The rdc232Enet safely and easily connects an 
industrial device with serial interface (RS-232) to 
an Ethernet network while providing the ultimate 
in isolation, surge, and noise protection. The 
RS-232 port and network port are isolated from 
each other, as well as the DC supply ground. 
600w transient suppressor diodes further protect 
the RS-232 port from momentary surges. 
Standard industrial automation protocols like 
Modbus/TCP is also supported.

Isolation, industrial design, small size, DIN rail 
mount, user indication, and wide range DC 
supply make the rdc232Enet a very engineer- 
friendly device for your industrial data 
communication system.
