Description
Overview
The TTH300 is provided for the highest requirements of temperature measurement with two sensor inputs. This supports sensor redundancy and sensor drift monitoring. The transmitter follows NAMUR Recommendations such as NE 89 and NE 107. As an option, an LCD indicator with operating buttons can be connected.
The TTH300 HART can be configured with ABB-tools such as Field Information Manager (FIM), with DAT200 (Asset Vision Basic) via DTM, with a Handheld via EDD, or with any standard tool using FDI-/FDT-Technology.
Transmitter with PROFIBUS PA can be configured via GSD file, EDD or DTM, with FOUNDATION Fieldbus via EDD/CF.
It is mainly generated by mutual electromagnetic radiation between components and circuits in the system, such as logic circuit
TTH300
Mutual radiation and its impact on analog circuits, the interaction between analog and logic, and the mutual mismatch between components. These are all the contents of the electromagnetic compatibility design of the PLC manufacturer for the internal system, which is relatively complex and cannot be changed as an application department. It is not necessary to consider too much, but it is necessary to select a system with more application achievements or tested.

How can we better and more simply solve the interference of PLC system?
TTH300
The selection of equipment with good isolation performance, the selection of excellent power supply, and the more reasonable routing of power line and signal line can also solve the interference, but it is relatively cumbersome, difficult to operate and costly.
TTH300
Use signal isolator to solve the interference problem. As long as this product is added between the input end and the output end where there is interference, the interference problem can be effectively solved.
Why choose signal isolator to solve the interference of PLC system?
TTH300
It is simple, convenient, reliable and low cost.
It can greatly reduce the workload of designers and system debugging personnel. Even if the complex system is in the hands of ordinary designers, it will become very reliable.

How does the signal isolator work?
Firstly, the signal received by PLC is modulated and transformed by semiconductor device, and then
The optical or magnetic sensors are isolated and converted, and then demodulated and converted back to the original signal or different signals before isolation, and the power supply of the isolated signal is isolated. Ensure the absolute independence of the transformed signal, power supply and ground.
