📋 Product Description
High-Precision Monitoring: The display controller is suitable for measurement and control of various temperatures, pressures, liquid levels, and lengths. Adopting a microprocessor for digital operation, it ensures high precision linear correction for various non-linear signals.

The light column display controller combines digital measurement display and analog measurement display in one. It utilizes a digital LED display for accurate real-time values, while the high-precision 40-line light column provides an intuitive visual comparison of parameters.

Features an open interface for internal parameter settings including input type, operation mode, output, and communication parameters. The advanced jumperless technology allows for online index number changes without powering off the device.
