Yokogawa to establish open process automation test bed


Y


okogawa Electric Corporation has been selected by ExxonMobil to be the Open Process Automation


(OPA) system integrator responsible for establishing the company’s OPA Test Bed. Development work and experiments conducted on the Test Bed will support ExxonMobil’s effort to move towards a standards-based, open, secure and interoperable process control architecture. ExxonMobil will use the Test Bed to evaluate candidate components and standards and provide the basis for moving OPA technology into initial industrial field trials. Yokogawa’s development office for the Test Bed will be located near ExxonMobil’s Houston Campus in Spring, Texas, and the initial stage is planned to be operational in Q4 2019.


ExxonMobil and Yokogawa are members of The Open Group Open Process Automation Forum (OPAF), an international forum of end users, system integrators, suppliers, academia, and standards organisations who are working together to develop the specifications for utilising OPA technology in next generation process control systems. An OPA-based control system is designed to support integration of best-in-class components and provide both configuration and application portability across components from different suppliers. The ExxonMobil OPA Test Bed will leverage the existing OPA development work and technological expertise of Yokogawa’s US Technology Centre. To house the Test Bed and facilitate the


objectives of this collaborative project, Yokogawa will open an office near Spring, Texas. ExxonMobil intends to share the results of systems tests using the Test Bed with their collaboration partners and OPAF. ExxonMobil will also encourage their collaboration partners to utilise the Test Bed to evaluate additional components that will be used in their independent field trials. “We are looking forward to working


with Yokogawa to stand up and operate the Test Bed for ExxonMobil and our collaboration partners,” says Brad Houk, project manager for ExxonMobil Research and Engineering Company. “This is an important milestone in the use of OPAF’s standards to create an industrial control system.

TT Electronics’ new surface mount inductors meet complex requirements of today’s high power density applications


Ferrite-based, magnetically shielded HM66M and HM78M SMD inductors feature wider temperature range and smaller footprint; ideal for industrial and telecom markets

T Electronics, a provider of engineered electronics for performance critical


applications, has launched two new surface mount device (SMD) power inductors: the HM66M series for use in high frequency power conversion systems and EMI filter applications, and the HM78M series for use in high density and high frequency DC/DC converter applications. The TT Electronics HM66M series power inductors are designed for the complex industrial and telecommunications markets. The HM66M is a shielded, miniature low-profile SMD inductor that integrates a ferrite material core for significant permeability and temperature advantages. Characterised by low losses at high frequencies, these inductors are ideally suited for power supplies and frequency converters that operate with fast switching power semiconductors on a GaN basis. Power inductance is optimised within a frequency range from 700 kHz to 4 MHz, and designed for systems that require switching frequencies up to 4MHz and operating temperatures at 125°C. The HM66M series is offered in three standard case sizes: 60, 70 and 84. The TT Electronics HM78M series power inductors are shielded, ferrite-based SMD inductors designed for use in high frequency DC/DC converter configuration popular in

demonstrated understanding of the technical requirements to create an OPA system from heterogeneous components and the ability to function as an agnostic broker of components from all suppliers.” Tsuyoshi Abe, a Yokogawa senior vice


president and head of the company's marketing Headquarters, comments, “Yokogawa is proactively participating in open architecture initiatives such as Open Process Automation with industry players globally. We are honoured to be selected for this key project, and are looking forward to working with ExxonMobil, its collaboration partners and the industry at the Test Bed facility to accelerate creation of an OPA ecosystem.”

industrial markets. With their high inductance and current values, these power inductors offer a switching frequency configuration range of 100 kHz to 3 MHz making them suitable as a buck converter or an EMI filter. TT Electronics’ HM78M series comes in two standard package sizes: 10 and 20. Semi-custom designs of both the HM66M and HM78M are also available to meet special requests. “TT’s new SMD inductors offer greater operating temperature ranges in a smaller package than competitive options,” says Raj Singaraju, global product line director, TT Electronics. “Designers now have a clear advantage in addressing the complex needs of high power density applications common in today’s industrial and telecom equipment markets.”

new miniature trigger switch for heavy duty control applications including industrial and domestic power tools has been introduced by Omron Electronic Components Europe. Its’ innovative design delivers exceptional dust, shock and vibration resistance within a very small overall size.


Ideal for all types of brushless DC applications including industrial equipment as well as cordless DC power and gardening tools, the new Omron C3AW is a highly durable and compact solution. Rated at 10mA, 42VDC, the C3AW achieves dust resistance to IEC IP6x through with a sealed rubber cover over the moving parts and an ultrasonic welded connection between the cover cases. It can withstand shocks of up to 3000 m/s2 and vibration of up to 200 m/s2 experiencing no more than 100µs of chattering at the maximum rated shock level.


Commenting, Andries de Bruin, senior European product marketing manager at Omron says, “Omron is leading the way with a control switch that meets the needs of the new generation of brushless DC power tools enabling small overall size, protection against demanding environments and a high power output while withstanding vibration. The C3AW is one of the smallest solutions on the market offering this level of environmental protection.” He continues, “Omron manufactures this new switch using a fully automatic assembly process, guaranteeing the highest quality of production.” With an overall size of just 25mm wide by 13.5mm deep by 28.5mm high, the C3AW is rated for at least 300,000 operations. It can be used at temperatures between -20 and +65ºC.
