DT-9022I is an RS-232 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/RS485 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.
It provides reliable connection for point-to-point or point-to-multipoint communication.
Maximum 128 RS-485 interface devices can be supported for the point-tomultipoint communication. Data rate can be up to 300-115.2KBPS, and the power indicators and data traffic indicators can be used for error indication.
