3300/03-01-03 Product Description

Product Introduction

3300/03-01-03 This is the output module of the BenTLY 3300 series relay, which is an important signal transfer and interlock execution unit in the rotating machinery condition monitoring system. This module adopts an industrial-grade relay circuit design, with fast response speed, strong working stability, and excellent anti-electromagnetic interference capability. It can be adapted to various complex industrial sites. Its main function is to receive the alarm instructions from various monitoring modules at the front end, convert the analog alarm signals into standard switch quantity contact signals, drive the on-site alarm devices and the unit interlock circuit to act, realize abnormal condition sound and light indication and safety interlock protection, effectively prevent the expansion of equipment failures and the occurrence of safety accidents. It is an indispensable supporting component of the entire monitoring and protection system. Basic Information

This product belongs to the 3300 modular monitoring system. The model corresponds to the dedicated channel configuration, contact specifications and hardware version. The equipment adopts a standard plug-in rack structure, and its size completely matches the universal installation rack of the 3300 series. It supports direct plug-in installation, and the operations of disassembly, debugging, maintenance and replacement are simple. The on-site wiring is neat and orderly. The entire machine strictly follows the industrial electrical safety and electromagnetic compatibility standards for production. The enclosure has the ability to prevent dust and minor impacts. It can operate stably in conventional working environments such as industrial cabinets, central control rooms, and on-site control rooms for a long time. The module is powered by the power module of the 3300 series, and all electrical interfaces are standardized. It can be quickly connected to the system circuit and is compatible with various monitoring modules of the same series. The system expansion is flexible.

Function and Position

This module is a dedicated alarm relay output unit that can independently receive multi-level alarm signals issued by monitoring modules such as vibration, shaft displacement, and rotational speed. The internal multi-channel relay circuits are electrically isolated from each other and do not affect each other. It can precisely distinguish different types of signals such as warnings, dangers, and faults, and synchronously output passive switch contact signals. When monitoring parameters exceed limits, sensor failures, or line abnormalities trigger alarms, the relay can quickly complete the contact opening and closing actions. An external drive for sound and light alarmers, intermediate relays, PLC control systems, and unit safety interlock circuits can be connected to achieve on-site warnings, remote signal uploads, and equipment interlock shutdown functions. The module has a built-in self-check function for working status, which can provide real-time feedback on its own operation and contact status. It is mainly used in scenarios such as alarm signal conversion, local sound and light alarms, equipment safety interlocks, and signal remote transmission, improving the safety protection logic of the unit.

Core Performance Parameters

The module has high signal recognition accuracy and can stably match the alarm levels output by the same series of monitoring modules. The relay action response is rapid, and the signal transmission delay is low. The contact load parameters meet the requirements of industrial control circuits for regular use. The on-off performance is stable, and the mechanical and electrical lifespans are long. Internal integrated filtering and isolation circuits can effectively resist electromagnetic interference from on-site frequency converters, high-power motors, and high-voltage lines, preventing relay false triggering and false actions. The equipment supports 7×24-hour uninterrupted continuous operation and shows no significant performance degradation under long-term operation. The module has excellent electrical insulation performance, enabling effective isolation of the monitoring circuit from the control circuit, enhancing overall electrical safety. The working temperature and humidity range is suitable for industrial indoor and cabinet environments, with a wide tolerance range for temperature and humidity, and excellent environmental adaptability.

General Adaptable Accessories

For on-site installation and wiring, basic auxiliary materials such as control cables, shielded signal lines, standard terminal blocks, and line fixing clips can be used to meet wiring, connection, and cable fixation requirements. The system end is compatible with the 3300 series standard racks and power modules, and can be combined with vibration monitoring modules, shaft displacement monitoring modules, rotational speed monitoring modules, and other series of products. It can be flexibly configured according to the on-site alarm points and interlock requirements. The output side can be externally connected to sound and light alarm lights, intermediate relays, industrial control equipment, unit interlock protection circuits, etc. The module interfaces, terminal blocks, and vulnerable accessories all adopt the 3300 series general specifications, making spare parts procurement and replacement convenient. Routine inspections, function calibrations, and fault troubleshooting can be completed using conventional 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 extraction, and heavy equipment manufacturing, and is equipped on state monitoring systems of large and medium-sized rotating mechanical equipment such as steam turbine generators, gas turbines, centrifugal compressors, large fans, smoke gas turbines, high-pressure pump sets, and heavy gear machinery. It 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 and mining enterprises, providing alarm signal output, on-site alarm and safety interlock protection for the entire monitoring system, and helping the units operate safely and continuously.
