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.

SC58 Temperature Controller
3218
The WIKA SC58 temperature controller is developed for thermostat applications. It features simple operation and a high switch rating. The design of the WIAK SC58 temperature controller enables the controller to be used as an alternative to the purely mechanical remote reading thermometer ( WIKA TF58 ). In comparison to mechanical thermostats, the SC58 can handle significantly more switching cycles and thus has a higher operating life.

SC64 Temperature Controller
3221
The WIKA SC64 temperature controller is a temperature controller for simple thermostat applications. It features simple operation and a high switch rating. Its round case enables the instrument also to be used in applications where mechanical controllers were used so far. In addition, the WIKA SC64 can handle significantly more switching cycles.

CS4R Temperature Controller
3224
The WIKA CS4R temperature controller is a compact digital temperature controller for the display, control and monitoring of temperature. The CS4R controller features a multi-function input, meaning the configuration of the sensor input can be set. Thus the flexibility of the temperature controller is considerably increased, and warehousing is made more accessible. An alarm output for monitoring the actual value is also available as standard. The control parameters can be set across broad ranges. Auto-tuning, which facilitates finding the optimal control parameters, can be activated. The temperature controllers are intended for DIN-rail mounting. The control output can be set either as a relay (for slow control), as logic level for the control of electronic solid-state relays (for fast control and high current loads) or as a continuous 4 … 20 mA output. The versions with 4 … 20 mA control output can be reconfigured by the user and operated as a transmitter with 4 … 20 mA output signal. A heater burnout alarm for the heater current monitoring and a serial interface RS-485 are available optionally.

CS6x PID Temperature Controller
7359
The compact WIKA CS6S, CS6L and CS6H PID temperature controllers offer display, control and monitoring of temperatures. The WIKA CS6x PID temperature controllers feature a multi-function input for resistance thermometers, thermocouples and standard signals, meaning the configuration of the sensor input can be set. Thus the flexibility of the controller is considerably increased, and warehousing is made easier. An alarm output for monitoring the actual value is also available as standard. The control parameters of the PID temperature controllers can be set across broad ranges. Auto-tuning, which facilitates finding the optimal control parameters, can be activated. The monitoring output of the PID controller can be set either as a relay (for slow control), as logic level for the control of electronic solid-state relays (for fast control and high current loads) or as a continuous 4 … 20 mA output. Hysteresis is available with on/off control mode. As options, for the model CS6x PID temperature controllers there is a 2nd alarm output available for the monitoring of the actual value and the control loop, and a heater burnout alarm for monitoring the monitoring output, or, alternatively, a 2nd monitoring output. An RS-485 serial interface is also possible. In addition, for this model series various accessories, such as terminal covers or current transformers, are available. The ingress protection of the PID controller is IP66 at the front and IP00 at the back (in accordance with IEC 60529/EN 60529). The actual value of the measurement is indicated in red, the setpoint in green, each in 5 digits with a 7-segment LED display.

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.
