The HC900 hybrid controller is an advanced process and logic controller with data acquisition. A large screen, factory-floor operator interface provides users with local trending and data archiving capabilities with a wide selection of over 100 operator friendly preformatted displays and direct access display keys. The controller is a modular, scaleable platform available in three rack sizes (4, 8 and 12 I/O slots). To maximize installation flexibility, up to 4 remote I/O racks may be connected to a single controller to reduce wiring and installation costs. A variety of analog and digital modules are available to support up to a total of 256 I/O points, and up to 128 universal analog inputs minimize the number of input cards and spare parts required.
