Key module design features include a multiwayconnector to the backplane for safe-area and power supply connections. Hazardous-area connections simply plug into the front of the module; this simplifies installation and maintenance and reduces time, cost, and the risk of errors. Status LEDs, configuration switches and ports are located on the top or side of individual modules for easy access. The compact, 16mm wide, design reduces weight and gives exceptionally high packing density. Input and output modules handle normalprocess applications covering on/off or analogue signals between hazardous-area equipment and safe-area systems. Modules incorporate proven intrinsically safe isolation techniques, internationally certified for protecting equipment and wiring in all zones and explosive atmospheres. Input, output and power-supply circuits are isolated from each other, giving maximum flexibility for control loop applications. The MTL4500 Series of isolating interface unitsintroduces key concepts for integrating intrinsic safety into large or medium sized process-connected systems. Being exceptionally compact, the units give high packing densities and plug into system backplanes with safe-area connections made by multiway connectors an approach which not only simplifies engineering but also reduces installation and maintenance costs. MTL4500 modules are held on the backplane with plastic clips that are simple to use, secure in operation and avoid the use of screws, giving further reduction in installation and maintenance time and cost. Product specifications are subject to change without notice > System backplanes are located The easy migration from MTL4000 > in safe areasand, because the hazardous-area circuits are connected directly to the modules, do not need to be certified. See MTL series backplanes, enclosures and accessories for full details. supportsexisting installations because MTL4500 modules can be mounted on backplanes that were designed for MTL4000. A simple modification uses the backplane mounting holes of the MTL4000 to accept the mounting clips for the MTL4500 modules. This ensures continued availability and operation of process plant with new I/O modules and enhanced functionality. Line fault detection (LFD) facilities are providedacross the range of I/O functions; on the switch/proximity detectors, the MTL4523 solenoid/alarm driver and the isolating drivers. Analogue input units such as the MTL4541 provide line fault detection by repeating o/c or s/c currents to the safe-area control system. > Based on proven IS isolation technology, MTL4500 Series modules do not need a high integrity earth and the associated circuits can be left floating or be earthed at any one point in accordance with good earthing practices. MTL4500 Series provides single channel single loop integrity across the range with the addition of dual channel options for the switch/proximity modules, analogue inputs and analogue outputs. There is even a quad channel switch/proximity input module for the maximum channel density. > EUROPE (EMEA) Tel: +44 (0)1582 723633 Fax: +44 (0)1582 422283 AMERICAS Tel: +1 603 926 0090Fax: +1 603 926 1899 ASIA PACIFIC Tel: +65 6 487 7887Fax: +65 6 487 7997 Feb 2007 E-mail: [email protected] Web site: www.mtl-inst.com size="-2">

Product specifications are subject to change without notice EPS4510-1 > Hazardous area Safe area The MTL4510 enables four solid-state outputs in the safe area to becontrolled by up to four switches or proximity detectors located in a hazardous area. Each pair of output transistors shares a common terminal and can switch +ve or ve polarity signals. A range of module configurations is available (see Table 1) through the use of selector switches. When proximity detector modes are selected, LFD is enabled and the output switches to OFF if a line fault is detected. > See also common specificationNumber...
