2500Vrms RS232 To RS485 Serial Converter , PhotoElectric Isolation - Product

Other Specification :  2500Vrms RS232 To RS485 Serial Converter , PhotoElectric Isolation Isolation Degree: Isolation Voltage 2500Vrms 500DC Non-stop. Operation Mode: Asynchronous Half Duplex Or Asynchronous Full Duplex. Signal Indication: 3 Pilot Lamps For Power (PWR), Send (TXD) And Receive (RXD). Transmission Media: Twisted Pair Cable Or Shielded Cable. Description: Compatible With The Recommended Standards Of RS-232C, RS-422 And RS-485, UT-503 Photoelectric Isolation Interface Converter Can Convert The Single-ended RS-232 Signal Into Balance Differenced RS-422 Or RS-485 Signal. The Built-in Photoelectric Isolator Can Provide An Isolation Voltage Of As High As 250Vrms. Also, There Is A Rapid Transient Voltage Suppression Protector For Protection Of RS-422/RS-485 Interface With Advanced TVS(TRANSIENT VOLTAGE SUPPRESSOR) Technology Adopted. Under Normal Conditions, The TVS Tube Is In The State Of High Resistance. However, When Both Ends Of The TVS Tube Are Hit By A Transient High Energy, The Impedance At Both Ends Can Be Depressed By The TVS At A Very High Speed, And After Absorbing A High Current, The Voltage Between The Two Ends Is Suppressed And Kept At A Pre-set Value, Therefore No Damage Is Caused To The Electrical Components Behind By The Transient High Voltage Impact. The Protector Can Effectively Restrain Lightning Or ESD (electro Static Discharge) With A Protection Voltage Of 600W On Each Line For Lightning Surge And Surge Voltage Or Transient Over Voltage Possibly Caused Up By Various Reasons, And At The Same Time, A High-speed Transmission Of RS-422/RS-485 Interface Is Ensured By The Tiny Capacitance Between The Poles. Through A DB9 Female Connector RS-232 Interface Is Connected To Other Interfaces Compatible With RS-232C Standard, And For RS-422 And RS-485 Interfaces A 10PIN Male Connector Is To Be Used For Connection.
