Product description
The DT4227 UI process indicator converts analog measuring transducer signals into scaled readings in physical units for cabinet mounting. Any display range can be assigned to the selected input signal range. The unit features a 5-digit, 57 mm LED display readable at distance, adjustable brightness, and indicator LEDs for limit status. A 20 VDC supply output powers passive 4-20 mA transmitters. Two freely programmable relay outputs provide limit control with selectable limit modes. Configuration is performed using the three front-panel pushbuttons through a simple menu or via the USB-mini port and single-screen setup software for quick commissioning. Two power supply options cover DC and AC installations to match control cabinet requirements.
