Interface converter, for the isolation of RS-232 (V.24) interfaces, 4 channels, rail-mountable 

## Product Features 

- Mounting on standard EN DIN rails 

- In the case of variable cable lengths, the RS-232 connection on the field side can be established conveniently using plug-in screw terminal blocks 

- High-quality 3-way isolation up to 2 kV (VCC // RS-232 // RS-232) 

- Integrated surge protection with transient discharge to the DIN rail 

- Maximum transmission speed of 115.2 kbps 

- Transmission of TxD/RxD data channels and RTS/CTS control lines 

- 24 V DC or AC power supply suitable for the control cabinet 

- Active data transmission indicated by separate data indicators for the transmit and receive channels
