The 2014-I typically supports three dimming modes, auto-detected or manually selected via jumpers:
| Mode | Control Signal | Wiring | |---------|------------------------|-------------------------------| | 0-10V | 0V = off, 10V = max | CTRL+ to 0-10V source, CTRL- to GND | | PWM | 5-24V PWM @ 100Hz-1kHz | CTRL+ to PWM source, CTRL- to GND | | Resistive| 0-10kΩ potentiometer | CTRL+ to pot wiper, CTRL- to pot low |
Behavior note: When control signal is disconnected, output defaults to 100% (fail-safe to full brightness).
The flexibility of the SLC 500 lies in its Input/Output (I/O) modules. These modules interface the controller with field devices (sensors, switches, motors). Aboled sc-ds-d 2014-i kontroller
The keyword aboled is a common misspelling of "obsolete" (or the German "abgelöst" - discontinued). As of 2024-2025, Aboled officially declared the SC-DS-D 2014-i as end-of-life (EOL). This means:
Why was it obsoleted? The industry shifted from analog DC servo control to digital AC servo systems with EtherCAT and PROFINET. The 2014-i, while reliable, cannot support Industry 4.0 protocols.
Since new units are abolished, the secondary market is your only hope. Check: The 2014-I typically supports three dimming modes ,
Average price (used / refurbished): $1,200 - $2,800 USD depending on condition and firmware revision.

If the SC-DS-D 2014-I is no longer available, suitable replacements must have:
Suggested equivalent series: Mean Well LDC series, Inventronics EUM series, or Aboled’s newer SC-DS-E series.
| Symptom | Likely Cause | Solution | |------------------------------|---------------------------------------|-------------------------------------------| | No output, LED off | No input power / reverse polarity | Check VIN+ / VIN- voltage (12-48V DC) | | LED flashes then off | Overload / short circuit | Reduce LED count, check wiring | | Flicker at low dim levels | Incompatible PWM frequency | Use 0-10V mode or adjust PWM to ~500Hz | | Cannot reach 0% brightness | Control signal never reaches 0V | Verify dimmer outputs <0.5V at minimum | | Output current too high/low | Wrong current setting / wrong LED load| Re-calibrate I_set trimmer |
If you are new to the AAA Diamond inspection program, please review our requirements to determine if a property qualifies to be AAA Diamond Designated.
With over 60+ million Members, 35 TourBook titles, and an audited circulation of over 8.5 million guides requested annually through Clubs, Advertising in AAA TourBooks are a unique way to ensure you’re reaching one of the most influential travel groups in North America.
AAA standards for cleanliness and condition have long been a foundation for the Diamond Program, and now the program is even stronger with the addition of ATP surface testing.
The Official Appointment (OA) is the exclusive annual logo licensing program that allows you to display your AAA Diamond and Inspected Clean designation that your property is awarded after the inspection process.
