Interface converter, for converting RS-232 (V.24) to RS-422 (V.11) and RS-485, with electrical isolation, 2 channels, rail-mountable 

## Why buy this product 

- RS-422 4-wire point-to-point operation 

- RS-485 2-wire operation, half duplex 

- RS-485 4-wire operation, full duplex 

- Automatic RS-485 transmit/receive changeover 

- Transmission speed of 4.8 kbps to 115.2 kbps 

- Integrated data indicator for dynamic indication of transmit and receive data 

High-quality 3-way isolation between power supply, RS-232, and RS-422/RS-485 for safe decoupling of potentials with 2 kV Integrated surge protection with transient discharge to the DIN rail
