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
