This product is a shunt diode safety barrier manufactured by MTL (UK). The detailed information is as follows:
- Manufacturer: MTL (United Kingdom)
- Place of Origin: United Kingdom
- Product Type: Shunt Diode Safety Barrier
- Weight: 1000g
- Warranty Period: 12 months
- Channel Design: It is a 4-channel safety barrier, but also supports configuration of 1 to 4 channels. The number of channels can be flexibly selected according to actual needs to meet different signal transmission requirements.
- Signal Processing: Mainly used for signal processing of thermocouples, low-level AC signals, and 4-wire RTDs (Resistance Temperature Detectors). It can effectively isolate hazardous areas from safe areas, ensuring the safety and stability of signals during transmission.
- Easy Installation & Maintenance: Adopts a compact and robust housing design, enabling convenient installation and simple daily maintenance. It can adapt to various installation requirements in industrial environments.
- Safety Description: 9V, 75Ω, 120mA
- Polarity: AC (Alternating Current)
- Maximum Voltage: Maximum voltage at 10μA (Vwkg): 250V; Maximum operating voltage (Vmax): 250V
- Fuse Rating: 250mA
- Matching Power: 50mW
- Process Control: In process control systems of industries such as chemical engineering, petroleum, and natural gas, it is used to connect sensors/actuators in hazardous areas with control systems in safe areas, ensuring the safe and stable operation of production processes.
- Industrial Automation: In industrial automated production lines, it can transmit various detection signals and control signals from hazardous areas to controllers and monitoring equipment in safe areas, realizing automated control and monitoring of production processes.
- Measurement & Testing: In scenarios requiring measurement and testing in hazardous areas (e.g., liquid level measurement and pressure measurement of hazardous chemical storage tanks), it can safely transmit measurement signals to measuring instruments and testing equipment in safe areas.
- Safety Systems: Used to connect safety sensors in hazardous areas (such as flame detectors and gas detectors) with alarm systems and safety control equipment in safe areas, ensuring timely and accurate alarm signals and corresponding safety measures when hazards occur.
- RTD (Resistance Temperature Detector): The international standard name for resistance temperature detectors, a common temperature-sensing element in industrial measurement, retained as an abbreviation to conform to the concise expression of industrial technical documents.
- Vwkg: A professional term in intrinsic safety standards, referring to the "maximum voltage that the safety barrier can withstand under specified fault conditions" (consistent with IEC 60079-11 intrinsic safety system specifications), retained as-is to ensure technical accuracy.
- MTL: The official name of MTL Instruments (a global leading brand in intrinsic safety and industrial protection products), retained to maintain consistency with the manufacturer's international brand title.
