Emerson has recently released its ASCO 141 Series Advanced Redundant Control System (ARCS) to provide a redundant solution for a variety of emergency shutdown valve applications, such as those found in the chemical, power, oil and gas industries. Available globally, it includes various redundant solenoid configurations to enhance the reliability of the process and meet specific safety or reliability requirements in automation processes. The single inlet/single outlet design provides a streamlined installation process compared to traditional bypass systems, while almost eliminating potential failure points.

The ASCO 141 series ARCS is designed for use as a component in safety instrumented systems. Utilizing 1oo2, 2oo2 or 2oo3 voting solenoids to enhance the reliability of the circuit, it functions as a redundant pneumatics tripping device to control the pilot air signal to a process valve actuator. The ARCS features either two or four electrically actuated solenoid valves, visual indicators and a manually controlled bypass or isolation valve. The unique control functionality allows for maintenance of the solenoid valves without having to shut down the process valve. In fact, the use of the maintenance bypass or isolation valve is not required for functional testing of the ARCS unit — a downtime-reducing feature not possible with common bypass functions.

“By addressing the concerns common with typical bypass systems — particularly those in critical or emergency shutdown applications — our ASCO 141 series ARCS provides a reliable, time-saving alternative,” said vice president of global marketing for Emerson’s industrial automation business, Erik VanLaningham. “Although the use of a common bypass is a typical solution, the end-user doesn’t know if they’ll be able to shut down on demand in the event of an emergency because their redundant system is in bypass mode. This is where our unique ARCS value proposition comes in. The ARCS individual valve isolation option provides increased safety and operational availability during online maintenance to help customers achieve their required SIL rating.”

With just a single part number, the ASCO 141 series ARCS features several advances that simplify specification, installation and operation. Supplied as a fully integrated, comprehensive solution using a manifold instead of individual valves, ARCS comes pre-tested from the factory and ready to install. The direct valve-to-valve design eliminates pipework and fittings between the solenoid valves and minimizes leak points for increased reliability and a lower total cost of ownership. A status indicator with feedback helps facilitate preventive maintenance while providing online fault detection. It provides digital input feedback (via pressure switches or Emerson-exclusive GO Switch options) to the control room. And for additional peace of mind, the ASCO 327 series 3/2-way direct acting solenoid valves included on the ARCS manifold are certified to SIL 3 capable (exida) standards.

A direct-acting platform with advanced diagnostic capability and online maintenance features, ARCS is suitable for a wide variety of valve piloting applications to meet both safety and operational availability requirements.

MC Why Manufacturing Career Opportunities Will Soon Be Booming 1 400x275

A common misconception surrounds manufacturing today: the idea that introducing robotics and other automation equipment into the picture will rapidly dry up the industry’s career opportunities. In fact, automation does the opposite – by creating even MORE demand for human intelligence and ingenuity.

Building and maintaining the factory of the future requires capable individuals who enjoy solving problems and thrive on novelty. While the humdrum jobs of the past may be in short supply as they get transferred to robots, the installing, troubleshooting, and innovating tasks — essentially, the exciting ones — will be desperately in need of takers.

Furthermore, these jobs tend to be safer, pay better, and offer more opportunities for growth. Read on to find out how you can use your skills to thrive in today’s manufacturing job market.

 Have you ever wondered what it’s like to build the factory of the future? From fully autonomous mobile robots to human-like machine vision systems, the things that used to be “science fiction” are now real. What’s more, You can be working alongside them.

It’s obvious that opportunity will be knocking loudly at the door of anyone with a degree in engineering. But did you know that the automation industry also needs people who aren’t engineers? In fact, one of the job titles that’s poised to grow exponentially is automation technician, which you can do with just an associate degree or even a high school diploma.
