- Raven Haznet RS485 IS Safety Barrier

The Raven allows safe communication via its RS-485 port to a Hawk that is mounted in a hazardous location. Certified by CSA it will prevent the possibility of explosion by keeping out up to 220 volt AC in a DIV2 zone from reaching Hawk if something fails.The Raven has three interface ports, USB, RS232 and half duplex RS485. This allows it to be hooked to almost anything with some kind of serial port such as a laptop, PLC or SCADA system withoug resorting to a expensive to implement fieldbus such as Profibus. Standard serial protocols like modbus can then be used since the Raven is protocol independant.

CalScan also carries a model that is USB only in a ruggadized case. The is typicaly used by testers in the field that are using a wirred communication interface to the Hawk or other compatible RS485 port.
