The advanced series digital indicator is the DERELL DGI-77-R-A, powered by a 220V AC supply. The product has a panel size of 72x72mm. Mounting dimensions can be reviewed on the product image.

Supported input signals:

• (0-10V) >> Typically used for analog outputs of speed controllers. Can measure any 0-10V DC and connect directly to inverter potentiometers.
• (0-1V) >> Ideal for load-cell or humidity signal inputs. Note: Load-cells cannot be directly connected.
• (0-20mA) >> Measures analog current signals from inverters and sensors.
• (4-20mA) >> Standard current input support.

Calibration of all input data is supported, including decimal placement and signal filtering. This model includes 2 standard relay outputs with configurable behavior (alarm, high-low threshold, etc.). Outputs function with ON/OFF logic (no PID control). You may define hysteresis and offset for stability and accuracy.

Model Variants:
- DGI-77-R-B (24V AC/DC version)
- DGI-44-R-A (48x48mm version)
- DEIP-37 (37x72 horizontal compact version)

Note: This model does not include sensor supply output. If your sensor requires +VDC power, consider an external power supply or choose a compatible DEIP model.

++ The DGI-77-R-A is manufactured for harsh industrial environments. Designed with galvanic isolation, it performs reliably even near power supplies, inverters, and servo drives.

Editor's Note: This model combines the practicality of a dual-line display and the power of two programmable relay outputs. Designed for reliability and stability, it eliminates the common display jitter problems. A dependable solution for your analog monitoring and control needs.
