It offers 3000 VDC optical isolation and is fully compatible with PC serial COM ports. The device supports data rates up to 115.2 Kbit/s, includes status LEDs, and comes in a compact black housing designed for industrial environments.
Advantages
This hardware converter requires no software and provides robust electrical protection with 3000 VDC isolation, 15 kV ESD protection on all signals and surge protection for RS-422/485 lines. It supports automatic direction toggling by hardware, terminal resistance and echo mode, and offers DIP switches for terminal settings. The built-in surge protector and wide DC input range (10–30 V) increase operational reliability in industrial installations.
Suitable for
Connecting legacy RS-232 devices to RS-422 networks
Integrating serial equipment into RS-485 fieldbus systems
Industrial automation and control cabinets (DIN rail mounting)
Environments requiring galvanic isolation and ESD protection
