CON (RS485 Master Network Interface)


The eBMS/IO TCP-CON, CON and CON-R modules provide a convenient means to connect power and either ethernet or 2-wire RS485 Modbus communications to one or more I/O modules without any extra wiring.

The IP20 rated modules may be plugged together with other modules on standard TS35 DIN rail or direct mounting.

The TCP-CON & CON module contains over-voltage protection on the power terminals and an electromagnetic interference (EMI) filter on the communications terminals. It also contains termination and bias resistors.

Delivery in approximately 2-5 working days (subject to availability)
