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. Line fault detection (LFD) facilities are provided across 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. System backplanes are located in safe areas and, 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. The easy migration from MTL4000 supports existing 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. The MTL4500 Series of isolating interface units introduces 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. Input and output modules handle normal process 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. Key module design features include a multiway connector 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. ♦♦ System backplanes with bussed power and safe-area connections ♦♦ Custom-designed backplanes for closest integration into process- connected systems ♦♦ Compatible with MTL4000 Series interface family ♦♦ Compact modular design with ‘plug-in’ connections ♦♦ Quick install and release mechanism ♦♦ High module/channel packing densities EUROPE (EMEA) Tel: +44 (0)1582 723633 Fax: +44 (0)1582 422283 AMERICAS Tel: +1 603 926 0090 Fax: +1 603 926 1899 ASIA PACIFIC Tel: +65 6 487 7887 Fax: +65 6 487 7997 E-mail: enquiry@mtl-inst.com Web site: www.mtl-inst.com Feb 2007 Product specifications are subject to change without notice MTL4500 I/O MODULE LIST DIGITAL INPUT Part Number Functions MTL4510 4ch DI solid-state output MTL4510B 4ch DI multifunction solid-state output MTL4511 1ch DI relay output MTL4513 2ch DI solid-state output MTL4514 1ch DI relay output + LFD alarm MTL4516 2ch DI relay output MTL4516C 2ch DI with changeover relay output MTL4517 2ch DI relay output + LFD alarm DIGITAL OUTPUT Part Number Functions MTL4521 Loop powered solenoid driver MTL4523 Solenoid driver with LFD MTL4523R Solenoid driver with LFD MTL4523L Loop powered solenoid driver + LFD MTL4524 Switch operated solenoid driver MTL4524S Switch operated solenoid driver, 24V override MTL4525 Switch operated solenoid driver low power ANALOGUE INPUT Part Number Functions MTL4541 1ch 2/3 wire Transmitter repeater MTL4541B 1ch 2/3 wire Transmitter repeater, 2 port isolation MTL4541P 1ch 2/3 wire Transmitter repeater, high power MTL4544 2ch 2/3 wire Transmitter repeater MTL4544B 2ch 2/3 wire Transmitter repeater, 2 port isolation ANALOGUE OUTPUT Part Number Functions MTL4546 1ch 4-20mA smart isolating driver + LFD MTL4546C 1ch 4-20mA smart isolating driver + oc LFD MTL4549 2ch 4-20mA smart isolating driver + LFD MTL4549C 2ch 4-20mA smart isolating driver + oc LFD � � TEMPERATURE INPUT Part Number Functions MTL4575 Temperature converter GENERAL Part Number Functions MTL4599 Dummy isolator MTL4599N General purpose feed-through module EUROPE (EMEA) Tel: +44 (0)1582 723633 Fax: +44 (0)1582 422283 AMERICAS Tel: +1 603 926 0090 Fax: +1 603 926 1899 ASIA PACIFIC Tel: +65 6 487 7887 Fax: +65 6 487 7997 E-mail: enquiry@mtl-inst.com Web site: www.mtl-inst.com Feb 2007 Product specifications are subject to change without notice EPS4510-1 MTL4510 SWITCH/ PROXIMITY DETECTOR INTERFACE four-channel, digital input Hazardous area Safe area � � � � � � � � � � � � � � � ���� �� �� ��� ��� � ������� ���� ���� � � � � ���� ���� � �� ��� � �� ��� � �� ������� � � � The MTL4510 enables four solid-state outputs in the safe area to be controlled by up to four switches or proximity detectors located in a hazardous area.
