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

Product Description
This converter converts a V.24 (RS-232) interface into a 20 mA TTY current loop interface bidirectionally. The interference immune TTY signal
allows problem-free data transmission over distances of up to 1000 m using a twisted-pair and shielded 4-wire cable.

Your advantages
• Mounting on standard EN DIN rails
• Transmission distances of up to 1000 m in active TTY mode
• High-quality 3-way isolation up to 2 kV (VCC // RS-232 // TTY)
• In the case of variable cable lengths, the TTY 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
• Conversion of RS-232 TxD/RxD full duplex data signals to the TTY current loop standard
• Semi-active, active or passive TTY mode, depending on pin assignment
• 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
• RS-232 connection via 9-pos. D-SUB and standard RS-232 cable
• Transmission speed of up to 19.2 kbps
• Shipbuilding approval in accordance with DNV GL
