The PMA Digital 280 is a digital indicator with a 4-digit red or green display. It features universal input and input signal correction, freely scalable display, two relay outputs, RS422/485 interface, and analog output. It is suitable for displaying temperatures, pressures, or other physical parameters in industrial applications.
The PMA Digital 280 is a universal digital indicator designed for industrial applications where temperatures, pressures, or other physical parameters need to be displayed. It features a universal input circuit capable of connecting thermocouples, resistance thermometers, and sensors with voltage or current output without requiring plug-in modules or configuration jumpers. The device allows for input signal scaling, limit monitoring, and provides two relay outputs for alarm signaling.
