Overview:
This industrial-grade optically isolated repeater combines signal receiving/amplifying with RS485-to-RS422 conversion. Compliant with RS-422 and RS-485 standards, it extends the communication distance of RS-422/RS-485 bus networks and increases the number of networkable devices. Its built-in optical isolator and power isolation module provide up to 2500Vrms isolation voltage. Fast transient voltage suppression protectors built in at both ends of the interface quickly and effectively protect the RS-422/RS-485 interface while strongly suppressing lightning and static, providing 600W surge protection per line against lightning surges, surge voltages and transient overvoltages of various causes. The RS-422 and RS-485 input/output terminals use all-copper binding posts as connectors. The converter has a built-in zero-delay auto transmit/receive switch that requires no handshake signals (such as RTS or DTR) and no jumper settings, achieving plug-and-play conversion between full-duplex (RS-422) and half-duplex (RS-485) modes.
The industrial-grade optically isolated interface converter can reliably be used for point-to-point and point-to-multipoint communication. In a point-to-multipoint network design, in principle each repeater can connect up to 128 RS-422 or RS-485 terminal devices; the actual number depends on the specific network design. The data communication rate is 300-115.2 kbps, with power and signal indicator LEDs that show whether the device communication is normal.
