Westlock Controls announced that its ICoT 5400 is the first smart positioner to successfully pass the ITK 6.0.1. criteria. The ICoT 5400 is a fully digital positioner that provides reliable measurement of valve stem position for a wide range of actuators, including spring and double-acting variants. Designed to meet FOUNDATION FieldbusTM protocols, the positioner fulfills the control requirements of the petrochemical, oil and gas industries and can be incorporated into customers’ plant network infrastructures.

Based on the existing ICoT 5000 series of digital positioners, the enhanced 5400 features improvements to both firmware and hardware, including a unique graphical display, an extended trunk length, single loop integrity and multi-drop capabilities for up to 32 devices per segment. Specifically designed for remote applications, ICoT smart valve positioners can be mounted up to 150 feet away from the controlled device, making them ideal for valves that are located in high vibration or extremely corrosive environments. Their unique non-contact sensor, employing an external magnetic module, enables the use for advanced controls strategies, while extremely accurate tracking of the control signal by using a rotating analog-to-digital converter that interfaces between the sensor and microprocessor.

“By extending our ICoT 5000 series to include FieldbusTM capability, we were not only able to extend our customer base, but it also enabled us to enhance the features of the existing range and develop a new generation of smart valve positioners”, comments Mike Lutolf, Global Product Manager – Controls. “With a consumption of less than 12 mA, the 5400 is not only one of the most energy-efficient positioners on the market, but also the first smart positioner to pass the ITK 6.0.1. criteria, proving its complete interoperability”.
