Our General Terms of Use for Downloads are valid (http://phoenixcontact.com/download) 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 highquality 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 DNVGL Key Commercial Data Packing unit 1 pc GTIN GTIN 4017918188795 Weight per Piece (excluding packing) 181.200 g Custom tariff number 85176200 Country of origin Germany 03/28/2021Page1/8 https://www.phoenixcontact.com/us/products/2744461 Interface converter-PSM-ME-RS232/RS232-P-2744461 Technical data Note Utilization restriction EMC: class A product, see manufacturer's declaration in the download area Use in potentially explosive areas is not permitted in China.
