The MTL4544 is a repeater power supply from MTL Instruments. It is used to power and isolate 4-20 mA current loops in hazardous areas. The MTL4544 can power two transmitters in a hazardous area and repeat the current signal to two safe-area loads. This allows you to isolate your control system from the hazardous area, which can help to improve safety and reliability.
The MTL4544 has a number of features that make it a good choice for use in hazardous areas, including:
- Intrinsically safe: The MTL4544 is certified to be intrinsically safe, which means that it will not create a spark or other ignition source that could cause an explosion.
- Galvanic isolation: The MTL4544 provides galvanic isolation between the hazardous area and the safe area. This helps to prevent ground faults from propagating from one area to the other.
- Wide range of input and output voltages: The MTL4544 can accept a wide range of input voltages, from 12 V to 35 V DC. It can also output a wide range of voltages, from 9 V to 30 V DC.
- Compact size: The MTL4544 is a compact unit that can be easily mounted on a DIN rail.
