I-7551 Isolated RS-232 to RS-232 Repeater


• 3000 VDC 3-way Isolation Protection
• ESD Protection
• Baud Rate, 300 ~ 115200 bps
• DIN-Rail


The I-7551 provides a complete full-duplex (including control signal) electrical isolation channel between two RS-232 devices. This isolation is an important consideration if a system uses different power sources, has noisy signals, or must operate at different ground potentials.

The CTS/RTS pins of the I-7551 module can be reconfigured as DSR/DTR to meet requirements on different applications.

The I-7551 incorporates two DC-to-DC isolator, the isolation site of the I-7551 is located in the input and output interface circuit. In other words, the I-7551 is 3-way isolation RS-232 to RS-232 repeater.
