6. Installation and Wiring
6.1 Panel Mounting
The IDC-S1RH is designed for panel mounting. Create a cutout in your panel with dimensions of 45mm x 45mm (1.77 x 1.77 inches). Insert the counter into the cutout and secure it using the provided mounting brackets.
6.2 Wiring Connections
Refer to the wiring diagrams below for proper electrical connections. Ensure all connections are secure and correct before applying power.
Figure 6.1: Side view showing the wiring diagram for the IDC-S1RH. It details connections for IN, Gate, Reset, +12V, 0V, NC, COM, NO, and Power.

Terminal Descriptions:
- IN (Terminal 1): Counting input. Connect your NPN/PNP sensor here.
- Gate (Terminal 2): Gate input for enabling/disabling counting.
- Reset (Terminal 3): External reset input.
- +12V (Terminal 4): 12V DC output (max. 50mA) for powering external sensors.
- 0V (Terminal 5): Ground for external sensor power.
- NC (Terminal 6): Normally Closed contact output.
- COM (Terminal 7): Common terminal for contact output.
- NO (Terminal 8): Normally Open contact output.
- Power (Terminals 9 & 10): AC 100-240V power input.
- SSR Output (Terminals 11 & 12): DC 12V (Max. 40mA) Solid State Relay output.
7. Operation
7.1 Power On
After proper wiring, apply power to the device. The display will illuminate, showing the current count (PV) and the set value (SV).
7.2 Adjusting Set Value (SV)
- Press the MD button briefly to enter the setting mode for the Set Value. The SV display will start flashing.
- Use the Up (
) and Down () arrow buttons to increase or decrease the flashing digit. - Press the MD button again to move to the next digit.
- Once the desired SV is set, press and hold the MD button for a few seconds to save the setting and exit the setting mode.
7.3 Resetting the Count
The counter can be reset in three ways:
- Manual Reset: Press the RST button on the front panel.
- External Reset: Apply a signal to the Reset terminal (Terminal 3).
- Power On Reset: The counter can be configured to reset automatically upon power cycling (refer to parameter settings).
7.4 Key Lock Function
To prevent accidental changes to the settings, the key lock function can be activated. Refer to the parameter settings section for instructions on enabling and disabling this feature.
8. Parameter Settings
The IDC-S1RH has several configurable parameters to adapt to different applications. Accessing and adjusting these parameters typically involves pressing and holding the MD button for an extended period (e.g., 3-5 seconds) to enter the parameter menu. Use the Up/Down arrows to navigate through parameters and adjust their values, and the MD button to confirm and move to the next parameter.
Common parameters include:
- Counting Mode: Select between UP or DOWN counting.
- Input Type: Switch between NPN and PNP sensor inputs.
- Preset Scale Factor: Adjust the multiplication factor (0.001 - 9.999) for the input pulses to display the desired unit.
- Output Mode: Configure the behavior of the relay and SSR outputs (e.g., momentary, latched).
- Reset Mode: Set whether the counter resets on power-up or only via manual/external trigger.
- Key Lock: Enable or disable the key lock function.
- Data Storage: Configure if data is stored in EEPROM or not.
For a detailed list of parameters and their specific adjustment procedures, please refer to the comprehensive manual included in the product package.
9. Maintenance
The Inkbird IDC-S1RH is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:
- Cleaning: Gently wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges. Avoid exposure to direct sunlight, excessive heat, or extreme cold.
- Connection Checks: Periodically inspect wiring connections to ensure they are secure and free from corrosion.
10. Troubleshooting
If you encounter issues with your IDC-S1RH counter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply; incorrect wiring; faulty power source. | Check power connections (Terminals 9 & 10). Verify power source voltage. Ensure wiring is correct according to the diagram. |
| Counter is not counting. | Sensor not connected; incorrect sensor type (NPN/PNP); faulty sensor; Gate input active; counting speed too high/low for sensor. | Check sensor wiring to IN (Terminal 1). Verify sensor type setting (NPN/PNP). Ensure Gate input (Terminal 2) is not preventing counting. Test sensor functionality. Adjust counting speed if possible. |
| Output does not activate. | Incorrect output wiring; set value not reached; output mode misconfigured; faulty relay/SSR. | Verify output wiring (Terminals 6, 7, 8 for contact; 11, 12 for SSR). Ensure the count reaches the set value. Check output mode parameters. Test the load connected to the output. |
| Settings cannot be changed. | Key lock function is active. | Disable the key lock function in the parameter settings. |
| Display shows erratic values. | Electrical noise/interference; loose connections. | Ensure proper grounding. Use shielded cables for sensor inputs if interference is suspected. Check all wiring connections for tightness. |
If the problem persists after attempting these solutions, please contact Inkbird customer support.
