New generation hazardous area remote terminals

Power management company Eaton has launched a newMTL GEC- MA RT remote operating terminal, which enables plant managers to reduce operation costs, optimise productivity and increase plant safety.The new MTL GECMA RT has a unique modular design and is a next generation remote terminal which features state-of-the-art technology to offer unparalleled levels of safety, making it ideal for use in hazardous EX zone areas in chemical, pharmaceutical, refinery and oil and gas industries worldwide.The MTL GECMA RT consists of five electronic modules; the display unit, power supply, commu- nications modules, keyboard and mouse. The terminal’s modularity means upgrades to existing installations are quick and easy, which can save time, and minimise costly maintenance and downtime.

Traditionally, the whole unit would have to be dismantled off site, but now with MTL GECMA RT, individual parts can be replaced simply on site, increasing plant availability. Of vital importance, the modules are individually approved to global hazardous certification for Zone 1 environments. Eaton is leading the way in safety and the MTL GECMA RT features a couple of unique functions. First is a unique intrinsically safe cable for secure data transmission. Us- ers can specify an Ethernet or fibre optic cable between the control room and remote terminal, with no need for additional external cable protection. Secondly, the terminal features a unique visual alarm to immediately warn users in the event of a process failure. Enquiries:Tel. 011 791 6000 or email sales@extech.co.za

Soft starter for electric motors TELE has introduced the new 3 ph soft starter with true 3 ph control and integrated current control for a nominal motor power 2,2 kW up to 22 kW.Tele offers you the new MS3 soft starter for a continuous starting procedure of asynchronous 3 ph motors. The unit is thyristor based and integrates current measurement and current limiting without external components and wiring.This function controls and limits exactly the maximummotor current that is used to start the whole systemwithout overloading the motor and drive mechanics. Additional power peaks and flickers in the mains are reduced to a minimum, so the stability of the supply is much higher compared to star/delta or direct motor start- ers.The overall size of the new MS3 is compact and saves space in the cabinet.The fan-less design improves time between maintenance. The full 3 ph control paired with current control makes the MS3 the ideal device for heavy starting drives and machines. Power dissipation in start and standby mode is extremely low, due to the use of modern and state of the art control and power devices. Enquiries:Tel. 011 454 8053 or email edwin@vepac.co.za
