MTL is a world leader in products designed for use in hazardous areas where there is a probability of explosiveatmospheres.
MTL's products ranges from industry renowned (IS) barriers and isolators through to sophisticated process control products, all designed for the harsh environments often encountered in the process industry.
As part of our 'Customer Committment' process, we regularly produce educational reference material to assist users in understanding the latest EU regulations and directives.
We offer the best choice in DIN-rail and backplane mounting isolators to meet the requirements of modern systems. The DIN-rail mounting isolator ranges provide a wide choice of functions with high accuracy and reliability, while the backplane mounting products are established as the leading IS system interface with solutions for all the major DCS companies.
The MTL4500 range is the latest generation of backplane mounting products, building upon the heritage of MTL4000 and introducing many key application benefits.
The MTL5500 range launches a new industry standard for DIN rail mounting products, ideally suited to a wide variety of interface tasks for process instrumentation.
The MTL5500 range modules are versatile yet simple to apply; use the latest technology and yet are well proven.
These contrasting attributes stem from the progression of our expertise in the design and manufacture of isolators for intrinsic safety and the application of innovative technology to achieve the required separation and segregation of the circuits.
The MTL5500 (DIN-rail mounting) and MTL4500 (backplane mounting) isolators share a common design, differing only in the mechanical mounting and connection methods.
MTL4573 safe barrier product specification as below
MTL4573 – MTL5573 TEMPERATURE CONVERTER THC or RTD input
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 safearea 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.
