The entire machine is strictly manufactured in accordance with industrial electrical safety and electromagnetic compatibility standards. The enclosure has basic protective capabilities against dust and slight mechanical collisions, and it can operate stably in conventional industrial environments such as industrial cabinets, central control rooms, and on-site control rooms. The module is centrally powered by the same series power module, and all electrical interfaces are standardized, enabling 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.

Function and Positioning

This module is a dedicated alarm relay output unit. It can independently receive multi-level alarm instructions issued by the front-end monitoring module. The internal relay circuits are electrically isolated from each other, and their operations do not interfere with each other. When the monitoring parameters exceed the preset safety threshold, sensor failure, line abnormalities, etc., trigger an alarm, the module can quickly drive the internal relays to complete the contact opening and closing actions, and output an inductive switch signal. This signal can be externally connected to sound and light alarms, intermediate relays, PLC control systems, and unit safety interlock circuits, achieving local sound and light warnings, remote signal upload, equipment interlock shutdown, and other functions. The module is equipped with a status self-check function, which can real-time feedback its own operating status and contact conditions. It is mainly applied in scenarios such as alarm signal conversion, on-site fault indication, equipment safety interlock, and operation signal remote transmission, improving the logic of unit operation safety control.

Core Performance Parameters

The module accurately recognizes alarm level signals and can perfectly match the output signals of the same series monitoring modules. The relay actions respond quickly, and the signal transmission delay is extremely small. The contact load parameters comply with the standards for industrial control circuits, have stable switching performance, a long mechanical life and electrical life, and meet the requirements for long-term high-frequency operations. The internal circuitry integrates filtering and isolation circuits, which can effectively shield electromagnetic interference generated by frequency converters, large power motors, and high-voltage power supply lines, preventing relay false triggering and misoperation. The equipment supports 7×24-hour uninterrupted continuous operation and shows no significant degradation in circuit and contact performance during long-term service. The insulation strength of the circuit meets the standard, effectively isolating the monitoring signal circuit from the external control circuit, enhancing the overall electrical safety level of the system. The working temperature and humidity range is compatible with industrial indoor and cabinet environments, with a wide tolerance range for temperature and humidity, and outstanding environmental adaptability.

General Compatible Accessories

For on-site wiring construction, basic auxiliary materials such as control cables, shielded signal lines, standard terminal blocks, and cable fixing clips can be used to meet the needs of wiring, connection, and line fixation. In terms of system integration, it is compatible with the standard racks and power modules of the 3300 series and can be flexibly combined with vibration monitoring modules, shaft displacement monitoring modules, speed monitoring modules, and other series of products according to the on-site alarm points and interlock logic requirements. 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 components all adopt the general specifications of the 3300 series, making spare parts procurement and replacement convenient. Daily inspection, function calibration, and fault troubleshooting can be completed using common industrial electrical tools.
