Dtech DT-9000 RS232 to RS485 Industrial Serial Converter:
- Technical Specifications: Compatibility EIA/TIA RS-232C & RS-485 standards, DB9 female connector on RS232 side, 6-pin terminal block or DB9 male on RS485 side, baud rate range 300 bps to 115.2 Kbps, transmission distance RS232 up to 15 meters / RS485 up to 1.2 km (4,000 ft), operation mode asynchronous 2-wire half-duplex, port-powered technology (no external power supply required), operating temperature -20°C to +70°C.
- Bidirectional Signal Translation: Seamlessly converts standard point-to-point RS-232 serial signals into multi-drop noise-immune RS-485 differential signals.
- Long-Distance 1.2km Industrial Transmission: Extends communication distance up to 1,200 meters over twisted-pair copper wire across sprawling factory floors.
- Multi-Drop Networking (Up to 32 Nodes): Enables a single PC host to monitor and communicate with multiple remote RS485 PLCs, sensors, and meters.
- Port-Powered Zero-Configuration Plug & Play: Draws operating current directly from the RS-232 TXD, DTR, and RTS handshake lines without needing an external AC adapter.
- Built-in Surge & ESD Protection: Protects sensitive PC COM ports from industrial ground loop surges and electrical spikes.
- Applications: Factory PLC automation, building HVAC automation, SCADA energy monitoring, access control turnstiles, and POS receipt printers.
