The module is equipped with an integrated backplane bus, power supply bus and signal wiring circuits. All electrical contacts are strengthened, with stable conductive performance and reliable contact. The overall system does not require separate external power supply, relying on the overall power supply architecture to achieve power distribution. The external wiring terminals are standardized, making wiring and subsequent rectification operations convenient, and it has 100% compatibility with all types of functional modules of the 3300 series.

Function and Positioning

This module is positioned as an integrated base for system carrying, power supply distribution and signal interaction. Physically, it provides fixed installation positions and guiding limits for power module, vibration monitoring module, shaft displacement module, speed module, relay output module, etc., ensuring the regular layout and firm assembly of all modules. Electrically, it completes centralized power supply distribution through the built-in backplane bus, evenly delivering the power output of the power module to each functional module, and building an internal signal interaction channel to achieve data and alarm signal communication between monitoring modules and output modules. External standardized wiring points are reserved to realize the introduction of the system's total signal, external connection lines, and facilitate connection with on-site industrial control systems, power supply circuits, and external alarm devices. The module has a self-checking characteristic for circuit conduction, which can assist maintenance personnel in troubleshooting issues such as poor module contact and bus breakage. It is mainly used for the hardware setup of the entire TSI monitoring system, power supply distribution, internal signal transmission, and external line connection, providing physical support and electrical link guarantee for the stable operation of the entire monitoring system.

Core Performance Parameters

The module has high mechanical structure accuracy and good slot guiding performance, supporting repeated insertion and removal of modules, with no loosening or deformation of contact points after long-term insertion and removal. The built-in bus and signal backplane have excellent conductivity, with low circuit impedance, low power transmission loss, and stable signal transmission without attenuation. The overall anti-vibration performance meets the standard, capable of withstanding continuous vibrations in the industrial cabinet operating environment, without causing contact problems. It has excellent electromagnetic shielding capabilities, with isolated protection treatment for the backplane lines, capable of resisting electromagnetic interference from frequency converters and high-voltage equipment, avoiding mutual interference of power supply and signals. It supports 7×24-hour continuous operation, with no oxidation or performance degradation of the backplane circuit and metal contacts during long-term operation, and the service life meets the requirements of industrial equipment long-term service. The electrical insulation performance is good, with reliable isolation between different circuits and to ground, effectively avoiding electrical hazards such as leakage and short circuits. The working temperature and humidity range covers the conventional industrial indoor and cabinet environments, with strong adaptability to high and low temperatures, and can operate stably under standard conditions for a long time.

General Adaptable Accessories

The supporting accessories include module fixing screws, cabinet installation brackets, bus shielding cables, external wiring terminals, line fixing clips, etc., which can complete equipment installation, wiring and line fixation work. The system end can be matched with 3300 series power modules, various vibration monitoring modules, shaft displacement monitoring modules, speed monitoring modules, relay output modules, communication modules, etc., of all functional units, and flexibly configure slots according to the number of monitoring points and functional requirements. The external can be connected to industrial power cables, shielded signal cables, industrial control system connection lines, alarm circuit control lines, etc. The internal contacts and universal connectors of the module all adopt the unified specifications of the 3300 series, making spare parts replacement and local component substitution convenient. Daily inspections, installation and disassembly, and line maintenance can be completed using conventional industrial electrical tools, without the need for specialized and complex equipment.
