Modems and Routers for SCADA communication
industrial modems and routers support a wide range of protocols used for SCADA
communications protocols such as Modbus RTU, Modbus ASCII, Modbus TCP,
are equipped with an RS232C port and an RS485 port for
integration on any RS485 bus, 2-wire or 4-wire. Depending on the model,
also Ethernet and USB ports are avaialble.
for operating temperature ranges from -25°C to +70°C, some for -40°C to +75°C.
units are powered directly from low voltage DC (up to 72Vdc) or AC (up
to 30Vac) voltages.
Powering from 100..240Vac mains power is by means of an external power supply or low voltage AC transformer.
modem range consists of modems for ADSL/VDSL2, analogue leased lines, copper
cellular mobile networks, dial-up
lines, radio links and power lines.
