UT-509 is a repeater with optoelectronic isolation. It complies with RS-422 and RS-485 standards; it extends the communication distance of RS-422/RS-485 BUS networking, increases the quantity of RS-422/RS-485 networking devices. The built-in optoelectronic isolator and DC/DC isolated module can provide as high as 2,500Vrm isolated voltage; the fast instant voltage restraint is designed to protect RS-422/RS-485 interface; it adopts advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) instant voltage restraint; normally, TVS tube is in high impedance state; when both sides of TVS tube suffer from high power impact in a sudden, the voltage restraint will fast lower the impedance from both sides, and absorb in big current; with this, the voltage on both sides are fixed at presupposed value, protects the component of circuit from damage. This voltage restraint provides 600W each wire with lightning and ESD protection, and surge voltage and instant overvoltage protection on circuit which causing by all reasons; the tiny interelectrode capacitance ensures high speed transmission for RS-422/485 ports. Both RS-485 input & output adopt terminal block connector.
This repeater is with built-in zero delay auto receiving and transmitting conversion and unique I/O circuit auto control data flow direction without any handshake signal (RTS, DTR); there is no need jumper wire setting for full duplex (RS-422) and half duplex (RS-485) mode, plug & play.
UT-509 optoelectronic isolated repeater provides connection for point to point, point to multipoint communication. For point to multipoint mode, each repeater is allowed to connect 128 sets RS-422 or RS-485 devices with baud rate 300-115.2Kbps. The power and data flow indicators indicate the working status.
