The enclosure has dust-proof and slight mechanical impact resistance protection performance. It can operate normally in conventional working environments such as industrial cabinets, central control rooms, and on-site control rooms. The module is uniformly powered by the same series power module. The electrical interface has a high degree of standardization, allowing for quick connection to the entire monitoring and control circuit. It is compatible with various monitoring modules and functional modules of the 3300 series, and the system expansion is flexible and convenient.

Function and Positioning

This module is a single-channel relay output unit, specifically used for processing system alarm signals. The equipment can receive real-time warning, danger and fault signals transmitted by various monitoring modules at the front end. The internal circuit identifies and processes the signals, then drives the relay contacts to complete the switching of on and off, outputting independent switch quantity signals. The internal circuit loop has an electrical isolation design, which can separate the monitoring signal circuit from the external control circuit, improving the system operation safety. When abnormal conditions such as monitoring parameter over-limit, sensor failure, circuit breakage, etc. occur, the relay can act quickly. An external drive sound and light alarm device, intermediate relay, PLC system, and unit safety interlock circuit can be connected to achieve local sound and light alarm, remote signal upload, equipment interlock shutdown, etc. The module is equipped with an operation status self-check function, which can provide real-time feedback on its own working status. It is mainly applied in alarm signal transfer, on-site fault indication, equipment safety interlock, operation status remote transmission, etc.

Core Performance Parameters

The module's signal recognition ability is precise, and it can stably adapt to 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 industrial control circuit usage specifications. The switching performance is stable, the mechanical life and electrical life are long, and it can meet the long-term continuous working requirements. The equipment integrates filtering and anti-interference circuits internally, which can effectively resist electromagnetic interference generated by large-power motors, frequency converters, and high-voltage lines, preventing the relay from triggering or operating incorrectly. The entire machine supports 7×24-hour uninterrupted continuous operation. During long-term operation, the performance of core components such as circuits and contacts does not show significant degradation. The insulation performance of the circuit is excellent, and the electrical isolation effect is reliable. The working temperature and humidity range is compatible with industrial indoor and cabinet environments, with strong temperature and humidity tolerance, and the overall environmental adaptability performance is outstanding.

General Adaptable Accessories

For on-site installation and wiring, basic auxiliary materials such as industrial control cables, shielded signal lines, standard terminal blocks, cable fixing clips can be used to meet the requirements of wiring, connection and line fixation. At the system integration level, it is compatible with the standard rack and power module of the 3300 series, and can be freely combined with vibration monitoring modules, shaft displacement monitoring modules, speed monitoring modules, etc., and be flexibly configured according to the alarm points and interlock logic at the site. The output end of the module can be externally connected to sound and light alarm devices, intermediate relays, industrial control systems, unit interlock protection circuits, etc. The product interfaces, terminal blocks, and common vulnerable accessories all adopt the 3300 series general specifications. The spare parts procurement and replacement process is simple, and daily inspection, function testing, and fault troubleshooting can be completed using common industrial electrician tools.

Applicable Equipment Domains The product is widely applied in industrial fields such as thermal power generation, petrochemical industry, metallurgy, coal chemical industry, oil and gas extraction, and heavy equipment manufacturing. It is also applied in the condition monitoring systems of large and medium-sized rotating mechanical equipment such as steam turbine generators, gas turbines, centrifugal compressors, large draft fans, flue gas turbines, high-pressure pump sets, and heavy-duty gear sets. It is mainly installed and arranged in places such as the main control cabinet rooms of power plants, control rooms of chemical plants, power generation machine rooms of metallurgy, and electrical cabinets of industrial and mining 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 power generating units.
