About This Item
Overview
Details
Model BB-9POP4 isolates and protects RS-232 equipment from lightning surges, accidental high voltage shorts and ground loops. RS-232 data signals TD, RD, RTS, and CTS support up to 230.4 kbps. Isolation circuits are 2.5 kV rated and protects valuable equipment while maintaining maximum uptime.The isolator uses DB9 male and DB9 female connectors. The female connector is wired as a DCE and should be connected to a DTE port. The male connector is a DTE and should be connected to a DCE port. If you are connecting a DTE to a DTE or a DCE to a DCE, you will need a null modem adapter.
Each side of the isolator receives power from a single 12 VDC power supply to maintain isolation. This powering configuration allows the device to be used in a system with only one power supply, regardless of the power provided by the RS-232 ports.
A recommended, tested and certified power supply is available from Advantech and sold separately. (Note: using any other power supply may bypass or degrade the isolation barrier.)
