The advanced series digital indicator is the DERELL DGI-99-R-A, powered by a 220V AC supply. The product has a panel size of 96x96mm. 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. 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, relative/proportional logic, etc.).
Outputs function with ON/OFF control logic. PID control is not supported, but hysteresis and offset options are available for fine tuning.
If analog measurement fails, outputs are disabled automatically for safety.

Relay Outputs: NO + NC, 250VAC, 2A (resistive load, SSR optional)
Alarm Modes: Absolute, Relative, Band, with hysteresis (1–100 steps)
Offset: -500 to +500

Model Variants:
- DGI-99-R-B (24V AC/DC version)
- DGI-77-R-A (72x72mm compact model)
- DGI-44-R-A (48x48mm panel model)

Note: This model does not include a sensor power supply. If your sensor (e.g. pressure transmitter or potentiometer) requires +VDC supply, you must use an external power supply or choose a compatible product from the DEIP Series.

++ The DGI-99-R-A is designed specifically for harsh industrial conditions. Its galvanically isolated design allows reliable use near noisy devices such as power supplies, frequency inverters, and servo drives.

Editor's Note: Dear friends, the DGI Series is a powerful controller with 2 relay outputs and dual-line display. It displays both the set value (SV) and the measured value (PV) simultaneously. What sets this device apart is its remarkable display stability. There are no flickering digits or unstable visuals. Its internal processing algorithm ensures fast, reliable, and steady operation. Though priced slightly above our other series, this model becomes even more economical thanks to its built-in 2-relay logic and simultaneous dual-display feature. Highly recommended for precision applications.
