Rosemount™ 2180 Field Bus Modem
The Rosemount 2180 Field Bus Modem is used for connecting the TRL2 field bus from Rosemount Tank Gauging field devices or the Rosemount 2460 System Hub, to the Rosemount TankMaster PC in the control room.
It is connected to the PC using either the RS232 or the USB interface. The modem has LEDs to indicate power-on and communication, and if required front panel switches to set gain and termination. The mounting kit enables fitting to a standard DIN rail.
