UT-502,Protocol Converter,RS-232/RS-485/2 Port Industrial Photoelectric Isolated Interface - Product

Other Specification :  UT-502,Protocol Converter,RS-232/RS-485/2 Port Industrial Photoelectric Isolated Interface Description: UT-502 Is An RS-232C And RS-485 Compatible Industrial Photoelectric Isolated Interface Converter Designed To Convert A Single-end RS-232 Signal To A Double Balanced Differential 2 Port/RS Signal. The Built-in Photoelectric Isolator Can Provide Isolating Voltage Up To 2500Vrms And It Has A High-speed Transient Voltage Supress Or Which Is Designed To Protect The 2 Port/RS-485 Interface. The Advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) Presents A High-impedance State Under Normal Conditions, And It Can Fast Reduce The Resistance Across Two Ends While It's Withstanding Transient High-power Impulse So As To Absorb The High Current And Clamp The Voltage Across It To A Preset Value, Thus Prventing The Components In The Next Stage From Being Damaged. This Suppressor Can Supress Lightning And ESD (electro-static Discharge) With Lightning Surge Protection Power Of 600W For Each Line As Well As Surge Voltage And Transient Over-voltage On The Lines Cuased For Any Reason. Very Small Inter Electrode Capacitance Can Ensure High Speed Data Transmission Of RS-485 Interface. RS-232 Side Is Connected To RS-232C Compatible Interface Through A DB9 Female Connector, And RS-485 Side Is Connected To A 10-bit Wiring Terminal. The Converter Equips With Automatic Data Transceiver Without Delay, And The Unique I/O Circuit Can Automatically Control The Direction Of Data Flow Without Any Handshake Signal (such As RTS/DTR). Both 2-port Photoelectric Isolated Half-duplex (RS-485) Mode Switch Without Jumper Setup And Plug&play Can Be Achieved. This Converter Can Support Any Existing Communication Software And Interface Hardware, Eliminating The Need To Change The Software For Previous RS-232 Based Operation Mode.
