Ruggedised PLCs control sedimentation process

The harsh environment at Kittila poses no problem for the XC PLC which can operate in temperatures from -30˚C, with reliable system start-ups in temperatures as low as -40˚C, more than meeting the problems that might arise. Its circuit boards have a conformal coating to protect against moisture ingress.

The PLC is protected against vibration and shock and will tolerate a lot of mechanical stress – such as accelerations up to four g from random vibrations up to 500 Hz, or two g from sinusoidal vibration.
