MTL offers 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 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.
MTL4510 – MTL5510 SWITCH/ PROXIMITY DETECTOR INTERFACE 4-channel, digital input
The MTLx510 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. 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.
