Rugged PLC operates from -30 to +70ºC
This typically reduces system building costs by eliminating the need for sophisticated protective enclosures with special seals, HVAC, shock absorbers, EMC protection, etc.
AC500-XC PLCs run exactly the same program code as the company’s AC500, allowing users to migrate to more robust solutions easily, and simplifying development for large systems that require control systems for both standard and extreme conditions. The mechanical dimensions and electrical specifications of connections are also the same as the standard AC500, allowing existing panel layouts and wiring harnesses or designs to be re-used. Extended temperature operation allows the PLCs to operate in temperatures from -30 to +70ºC, with reliable system start-ups in temperatures as low as -40ºC.
With few limitations, the AC500-XC operates at up to 70 C. Circuit boards are conformally coated to protect against high humidity levels. The PLC has extended immunity against salt mist and atmospheres with corrosive gases such as H2S, SO2, CL2 and NO2. High levels of vibration and shock can be tolerated, with accelerations up to 4 g from random vibrations up to 500 Hz, or 2g from sinusoidal vibration. The PLC is capable of operating at altitudes up to 4,000 m. It also offers extended EMC protection against voltage surges and fast transients, as well as electrostatic discharge.
