Find all parts for your ventilation system at iacs, the Free Delivery and 1-2 Delivery is available for all the Belimo Actuators in stock

The Belimo GRC24G-SZ-T-5 is a type of Actuator used in HVAC and ventilation systems.

This kind of Actuator rotates the damper in order to control it.

The force applied by the Torque of the GRC24G-SZ-T-5 is 40 Nm.

This Rotary Actuator needs to be supported by a power supply of 24Vac/Vdc.

If you have questions concerning size or installation, refer to the Belimo custom datasheet above or email iacs for individualised support.

GRC24G-SZ-T-5 - Rotary actuator 40 Nm AC / DC 24 V, modulating

•    Running time motor 35 s / 90°, actuator adjustable
•    Operating range DC 0.5...10 V
•    Position feedback DC 0.5...10 V
•    IP 66, Manual override temporary, permanent
•    Connection with terminals

Features

• Mode of operation The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and travels to the position defined by the control signal. Measuring voltage U serves for the electrical display of the damper or ball position 0 ... 100% and as slave control signal for other actuators.


• Fields of application The actuator is particularly suitable for utilisation in outdoor applications and is protected against the following weather conditions:
  – UV radiation
  – rain / snow
  – dirt / dust
  – humidity
  – Changing atmosphere / frequent and severe temperature fluctuations (recommendation: use the actuator with integrated factory-installed heating which can be ordered separately to prevent internal condensation (see «Accessories»).


• Simple direct mounting Simple direct mounting on butterfly valves or R6..W..-S8 with ISO 5211-F05 mounting flange. The mounting position in relation to the fitting can be selected in 90° steps.


• Manual override Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked). The cover must
  be removed for this purpose.


• High operational reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.


• Home position When the supply voltage is switched on for the first time, i.e. at commissioning or after pressing the "gear disengagement" switch, the actuator moves to the home position.
  Factory default: Y2 (clockwise rotation)
