3onedata | SW485A | Industrial-grade RS-232 to RS-485 Converter
The SW485A is an industrial-grade interface converter that facilitates bidirectional data conversion between RS-232 and RS-485 serial ports without requiring an external power supply. It features high sensitivity and is equipped with 600W surge protection and 15kV electrostatic protection to prevent device damage. The RS-232 port uses a DB9 interface and can draw power from a PC's serial port via TXD, RTS, and DTR signal lines.
Specifications
- Serial Port: Supports EIA RS-232C and RS-485 standards with one RS-232 and one RS-485 port. The RS-232 port uses a DB9 female interface, while the RS-485 port uses a 4-pin terminal block.
- Transmission Distance: RS-232 up to 15m, RS-485 up to 1200m.
- Direction Control: Automatic data flow control for RS-485.
- Load Capacity: Supports 32-point polling, customizable up to 128 points.
- Interface Protection: 600W surge and 15kV electrostatic protection.
- Power Requirement: No external power supply needed; powered via RS-232 signals.
- Power Consumption: Static ≤10mA, Dynamic ≤40mA.
- Environmental Limits: Operating temperature -40 to 80℃, storage temperature -40 to 85℃, humidity 5% to 95% non-condensing.
- Physical Characteristics: Plastic housing, dimensions 71mm x 33mm x 16.5mm, weight 30g.
- Certification: CE, FCC, RoHS.
- Warranty: 3 years.
