DERELL DGI-99-R-B Technical Specifications
- Supply Voltage: 24V DC/AC (Maximum isolation voltage between inputs and supply is 40VAC).
- Display: Dual Row Display (4-Digit 7-Segment PV - Process Value, 4-Digit 7-Segment SV - Set Value).
- Calibration Scale: Adjustable between -1999 ... 4000.
- Decimal Point: Selectable position (2nd, 3rd, or 4th digit).
- Accuracy: ±0.5% of full scale (±1 Digit).
- Offset Value: -500 ... 500 (Used to compensate for signal losses).
- Hysteresis Adjustment: 1 ... 100 definable for both OUT and Alarm.
- Sensor Protection: If the analog input measurement fails or the signal is lost, OUT and ALARM outputs automatically switch to the OFF position.
Supported Input Signals & Impedances
The device supports the following selectable analog inputs via its parameter settings:
| Input Type | Input Impedance | Maximum Limit | Application Area / Notes |
|---|---|---|---|
| 0-10V DC | 100 kOhm | Max 20Vdc | For analog outputs of frequency inverters (VFD) and potentiometers. |
| 0-1V DC | 100 kOhm | Max 20Vdc | For very low voltages and humidity indicators. Loadcell cannot be connected directly. |
| 0-20mA DC | 10 Ohm (Shunt: 27 Ohm) | Max 50mA dc | For current outputs from inverters and various sensors. |
| 4-20mA DC | 10 Ohm (Shunt: 27 Ohm) | Max 50mA dc | For industrial sensors with a standard current loop. |
Output Features & Control Form
- Standard Outputs: 2 relay outputs are provided as standard.
- Relay Capacity: 250VAC, 2A on resistive load (NO + NC contacts). SSR output option is available.
- Control Logic: Operates on ON/OFF control logic. This model does not have PID functionality.
- Output Assignments: Outputs can be parametrically assigned to values such as alarm (high or low level), relative, or proportional. The control form can be selected as direct or reverse.
⚠️ Important Usage Notes & Warnings
No Sensor Power Supply Output: This device does not have an internal voltage output (+VDC) to power external sensors. For applications requiring power (such as pressure transmitters or potentiometers), an external 12/24VDC power supply must be used in the panel, or a DEIP series product with built-in sensor supply should be preferred.
- Stable and Reliable Operation: Thanks to its advanced value-reading algorithm, the annoying digit flickering in the right-most digits of the display—commonly caused by interference in standard indicators—does not occur in this device.
- Industrial Protection (Galvanic Isolation): It features galvanic isolation allowing it to work side-by-side with high-noise potential devices such as power supplies, frequency inverters, and servo drives in the same panel.
- Installation Warning: Installation procedures must be carried out ONLY by expert technical personnel in accordance with the relevant directive (2006/42/EC). Connections contrary to the instructions may void the device's warranty.
