4. Functionality
The WT13411 functions as a dual-port communication interface card that enables a PC to communicate with devices using the 20mA current loop (TTY) standard. Each port can operate independently, allowing simultaneous communication with two separate devices or systems.
Operating Principle:
The 20mA current loop interface transmits data by modulating current flow rather than voltage levels, providing superior noise immunity and allowing for longer cable runs compared to traditional RS-232 interfaces. The WT13411’s isolated design ensures that each communication channel is electrically separated from the host system, preventing ground potential differences and protecting against electrical faults.
Use Cases and Applications:
- Industrial automation systems and programmable logic controllers (PLCs)
- Legacy equipment interfacing (e.g., CNC machines, process controllers)
- Laboratory instrumentation and measurement systems
- Telecommunication and data acquisition systems
