J+J - Model J4C Series -Electric Valve Actuators
At the top is without a doubt the J4C series, which offers many possibilities with its fully digital electronics. The drive can be tailored exactly to your needs. The built-in RBG status LED always indicates the current operating status via different colors and flashing cycles.
In addition to the two potential-free limit switches and the freely adjustable cam system, this series is equipped with a thermostat-controlled control room heating, a torque protection circuit and a practical RGB LED.
There are many options available for this purpose:
- Emergency function via BSR battery pack (NC/NO)
- DPS positioner with non-contact Hall sensor for analog signals (V/mA). With input and output signal or output signal only
- 3 positions with center position for 3-way valves (standard 0°-90°-180°)
- various wiring variants
A brushless motor is characterized by the fact that the moving rotor and the stationary stator are not electrically connected. This eliminates the need for sliding contacts (motor brushes), which would be subject to wear due to mechanical abrasion and brush fire.
All drives of the J4C series are equipped with a wide-range power supply for common supply voltages, which self-adaptively detects the connected voltage.
- Voltage range: J4C “S”: 24-240VAC / 24-135VDC
- Alternative: J4C “B”: 12V AC/DC J4C “H”: 230V DC
