Interface converter, for the isolation of RS-232 (V.24) interfaces, 4 channels, rail-mountable
Product Description
A considerably higher level of immunity to interference can be achieved in industrial applications by using V.24 (RS-232) isolator modules. The high-
quality 3-way isolation results in an electrically isolated and interference-proof V.24 (RS-232) interface. This decoupling also protects the expensive
terminal devices against damage.
Your advantages
Mounting on standard EN DIN rails
High-quality 3-way isolation up to 2 kV (VCC // RS-232 // RS-232)
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
Integrated surge protection with transient discharge to the DIN rail
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
Maximum transmission speed of 115.2 kbps
Shipbuilding approval in accordance with DNVGL
