Use the SEL-2910 Port Isolator to protect the EIA-232 ports of data terminal or data communications equipment from the effects of induced voltages. Increase data reliability by breaking the path for ground loops. If long runs of EIA-232 cables through harsh electrical environments are necessary, the SEL-2910 can provide the isolation you need. Powered directly from the data lines.
Protected EIA-232 Ports—Install the SEL-2910 on EIA-232 ports of data terminal or data communications equipment to protect equipment from the effects of induced voltages.
Improved Safety—Provide isolation to 2,500 Vrms.
Data and Time Codes—Isolate both EIA-232 and IRIG-B data channels where it is not feasible to use fiber-optic cable.
Uses power from the host device EIA-232 transmit data pin.
Isolates to 2500 Vrms.
Plugs directly onto DB-9 connector.
–40° to +85°C (–40° to +185°F). Meets or surpasses applicable IIEC and IEEE standards for temperature, humidity, vibration, sock and bump, seismic, electrostatic discharge and dielectric strength.
The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
