8 Nm Damper Actuators – RA8 series

Description

VCP non-spring return damper actuators are suitable for various applications, including motorized control of dampers in ventilation systems such as Building Automation Systems (BAS), Building Management Systems (BMS), or Heating, Ventilation, and Air Conditioning (HVAC) environments.

Solutions for VCP non-spring return damper actuators are ideal for controlling dampers, air handlers, economizer units, VAV terminal units, fan coil units, fan shutters, and unit ventilators.

VCP non-spring return damper actuators are direct-mounted on standard damper shafts to control dampers.

The RA8-series non-spring return damper actuators, with torque of 8 Nm, are used to regulate dampers up to approximately 2.0 m².

The 8 Nm non-spring return damper actuators (RA8 24D and RA8 220D) offer control signals in on/off (two-position) or 3-point (3-point floating/tri-state) configurations.

The 8 Nm non-spring return damper actuator RA8 24VC features selectable control signals: 0-10 Vdc or 4-20 mA.

Auxiliary switches are equipped on digital models (on/off or 3-point), including RA8 24D S2 and RA8 220D S2, and on analog models (0-10 Vdc or 4-20 mA) such as RA8 24VC S2.

A feedback signal is standard on all RA8-series models with analog control signals.

The RA8-series actuators feature a position indicator, manual override via push button, and a direction of rotation changeable via a switch on the PCB.

The running time for all RA8-series non-spring return damper actuators is 30 seconds.
