GE’s Enhanced Input/Output Device Packs Industry-Leading Features into Smallest Footprint Available Today

The RSTi-EP device features I/O slices that are just 11.5 millimeters wide
  • Combination of Reduced Size, Improved Performance and Diagnostic Capabilities Makes New RSTi-EP I/O Device Compatible with Industrial Internet-Enabled Applications
  • Device’s Hot-Swappable Design and Single Row of Connections Simplify Installation and Maintenance

DALLAS — November 12, 2015 — GE’s Automation & Controls solutions (NYSE: GE) today launched its new, enhanced RSTi-EP input/output (I/O) device, providing a new combination of performance and maintainability in a minimal footprint. The modular, flexible, high-density solution offers industry-leading I/O connectivity and usability in a footprint smaller than any other I/O device available today.

The RSTi-EP device features I/O slices that are just 11.5 millimeters wide, the narrowest available in the industry today, enabling it to fit into the most compact layouts while remaining easy to access and use. The device features improved performance and response time with its high-speed system bus reading up to 256 discrete I/O points in 20 microseconds. It also features an increased capacity of up to 1024 I/O points per drop.

In addition, the modular RSTi-EP unit provides performance and diagnostics capabilities akin to GE’s popular VersaMax Modular product line. The RSTi-EP I/O device allows a connected controller to know and affect the current state of the process or application being controlled by providing a networked interface for control systems to connect to the real world via sensors and actuators. With it, failures in systems can be identified at the control center as opposed to the operator having to go out to the factory floor for problem diagnosis. Its built-in Web server enables the operator to look at diagnostic faults, test I/O points and upgrade firmware over the Web. This simplifies start up, streamlines maintenance processes and increases uptime.

LEDs on the module and on each channel enable operators to quickly see where and when an error in the system has occurred, helping them to easily determine statuses and diagnoses. These LEDs also help to show clearly when the problem or error has been resolved.

Combining this diagnostics functionality with the unit’s reduced footprint creates a device that is easily usable for Industrial Internet-enabled applications and for applications where I/O can be difficult to reach — for example, in a wind turbine, where I/O can be located hundreds of feet off the ground.

“Sending someone to diagnose a problem in an application like a wind turbine can be dangerous, expensive and time consuming,” said Vibhoosh Gupta, product management leader, GE’s Automation & Controls solutions. “With our modular RSTi-EP I/O’s advanced diagnostics, operators can detect when there is an issue remotely and in real time, eliminating the need to send someone up the tower to check. Because of this, operators can quickly and cost-effectively determine if a problem needs to be fixed immediately or if it can wait until the next scheduled maintenance takes place.”

GE’s RSTi-EP I/O device has been designed for easy installation and maintenance. Its featured single-row connection level facilitates faster wiring, installation and service and its hot-swappable design enables operators to replace failed electronic components quickly and conveniently while the system continues to operate. The RSTi-EP I/O device also features an extended operating temperature range and high channel density to simplify machine design and maintenance.

The unit utilizes separate power supplies for inputs and outputs, reducing the number of power-feed modules needed while also saving space. With this design and due to the independence of the inputs and outputs, specific sections can be activated or deactivated without affecting production.

The new RSTi-EP I/O device can be used as part of stand-alone or networked unit controls, for control applications that require a higher performance capability and for those that operate in stringent environmental conditions. Examples include process and discrete manufacturing operations — both OEM and end users — such as skid-mounted equipment control, basic machine safety systems, pump and compressor control, conveyance and material handling systems.
