Key benefits Durable construction: built with electronic components and precision manufacturing to ensure long term reliability. No external power needed: passive converter design requires no power supply for operation. Clear signal conversion and longer reach: converts a single ended PS232 signal to a balanced RS485 differential signal and extends communication distance to 1.2 kilometre. Broad compatibility: supports RS232C and RS485 standards for flexible integration. What it does Function: passive PS232 to RS485 converter that enables RS232 hosts to communicate on an RS485 network without additional power. Performance: provides reliable single to differential signal conversion with extended reach up to 1.2 kilometres. Compatibility: compatible with RS232C and RS485 standards to fit common legacy and fieldbus needs. Key specifications and features Input interface: PS232 (singleended) Output interface: RS485 differential Distance extension: up to 1.2 kilometre Power: passive; no external power supply required Standards: RS232C and RS485 compatible Use scenarios Scenario 1: A computer with an RS232 port (PS232) connects to a distant RS485 device at up to 1.2 km, enabling control and data collection across a large facility without powering the converter. Scenario 2: A legacy RS232 based instrument or controller is integrated into a modern RS485 network for centralized monitoring and supervisory control in an industrial setting. Scenario 3: A site with limited power access uses the passive converter to link a local PS232 host to multiple RS485 sensors or actuators distributed across a plant or warehouse, simplifying installation and reducing wiring needs. Notes The converter maintains a simple, power design while delivering reliable conversion from PS232 to RS485. It emphasizes compatibility with common RS232C and RS485 equipment, supporting straightforward integration into existing systems.
