Interface Function Block Monitors Engine Operation

Wago's new J1939 interface function block increases large engine efficiency by tracking, and reacting to, engine performance parameters via the Wago-I/O-System. The J1939 interface is compatible with SAE's J1939 protocol, which is favoured by engine manufacturers. This enables Wago-I/O-System programmable controllers and IPCs to cost effectively monitor and optimise engine operation on large vessels, generator sets or within plants. Monitoring multiple engines on one controller area network (CAN), the J1939 interface directs Wago-I/O-System components to run auxiliary devices such as cooling fans or to execute alarm, start/stop and speed control functions.

Engine data may also be transferred to a local human-machine interface (HMI) or to a SCADA system via fieldbus. The majority of Wago-I/O-System controllers, couplers and modules carry approvals including UL, ABS, DNV, GL, CE and ATEX. These make the J1939 interface and the Wago-I/O-System suitable for diverse engine monitoring applications, from those in oil fields to those aboard workboats and cargo vessels.

To simplify J1939 engine monitoring integration, Wago's Custom Product Division has developed a J1939 enclosure. The pre-wired NEMA 4X enclosure is equipped with Wago-I/O, such as the Ethernet 2.0 media redundancy controller for redundant networks. The J1939 interface will be displayed within Booth 6125 at the Offshore Technology Conference, which is due to be held on 2-5 May in Houston.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
