800 I/O is a comprehensive, distributed and modular process I/O system.
Communication with parent controller and plc via industry standard fieldbus.
The CI840 Fieldbus Communication Interface (FCI) module is a configurable communication interface.
Can perform signal processing, collection of various monitoring information, OSP processing, running hot configuration,
HART pass-through and I/O module configuration.
The CI840 is designed for redundant applications. The FCI is connected to the controller via the PROFIBUS-DPV1 fieldbus.
Module terminal units are used, TU846 with redundant I/O and TU847 with non-redundant I/O.

Steam turbine, also known as steam turbine, is a rotating steam power plant. The high temperature and high pressure steam through the fixed nozzle becomes an accelerated airflow, which is sprayed onto the blade, so that the rotor with the blade row rotates and does external work. Steam turbine is the main equipment of modern thermal power plant, also used in metallurgical industry, chemical industry, Marine power plant.
The structure of a steam turbine consists of a rotating part and a stationary part. The rotor comprises a main shaft, an impeller, a moving blade and a coupling. The stator comprises an inlet part, a cylinder, a partition and a stator cascade, a gland and a bearing, etc. What causes the turbine spindle to bend? Causes of turbine mechanical and electrical spindle bending
1, the cylinder insulation is poor. If the cylinder insulation is not good, there will be a large temperature difference between the upper and lower cylinders when the steam turbine starts and stops. In general, the temperature of the upper cylinder is higher than that of the lower cylinder, which makes the upper cylinder expand higher than the lower cylinder and the upper cylinder arch. Hengxinglong Xiaobian suggested that this phenomenon is commonly known as “cat arch back”. When the arch back occurs, the amplitude gap of the lower cylinder block decreases, resulting in dynamic and static friction.
2, water or cold steam into the cylinder.
3, rotor thermal bending caused by *** bending.
4. Due to the strong vibration during operation, it causes dynamic and static friction and generates heat after friction. Due to the intense vibration friction, the temperature of the friction part is very high, resulting in a reduction in the yield strength of the material. Excessive thermal stress causes the thermal deformation of the shaft, and causes the convex bending of the axial friction side, which further intensifies the temperature rise and leads to the increase of the bending of the shaft.
5. Improper adjustment of shaft seal during installation or maintenance, insufficient clearance of gland.
This is why the turbine main shaft is bent. I hope it helps you. Hengxinglong motorized spindle – compact structure, light weight, small inertia, small vibration, low noise, fast response and many other advantages in one, with high speed, high power and many other advantages. In the field of CNC machine tools has also been more and more perfect application. We undertake all kinds of high-speed motorized spindle/spindle motor/high-speed motor design and manufacturing at home and abroad as well as all kinds of high-speed motorized spindle/spindle motor/high-speed motor/spindle head repair and maintenance abroad.
