MVC Series
MVCS
The Mighty Controller is a rugged next generation edge computing device targeted at device OEMs and system integrators who want to modernize their approach to local system controls. Offering vast connectivity through multiple industry standard communication protocols and flexible iGPIO, the Mighty Controller can take the place of entire control cabinets in a fractional footprint. This allows system integrators to migrate solutions from a traditional hand-wired PLC cabinet to an embedded instrument, yielding better quality, performance, efficiency, and marketability. Innovative Technology A-T Controls' proprietary iGPIO technology is the pinnacle of industrial I/O flexibility. iGPIO allows developers to programmatically assign any industrial signal type to each of the Mighty Controller's 24 physical terminal points. Each terminal point supports 0-5V, 0-10V, 0-20mA, 4-20A, and 24V digital input and output signal types. Signal types are entirely software configurable, and no external resistors or alternate wiring is required.

Other Positioners - Series 760
760OP
A cost effective, universal approach to your valve control. The modular concept (Model 760P) allows all models to be built on the base pneumatic unit. The electro-pneumatic model (Model 760E) is created by adapting an I/P Transducer to the base pneumatic unit, and a wide range of accessories easily installs inside the unit. Universal design and choice of interchangeable NAMUR IEC 534-6 rectilinear or VDI/VDE 3845 rotary mountings provide wide application flexibility Double-acting or single-acting service and split ranging afford application versatility in a single unit NACE MR-01-75-compliant material ensures operation in harsh industrial environments Non-interaction of the zero and span adjustments and positive cam locking mechanism significantly reduce the calibration and setup Modular design reduces inventory because it allows interchangeable spare parts Comes standard with 3 cams, linear, quick opening and equal % for application versatility The 760 base pneumatic unit provides cam characterization, split ranging, direct or reverse action, and single or double acting without requiring additional parts. Key design features include non-interaction of the zero and span adjustments. Series 760 valve positioners include provisions for internal limit switch mounting and position feedback devices without requiring additional housings. Thus, the need to stack housings that impede access to the main enclosure are eliminated. A spool valve is used to load the actuator for positioning in response to an input signal. A characterized cam provides mechanical feedback. There are linear, equal percentage and quick opening operation cam profiles, and a blank profile cam is available for custom applications. Rectilinear action length can range from 1/2 to 6. The feedback shaft and characterized cam can be replaced in the field to configure the positioner for use with either a rectilinear or rotary actuator. No additional parts are necessary to change between single or double acting actuators or direct or reverse action.

Air Volume Boosters
AVB
The AVB Series is an air volume booster that is mounted between the positioner and actuator. It provides the actuator with a high air flow output, whose pressure corresponds exactly to the signal pressure. Delivers high air volume to actuator Provides ample air volume flow between positioner and actuator to eliminate over and/or under travel of the control signal Provides a tight shut off to reduce a costly air consumption Exhaust filters are installed for prevention of contamination by foreign substances from outside

Block and Bleed Valve
BBV
The Block and Bleed Valve (BBV) is a NAMUR mounted module for the actuator. The BBV is used as a bypass valve for use with a manual override to shut off supply air and vent actuator ports. The BBV may also be used as a lockout valve which when properly implemented, will satisfy OSHA Standard 1910.147, “The Control of Hazardous Energy.”

Declutchable Gear Override
DeclutchableGO
The Declutchable Gear Override “Sandwich Mounts” between a pneumatic quarter-turn actuator and a ball, butterfly, plug or damper valve. This rugged device allows for manual operation during installation, system testing and in the event of an air supply failure. The DGO Series mounts directly to many of the most popular rack and pinion style actuators on the market, and does not require a bracket between the pneumatic actuator and declutchable override.
