EIA-232 to EIA-485 Interface—Connect a device that has an EIA-232 port to an EIA-485 network to communicate with DNP3, Modbus, or SEL Distributed Port Switch LMD protocols. Or, connect a computer to an EIA-485 port on a relay with an SEL-2886.
Easy Application—Select operating modes (EIA-422, RTS, or SDC), key the transmitter on and off, and control the echo mode. The SEL-2886 receives 5 Vdc power from the host device EIA-232 port or from an external adapter via a jack.
Improved Safety—Provide isolation to 1,500 Vrms.
Flexible Power Options
Use power pins in the host device EIA-232 port, or provide power through the power jack.
Provide isolation to 1,500 Vrms.
Plug directly onto a DB-9 connector.
Use control (DIP) switches to select operating modes to key the transmitter on and off and to control the echo mode.
Rely on an operating temperature range of –40º to +85ºC (–40º to +185ºF).
