Bray is the first manufacturer to incorporate Rockwell’s Add-on Profile (AOP) for an EtherNet/IP capable actuator. This AOP enables customers to seamlessly register and quickly configure Bray S70 Actuators into Rockwell PLC’s via the Studio5000 software. As a result, customers automatically see I/O data with meaningful and descriptive names.

The low profile weatherproof actuator is UL listed Type 4, 4x and IP65. Polyester powder coated die-cast aluminum cover and base, for exceptional corrosion, wear, impact and ultraviolet resistance.

Keywords: Optical Transfer Function (OTF), Incoherent image, Fourier transform, Equivalent pass-band, spatial frequency, apodisation parameter. 1. INTRODUCTION.

Prominently labeled and color coded yellow for open, red for close – the display indicates valve position through the full range of travel. The O ring sealed dome is made of high impact, heat, chemical and ultraviolet resistant clear polycarbonate and designed to withstand caustic wash down ensuring excellent corrosion protection.

Servo NXT Ethernet/IP reduces complexity during installation and commissioning of the Series 70 actuator. Connect the Series 70 Servo NXT directly by Ethernet, eliminating costly communication protocol converters and gateways. With the Add on Profile (AOP) from Rockwell, Series 70 Actuators can also be quickly configured into Rockwell PLC's via Rockwell Studio5000 software.

Bray's Series 70 NXT is the first device with built in Ethernet/IP connectivity, allowing the device to connect directly to Rockwell PLC's over Ethernet.

Standard on all models. The declutch-able manual override prevents handwheel movement during motor operation. When manual operation is desired, pull the handwheel out exposing a yellow stripe around the handwheel shaft. This indicates the handwheel is engaged and manual operation is available.

The Servo NXT control module uses assembly data to set valve position and reports operational characteristicsby transmitting data over the EtherNet/IP protocol directly to the Rockwell/Allen-Bradley PLC for visualization and fault notifications. Another benefit is the device configuration data is stored in the Logix controller, enabling Automatic Device Configuration anytime the device is replaced.

Interrupts power to the motor when handwheel operation is engaged. The manual override operates like a watch adjusting knob. To engage the manual override, simply pull the handwheel to its outermost position. A yellow stripe is revealed to visually indicate manual override engagement.

Bray's Series 70 electric actuators now offer expanded capabilities with Ethernet/IP connectivity built directly into the actuator.

Bray’s patented CAM design includes standard green (open) and red (close) CAMs which are adjustable with finger touch or screwdriver with no additional tools. Standard factory setting allows 90° travel between open and close positions.

Designed to prevent over-travel in the open or close direction during manual operation. Travel stop bolts include a locknut to prevent loosening, seals to prevent water ingress, and spacers to prevent adjustment between 0° and 90° limit switch settings. Travel stop bolts permit 5° of over travel.

On standard models, the actuator limit switches are pre-wired to an easily accessible and clearly marked terminal strip for customer wiring. The terminal strip has been placed near the two conduit entries with ample room for running wire leads. An easily accessible green plated ground screw is provided. A wiring diagram is included inside the cover for easy reference.

Series 70 Servo NXT Ethernet/IP™ control module provides feeback and diagnostics data over TCP/IP including position, status, alarms, stroke count, motor operating time, motor current, stroke times, directional changes and more, providing actionable increased diagnostics capability and predictive maintenance by detecting deterioration.

Corrects any misalignment between the valve and actuator without introducing side load to the position indicator shaft assembly.
