The MTLx573 converts a low-level dc signal from a temperature sensor mounted in a hazardous area into a 4/20mA current for driving a safe-area load. Software selectable features include linearisation, ranging, monitoring, testing and tagging for all thermocouple types and 2-, 3- or 4-wire RTDs. (For thermocouple applications the HAZ-CJC plug on Terminals 1-3 includes an integral CJC sensor). Configuration is carried out using a personal computer. Compact modular design with DIN rail mounting High packing density Single and multi-channel I/O modules 3-port isolation with low power dissipation Compatible with MTL5000

5500 Series IS Interface Units The MTL5500 series is the latest generation of MTL isolators. Incorporating advanced circuit design and innovative isolating transformer construction. The compact 16mm wide design reduces weight and gives a high packing density and reduction in power consumption. They build on the success of the MTL5000 series to bring the benefits of galvanic isolation with exceptional design and reliability.,II (I) GD (Ex ia) IIC,IECEx, ATEX (Baseefa) FM, CSA 3-Port Isolation High Packing density Low power dissipation Multi-channel I/O modules Compatible with preceding MTL5000 series Assessed for Functional safety IEC61508 applications Required EX numbers and information displayed on cover where applicable

MTL5561 - Fire and Smoke Detector Interface The MTL5561 is a loop-powered 2–channel interface for use with conventional fire and smoke detectors located in hazardous areas. In operation, the triggering of a detector causes a corresponding change in the safe–area current. Two channel Reverse input polarity protection "No-fail" earth fault protection
