I-7520 RS-232 to RS-485 Converter — Din-Rail Mount, Auto-Tuner, Auto Baud 300~115200 bps

Compact converter that bridges RS-232 to two-wire RS-485 (D+, D-) while mounting on a DIN rail. The RS-232 side uses a female 9 pin connector and the unit automatically selects baud rates from 300 ~ 115200 bps. An internal "Self Tuner" handles link configuration to simplify setup. Key specifications: - Input: RS-232 protocol to female 9 pin connector - Output: RS-485 protocol (two wire, D+, D-) - Auto Switching Baud Rate: 300 ~ 115200 bps (transmission speed up to 115200 bps) - Internal "Self Tuner" for automatic link tuning - Maximum of 256 modules in a single RS-485 network without using a repeater - Maximum of 2048 modules in a single RS-485 network when using a repeater - Repeater request: 4,000 feet or over 256 modules - Isolation voltage: 3000 VDC on the RS-232 side - 3000 VDC Isolation Protection on the RS-485 side - ESD Protection for the RS-232/422/485 data line - Power Input of +10 ~ +30 VDC - Supports Operating Temperatures from -25°C ~ +75°C Designed for industrial serial networking, the I-7520 delivers robust isolation, ESD protection and flexible auto-baud operation for reliable RS-232 to RS-485 conversion on DIN rail installations.
