Process and Temperature Controllers   Overview The innovative range of 3200 controllers offer precision control of temperature and other process variables together with a host of advanced features not normally found in this class of controller. The emphasis is on ease of use. A simple ‘Quick Start’ code is used to configure all the functions essential for controlling your process. This includes input sensor type, measurement range, control options, and alarms, making ‘Out the Box’ operation truly achievable. In operator mode every parameter has a scrolling text message describing its function and is available in English, German, French, Spanish or Italian. More advanced features are configured using iTools, a PC based configuration wizard which is an easy to use and instructive guide to all the functions in the controller.       Technical Specification   General Environmental performance Temperature limits Operation: 0 to 55°C Storage: -10 to 70°C Humidity limits Operation: 5 to 90% RH non condensing Storage: 5 to 90% RH non condensing Panel sealing: IP65, Nema 4X Shock: BS EN61010 Vibration: 2g peak, 10 to 150Hz Altitude: <2000 metres Atmospheres: Not suitable for use in explosive or corrosive atmosphere Electromagnetic compatibility (EMC) Emissions and immunity: BS EN61326 Electrical safety (BS EN61010): Installation cat.
