Alstom MAE99-04 Isolation Unit Module
Introduction: Alstom MAE99-04 (formerly Converteam) is an 8-channel serial interface isolation unit dedicated to industrial DCS/PLC systems, which achieves electrical isolation of input/output/power supply, blocks ground potential difference and electromagnetic interference, and ensures stable serial communication and equipment safety.
1. Model MAE99-04, Alstom original factory, officially named 8CH serial I/F isolation unit.
2. 8 independent isolation channels, supporting bidirectional isolated transmission of RS-232/RS-485/RS-422 serial signals.
3. Optoelectronic+magnetic isolation composite technology, isolation voltage ≥ 2500Vrms, strong resistance to common mode interference.
4. The maximum communication speed is 115.2kbps, suitable for industrial low-speed to medium speed data exchange.
5. 24VDC power supply, wide voltage range of 18-30VDC, compatible with industrial control system standard power supply.
6. 3U standard card structure, metal shielding shell, anti vibration, anti EMC interference.
7. Each channel has independent LED status lights that display real-time communication, fault, and power status.
8. The input/output/power supply terminals are completely isolated, effectively eliminating ground loop interference.
9. Support multi-channel parallel operation to meet the isolation requirements of serial networking for multiple devices.
10. Industrial wide temperature design, suitable for harsh on-site environments such as power, metallurgy, and chemical engineering.
11. Standard cabinet rail installation, plug-in wiring, easy maintenance and replacement.
12. Compact design, weighing approximately 2kg, saving installation space inside the cabinet.
13. Built in signal verification and fault self checking, quick identification of anomalies, and reduced downtime risk.
14. Compatible with Alstom (Converteam) series DCS and PLC systems, with strong adaptability.
15. Widely used in industrial automation communication isolation scenarios such as power, metallurgy, oil and gas, water treatment, etc.
Conclusion: MAE99-04, with its core advantages of high isolation and voltage resistance, multi-channel parallelism, strong anti-interference, and stable reliability, is the core unit for industrial serial communication isolation and signal security transmission.
