RS232 To RS485 Converter Isolated Interface Asynchronous Half-duplex

RS-485 half-duplex connection

Isolation voltage: continuous 2.5KVrms /500VDC isolation

Communication distance: 0-5 KM(115200bps-9600bps)

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.

UT-502 industrial photoelectric isolated interface converter can provide reliable connection for point-to-point or point-to-multipoint communication.Maximum 128 RS-485 interface devices can be supported for the point-to-multipoint communication. Data rate can be up to 300-115.2KBPS, and the power indicators and data traffic indicators can be used for error indication. RS-232 to 2-port/RS-485 conversion is supported.
