3. Key Features
3.1 Multi-Protocol Serial Communication
The module features 4 configurable RS-422/RS-485 channels, supporting both full-duplex and half-duplex operation to adapt to diverse industrial communication needs. With a maximum data rate of 10 Mbps per channel, it enables high-speed data transmission for applications like real-time sensor data collection and remote equipment control.
3.2 Precise Synchronization Capability
Equipped with external clock input (0–10 MHz) and high-accuracy internal clock (±50 ppm), the TPMC866-11 ensures precise synchronization across multiple serial channels and distributed modules. This is critical for applications like aerospace telemetry and industrial process control, where timing consistency directly impacts data integrity.
3.3 Robust Data Integrity
Each channel is equipped with 16 KB separate Tx/Rx FIFO buffers, preventing data loss during peak traffic periods. The module also integrates error detection mechanisms (parity check, frame error detection) to ensure reliable data transmission, reducing the risk of communication failures in harsh industrial environments.
3.4 Rugged Design & Safety Compliance
With 2.5 kV DC galvanic isolation and enhanced EMC performance, the module resists electromagnetic interference and voltage surges common in industrial settings. Its ruggedized design withstands extreme temperatures (-40°C–85°C) and high vibration, while SIL 2 certification ensures compliance with safety standards for critical control systems.
