC requirements for low-voltage control circuits.
