ECT-EMM

The Ectron ECT-EMM is an embedded computer that can be direct attached to machinery to provide high speed analytics and in applications like rotating machinery precision frequency monitor that provides high-speed control and protection for a variety of mechanical devices. The ECT-EMM is certified to operate in conditions of -20 C to 85 C and also provide the ability to drive solenoids or relays to turn things on and off, it also provides both HART connectivity on the 4 to 20mA lines as well as EthernetIP connectivity.

Description

The Ectron ECT-EMM is an embedded computer that can be direct attached to machinery to provide high speed analytics and in applications like rotating machinery precision frequency monitor that provides high-speed control and protection for a variety of mechanical devices. The ECT-EMM is certified to operate in conditions of -20 C to 85 C and also provide the ability to drive solenoids or relays to turn things on and off, it also provides both HART connectivity on the 4 to 20mA lines as well as EthernetIP connectivity.

Applications of the ECT-EMM include

• Monitoring gas turbine engines as an OSM (Overspeed Monitor)
• Monitoring reciprocating engines and other mechanical systems as well
• An Embedded computer/Control that direct attaches to machinery in harsh environments
In the use of the ECT-EMM for Turbines, Rotating Machinery and Reciprocating Engines, input frequency signals are normally from magnetic or optical sensors that detect the movement of the machine’s operation which usually is the speed of rotation of an engine. The millisecond response of the ECT-EMM is mandatory for many rotating devices such as gas turbines.

The ECT-EMM is a highly reliable, ruggedized industrial computer. All internal systems incorporate high-reliability components:

• Internal semiconductor devices are rated from -55°C to +125°C.
• Fail-safe circuitry is incorporated such that if there is component failure, that failure must almost always result in a fail-safe condition.
• The mean time before a non-fail-safe condition exceeds 5,500,000 hours at 85°C.

ECT-EMM Certifications include

• CE and NEC
• CSA Class 1, Div 2 Groups A, B, C, and D
• ATEX Cat 3, Zone 2 hazardous area.

Several safety checks are incorporated in the ECT-EMM, some of these safety checks include:

• Checks of set point memory, processor RAM, and processor program memory are performed at startup and continually during operation
• The processor’s clocks are monitored while in operation and compared with reference to a secondary oscillator
• A hardware watchdog continuously monitors firmware operation.
• When configured as an OSM (Over Speed Monitor) Speed at last overspeed event, and highest speed since last overspeed event are stored in non-volatile memory for forensic analysis of overspeed events
• As an OSM the input Signal The acceptable frequency range is from 150 Hz to 25,000 Hz. algorithm such that the monitored result is still able to accurately determine the engine’s rpm.

Output 4 mA to 20 mA Signal This signal from the ECT-EMM is both highly accurate (0.1%) and fast responding so it can serve as an on-line check of the control system of an engine. For grounding considerations, note that the output common of the 4-20 mA signal is connected to input power common. A separate common lead should be used for the 4-20 mA signal so that power current fluctuation will not mix with the signal current.

FEATURES

• Fast response, 4 ms typical
• Outputs include 3 relays plus 4-20 mA
• HART and EthernetIP connectivity
• Rugged package to endure high vibration and shock
• Sophisticated algorithm determines shut-down
• Programmable via RS-232
• Failsafe reliability of 5,500,000 hours at 85°C
• 3 Programmable relays to turn solenoids on or off

Ectron can custom configure the ECT-EMM for your application as an OSM, Engine/Machine Monitor, Embedded computer for any application where a rugged, reliable solution is required
