ABB 500MTM02 | Measurement and transmission module

ABB 500MTM02 is a measurement and transmission module in the ABB 500 series.

· Product type: It belongs to the measurement and transmission module, which may be used to convert various physical quantities (such as temperature, pressure, flow rate, etc.) 

into standard electrical signals for the purpose of acquisition, processing, and control by controllers in industrial automation systems.

· Input characteristics: It can receive various types of input signals, such as signals from temperature sensors such as thermocouples and thermal resistors, or millivolt signals 

from pressure sensors, pulse signals from flow sensors, etc. Capable of adapting to sensor inputs of different ranges and accuracies, with a wide input signal range and good 

signal linearity.

· Output characteristics: It usually outputs standard analog signals, such as 4-20mA current signals or 0-10V voltage signals, and may also support digital signal output, such 

as HART protocol, Profibus PA protocol, etc., to achieve digital communication with other devices. The output signal has high stability and accuracy, and can accurately reflect 

changes in input physical quantities.

· Performance characteristics: It has a certain measurement accuracy, which may be between ± 0.1% and ± 0.5% FS (full scale), depending on the product design and 

application scenario. Has good anti-interference ability and can work stably in complex industrial electromagnetic environments. It may also integrate some diagnostic 

functions, such as sensor fault diagnosis, communication fault diagnosis, etc., to facilitate timely detection and resolution of problems.

· Physical characteristics: Adopting a compact modular design, the size is small and easy to install in industrial control cabinets or field instrument boxes. The shell material 

may have good protective performance, such as IP65 protection level, which can prevent dust and water from entering and adapt to harsh industrial site environments.

· Working environment: The working temperature range is generally between -40 ℃ and+85 ℃, which can adapt to different industrial environment temperatures. Can work 

normally under certain humidity conditions, such as a non condensing environment with a relative humidity of 5% -95%.
