3300/03-01-02 Product Description

Product Introduction

3300/03-01-02 is a relay output module of the 3300 series by BENTLEY, which is an important component of the industrial rotating machinery condition monitoring and protection system. The product adopts the mature industrial relay control circuit design, featuring a compact structure, sensitive operation, stable performance, and excellent electromagnetic protection and environmental adaptability. It can operate continuously in complex industrial environments for a long time. This module mainly receives alarm signals from monitoring modules such as vibration, shaft displacement, and rotational speed, completes signal conversion and outputs switch quantity contact signals, and links the on-site alarm devices and equipment interlock system to achieve abnormal state reminder and safety protection. It effectively avoids the expansion of equipment failures, unplanned shutdowns, and safety accidents. It is the core component of the entire monitoring and protection system for realizing alarm and interlock functions. Basic Information

This product belongs to the 3300 modular monitoring system. The model clearly defines the channel configuration, contact specifications and hardware configuration parameters. The equipment adopts a standard plug-in rack structure, and its size is fully compatible with the universal rack of the 3300 series. It supports direct plug-in installation, and the operations of disassembly, debugging, maintenance and spare parts replacement are simple. The on-site wiring and connection are convenient and standardized. The entire machine is manufactured in strict accordance with industrial electrical safety and electromagnetic compatibility standards. The enclosure has the ability to resist dust and slight mechanical impact, and can operate stably in conventional working environments such as industrial cabinets, central control rooms, and on-site control rooms. The module is uniformly powered by the power module of the same series, and the electrical interface is standardized, allowing for quick connection to the system circuit. It is highly compatible with all series of monitoring modules and functional modules, and is flexible in system expansion.

Function and Positioning

This module is a dedicated alarm relay output unit that independently receives warning, danger and fault signals transmitted by various monitoring modules at the front end. The internal relay circuits are isolated from each other, and their operations do not interfere with each other. The module can convert electrical signals into passive switch contact signals. When monitoring parameters exceed the set threshold, sensor failure, circuit open circuit and other abnormal conditions occur, the relay quickly completes the on-off action, driving the external audible and visual alarm device, intermediate relay, PLC control system and unit safety interlock circuit to work, completing local alarm, remote signal upload, equipment interlock shutdown and other operations. The equipment is equipped with a self-check function for operating status, which can provide real-time feedback on its own and contact point working status. It is mainly applied in scenarios such as alarm signal transfer, on-site audible and visual indication, equipment safety interlock, and remote transmission of operating signals, to build a complete unit safety protection logic.

Core Performance Parameters

The module has precise signal recognition and can stably match the alarm output levels of the same series monitoring modules. The relay action response is fast, and the signal transmission delay is extremely low. The contact load capacity complies with the standards for industrial control circuits, and the on-off performance is reliable. The mechanical life and electrical life meet the requirements for long-term continuous use. The internal integrated filtering and electrical isolation circuits can effectively resist electromagnetic interference generated by large-power motors, frequency converters, and high-voltage lines, avoiding false triggering and false operation. The equipment supports 7×24-hour uninterrupted operation and has no significant performance degradation under long-term working conditions. The circuit insulation performance is excellent, which can effectively isolate the monitoring signal circuit from the external control circuit, improving the overall electrical safety of the system. The working temperature and humidity range is suitable for industrial indoor and cabinet environments, and the environmental tolerance is strong.

General Adaptable Accessories

During on-site construction, auxiliary materials such as control cables, shielded cables, standard terminal blocks, cable fixing clips can be matched to meet the requirements of wiring, connection and line fixation. At the system level, it is compatible with the standard racks and power modules of the 3300 series, and can be freely combined with various functional modules such as vibration monitoring modules, shaft displacement monitoring modules, and rotational speed monitoring modules. According to the alarm points and interlock logic at the site, it can be flexibly configured. The output end can be externally connected to audible and visual alarm devices, intermediate relays, industrial control equipment, unit interlock protection circuits, etc. The module interfaces, terminal blocks, and common vulnerable parts all adopt the general specifications of the 3300 series, making spare parts procurement and replacement convenient. Routine inspections, function tests, and fault troubleshooting can be completed using common industrial electrician tools.

Applicable Equipment Domains

The product is widely used in industries such as thermal power generation, petrochemicals, metallurgy, coal chemical industry, oil and gas production, and heavy equipment manufacturing, and is applied in state monitoring systems of large and medium-sized rotating mechanical equipment such as steam turbine generators, gas turbines, centrifugal compressors, large draft fans, smoke gas turbines, high-pressure large pump sets, heavy gear machinery, etc. The main equipment is mainly installed in the main control cabinet rooms of power plants, control rooms of chemical plants, power generation machine rooms of metallurgy, and electrical cabinet areas of industrial enterprises, providing alarm signal output, on-site warnings and safety interlock guarantees for the entire monitoring system, ensuring the safe, stable and continuous operation of the core units.
