Electrobes HT88 Timer Module
закінченоview
The HT88 is a versatile timer module with adjustable timing via DIP switches, flexible trigger inputs, and controlled output behavior. A built-in test button and diagnostic LED indicators simplify installation and maintenance.
Технічні характеристики
| Пункт | Специфікація |
|---|---|
| Timer Duration Range | 1s to 10hr (selectable via DIP switches; see time settings) |
| Джерело живлення | 10V–14V AC or DC at 70mA |
| Введення | Volt-free closing or opening contact |
| Тип виводу | Identical to input voltage |
| Максимальне вихідне навантаження | 1A maximum current load |
| Перевірка функції кнопки | Forces output ON immediately, overriding TRIG input and DIP switch settings |
| Поведінка світлодіода | Power up: flashes 3 times (1 second). Output ON: constant ON. Pending: TRIG active but output off → flashes at ½ second intervals |
Quick Setup & Use
- Set the DIP switches to select the desired timer duration.
- Select the trigger contacts configuration using the DIP switch input type: Normally Open (close TRIG contacts to activate) or Normally Closed (open TRIG contacts to activate).
- Connect power using 10V–14V AC or DC (70mA) and wire the TRIG input using a volt-free contact (closing or opening depending on the selected input type).
- Connect the output load; the output is identical to the input voltage with a maximum load current of 1A.
- Optionally press the onboard test button to force the output ON immediately (overrides TRIG input and DIP settings).
- Use the LED to verify status: constant ON when output is active, and ½ second interval flashing when TRIG is active but output remains off.

Operation & Diagnostics
Перевірка роботи кнопкиPressing the onboard test button forces the output to the ON state immediately, overriding the TRIG input state and DIP switch settings.
Світлодіодний індикатор стану
- Потужність: The LED flashes 3 times (duration of 1 second) when power is first applied to the HT88.
- Вихід активний: When the output is ON, the LED remains constantly ON.
- Pending State: If the TRIG input is active but the output remains off (for example, while in delayed output mode), the LED will flash at ½ second intervals.
Усунення несправностей
- Check LED at power-up: The LED should flash 3 times (duration of 1 second) when power is first applied.
- Output not turning ON when TRIG is active: If the TRIG input is active but the output remains off (e.g., in delayed output mode), the LED will flash at ½ second intervals—confirm the selected operating behavior and timing.
- Verify DIP switch and TRIG behavior: Ensure the selected input type matches your wiring: Normally Open requires closing TRIG contacts to activate; Normally Closed requires opening TRIG contacts to activate.
- Use the test button to isolate faults: Pressing the test button should force the output ON immediately; if it does not, re-check power and output wiring.
