8 Nm damper actuators - RA8 series

damper actuators 8Nm - RA8-series

Description

VCP non-spring return damper actuators are suitable for many applications including motorised control of dampers in ventilation systems such 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 control dampers, air handlers, economizer units, VAV terminal units, fan coil units, fan shutters, and unit ventilators.

VCP non-spring return damper actuators to be direct mount on standard damper shafts to control dampers.

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

The 8 Nm non-spring return damper actuators RA8 24D and RA8 220D are with control signal on/off (two-position) or 3-point (3-point flaoting / tri-state).

The 8 Nm non-spring return damper actuators RA8 24VC is with selectable control signal 0-10 Vdc or 4-20 mA.

Auxiliary switches are equipped on the digital (on/off or 3-point) types of non-spring return damper actuators types RA8 24D S2 / RA8 220D S2 and on the analogue (0-10 Vdc or 4-20 mA) types of non-spring return damper actuator type RA8 24VC S2.

Feedback signal is standard on all the 8 Nm non-spring return damper actuators RA8-series with analogue control signal.

The 8 Nm non-spring return damper actuators RA8-series are equipped with position indicator, manual override by push button, direction of rotation changeable via switch on pcb.

Running time for all 8 Nm non-spring return damper actuators RA8-series is 30 seconds.
