The ICPCON I-7520 is an RS-232 to RS-485 converter for marine control system wiring, linking an RS-232 master port to an RS-485 slave network. It handles baud rates from 300 to 115200 bps with a variable data format and switches RS-485 direction automatically. The RS-232 side carries 3000 V DC isolation, and ESD protection to IEC 61000-4-2 covers the RS-232/422/485 data lines. Power is taken from a 10-30 V DC input at 1.2 W, and a single LED shows power and communication status. The operating range is -25 to +75°C. It is supplied new without box.
