PRKCA-BAC-S2-T - Rotary Actuator Fail-Safe for Butterfly Valves

Overview:

The PRKCA-BAC-S2-T is a rotary actuator designed for fail-safe operation with butterfly valves. With a torque motor delivering 160 Nm of force, this actuator ensures precise and reliable control over valve operations. It operates on a nominal voltage range of AC 24-240 V or DC 24-125 V, providing flexibility in power supply options. Equipped with two integrated auxiliary switches, it offers enhanced functionality, including the conversion of sensor signals and communicative control via BACnet MS/TP, Modbus RTU, Belimo-MP-Bus, or conventional control methods.

Key Features:

  • Fail-Safe Operation: Designed for fail-safe operation, ensuring safety and reliability in critical valve applications.

  • Integrated Auxiliary Switches: Comes with two integrated SPDT auxiliary switches, allowing for additional control and feedback options.

  • Communicative Control: Supports communicative control via BACnet MS/TP, Modbus RTU, and Belimo-MP-Bus, facilitating integration into building automation systems.

  • Variable Operating Range: Offers variable operating ranges for control signals (Y), position feedback (U), and fail-safe position settings, providing flexibility in system configuration.

Technical Specifications:

  • Electrical Data: Operates on a nominal voltage range of AC 24-240 V or DC 24-125 V, with power consumption ranging from 9 W in rest position to 52 W in operation. Supports parallel operation and data bus communication.

  • Functional Data: Torque motor delivers 160 Nm of force, with an operating range of 2-10 V for control signals (Y) and position feedback (U). Offers variable settings for fail-safe positions and bridging times.

  • Safety Features: Equipped with two SPDT auxiliary switches and manual override functionality via hand crank for manual operation during emergencies.

Communication Protocols:

  • Supports communicative control via:
    • BACnet MS/TP
    • Modbus RTU
    • Belimo-MP-Bus
