About this item

  • Extended-Range Communication:RS-485 transceiver chip enables serial data transmission over 4000ft (1200m) with slew rate limiting technology for noise-free long-distance operation.
  • High-Speed Data Transfer:Achieves 2.5Mbps half-duplex communication through optimized TTL/RS-485 conversion, supporting simultaneous bidirectional data flow across industrial networks.
  • Multi-Device Network Architecture:Configure up to 32 modules in daisy-chain topology with repeater mode extension capability, ideal for industrial-control systems and EMI-sensitive applications.
  • Industrial-Grade Reliability:5V operating voltage with 120-500µA ultra-low power consumption, featuring short-circuit protection and thermal shutdown circuitry for failsafe 24/7 operation.
  • Universal Hardware Integration:0.1" header pins compatible with breadboards and PCB prototyping, paired with 5.08mm screw terminals for secure RS-422/485 cable connections.
