Port Isolator
SEL-2910
Port Isolator
Isolate and protect 9-Pin RS-232 ports from destructive induced voltages.
Use the SEL-2910 Port Isolator to protect the RS-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 you
have to have long runs of RS-232 cables through harsh electrical environments,
the SEL-2910 can provide the isolation you need. Powered directly from
the data lines.
