The CPU's conformal coating protects against humidity, salt spray, and dust. The wide temperature range ensures reliable startup and operation in cold climates and hot enclosures without additional heating or cooling. The unit is also tested for high altitude operation (up to 4000 m) and meets IEC 60068-2 standards for vibration and shock.
Despite its rugged construction, the CPU offers the same programming features as standard AC500 CPUs: Automation Builder with CoDeSys V3, Modbus TCP/RTU, CANopen, and up to 16 tasks. The Ethernet port supports web server, FTP, and SNMP for remote diagnostics.
This CPU is ideal for oil and gas installations, solar tracking systems, wind turbine control, agricultural machinery, and outdoor pumping stations. It is also used in military vehicles and railway signaling equipment where extreme temperatures and vibration are common.
