DE38 is an LED display module. Universal display module with MODBUS-RTU interface. DE38-MODBUS is a universal, six-digit display compatible with devices with a MODBUS-RTU interface.

Due to its versatility, the device can work both in MASTER mode (as the master unit that polls measuring modules), or as SLAVE, as an extension for example for PLCs. The red, seven-segment high-resolution display with the number 38 mm makes the device widely used in industry, wherever we require a clear display of the measurement value.
