MTL4532 is a pulse isolator with multiple functions and features, suitable for signal isolation and transmission in hazardous areas. The detailed information is as follows:Single channel, fully floating (Note: "Fully floating" means the input, output, and power supply circuits are mutually isolated without a common ground, which can effectively eliminate ground loop interference and improve anti-interference performance of pulse signal transmission)
- Supports switches or proximity detectors (compliant with NAMUR/BS EN 60947-5-6:2001 standards).
- Compatible with 2-wire or 3-wire voltage-type or pulse-type transmitters.
- For switch installation location: Suitable for Zone 0, Gas Group IIC, Temperature Class T6 hazardous areas.
- For proximity detector or transmitter installation location: Suitable for Zone 0, Gas Group IIC, Temperature Class T4-T6 (if properly certified), Division 1, Group A hazardous locations.
- NAMUR/BS EN 60947-5-6:2001: NAMUR is a standardization organization for process automation; BS EN 60947-5-6:2001 is a British-adopted European standard for "Low-voltage switchgear and controlgear - Part 5-6: Control circuit devices and switching elements - Proximity devices". These standards specify technical requirements for proximity detectors and switches in industrial hazardous areas, ensuring device compatibility and safety.
- Zone 0 / Gas Group IIC / Temperature Class T4-T6: Standard classifications for explosive hazardous areas per IEC/GB standards:
- "Zone 0" refers to areas where explosive gas mixtures are continuously present or present for long periods;
- "IIC" is the highest gas group, covering highly explosive gases such as hydrogen and acetylene;
- "Temperature Class T4-T6" defines the maximum surface temperature of equipment (≤135℃ for T4, ≤85℃ for T6), preventing high temperatures from igniting combustible media.
- Division 1 / Group A: Classifications in the North American hazardous area standard (NFPA 70 NEC):
- "Division 1" means explosive gas mixtures may exist under normal operating conditions;
- "Group A" refers to acetylene (a highly explosive gas), indicating the device is suitable for the most hazardous gas environments in North American standards.
- 2-wire/3-wire Transmitter: Common types of industrial pulse transmitters:
- "2-wire transmitters" share power and signal lines, with simple wiring;
- "3-wire transmitters" have separate power and signal lines, suitable for high-power or high-precision pulse signal transmission.
