Description

The RS232 TO RS485 (B) can be widely used for point-to-point, point-to-multipoint, long distance cascaded communication network between two hosts, or between host and MCU/Peripheral. It also can be used in the application scenarios that require RS232 to RS485 conversion such as Industrial Automation and IoT

RS232 TO RS485 (B) is an industrial-grade rail-type active optoisolated RS232 to RS485 converter.

Applications:

Industrial Automation
Access control
Self services banking
Parking sevices
highway toll stations
Attendance system

Features:

Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal
Stable transmission at the rate of 300~115200bps
Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
Integrates optional RS485 output terminal 120R resistor, enabled/disabled via a switch
The onboard power supply screw terminal, allows 6V~36V DC wide range input
Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
