Bray Commercial 70A180-22920536 Servo NXT Kit

The Bray Commercial 70A180-22920536 Servo NXT Kit is a high-performance modulating control solution engineered specifically for Bray Series 70 Electric Actuators, supporting sizes 70-1300 through 70-1800. Operating on 120VAC power, this "Size 18K" kit integrates advanced microprocessor-based technology to provide precise 1/4-turn valve or damper positioning. The Servo NXT modulating controller utilizes Single Finger Technology (SFT) for simplified, pushbutton programming and features auto-calibration to streamline field setup. With optical isolation for all I/O signals and stall detection to prevent mechanical damage, this kit is an essential component for critical building automation systems and industrial flow control. It natively supports various control signals, including 4-20mA and 0-10VDC, ensuring seamless integration with modern PLC and HVAC controllers.

Key Benefits

• Precision Control: High-resolution modulating capabilities for butterfly and ball valve applications.
• Universal Input Compatibility: Supports 4-20mA, 0-10VDC, 0-5VDC, and 2-10VDC control and feedback signals.
• Field Reliability: Built-in stall detection protects the internal gear train and motor from damage during blockages.
• Safety Features: Includes an onboard signal generator and fault code display for rapid troubleshooting.
• Simplified Maintenance: Calibrate the actuator at the touch of a button with auto-calibration logic.

Common Questions

Is this kit compatible with 24V actuators?
No, this specific kit (70A180-22920536) is designed for 120VAC systems. For 24VAC or 24VDC configurations, a different Servo NXT board revision is required to ensure voltage compatibility with the actuator motor.

How do I resolve a command signal fault?
Verify that the input signal type (e.g., 4-20mA) matches the electronic settings programmed into the Servo NXT via the pushbutton menu. Ensure shielded wiring is used to mitigate EMI noise, which can interfere with signal integrity.

Can I use this for manual override?
The Servo NXT kit is compatible with the standard Bray S70 declutchable handwheel. Note that engaging the handwheel will trigger a fault state on the board to prevent electrical operation while in manual mode.
