MTL5081 Description

Short technical summary and product information.

The Measurement Technology MTL5081 is a single-channel millivolt isolator that takes a low-level DC signal from a voltage source in a hazardous area and isolates it for transmission to a receiving instrument in a safe area. It is intended for use with thermocouples and features external cold junction compensation. The module supports an input and output signal range of 0 to ±50mV, with an overrange capability up to ±55mV. It offers a nominal output resistance of 60 Ω and a transfer accuracy of linearity and repeatability less than 0.05% of reading or ±5µV, whichever is greater.

Designed for hazardous environments, the MTL5081 can be located in Zone 0, IIC, T4–T6 hazardous areas or Div 1, Group A hazardous locations. It features a response time that settles to within 10% of its final value typically within 150µs and has a frequency response from DC to 4kHz. The isolator provides 250V ac isolation between safe circuits, hazardous circuits, and power supply circuits. Switches on the module allow for enabling or disabling the safety drive in the event of thermocouple burnout or cable breakage, and for selecting upscale or downscale drive. A green LED indicates power status. The power requirement is 20 to 35V dc with a maximum current draw of 20mA.
