Specifications:
Size:69×19×17mm (2.7×0.7×0.6")
Feature
- This module uses a single- microcomputer as the main control core with high time precision.
- Built-in watchdog circuit and dedicated reset of the MCU.
- Stable and reliable performance.
[SINGLE MODE]
1. Not operating after -on. The relay is turned on after the trigger and disconnected after the arrival time.
2. When the relay is triggered again during the delay process after the relay is turned on, it will be interrupted immediately.
[CIRCULAR MODE]
1. Not operate after -on. The relay is turned on after the trigger and disconnected when time T1 arrives. It turns on after reaching T2 time. The process will be repeated. T1 and T2 are set by two adjustable resistors.
2. During the delay process, if it is triggered again, the delay will be interrupted immediately.
[Typical Application Reference]
1. Time-limited work , such as automatic off after 5 minutes of button trigger.
2. Machine circuit repeatedly, such as on for 1 minute and then off for 1 minute.
3. Aquarium water pump intermittent pumping oxygen.
4. time control device.
[Performance]
PO1: 1s to 100s, 0.1 second of adjustment accuracy.
PO2: 1s to 15mins, 1 second of adjustment accuracy.
The delay error does not exceed 2% under various temperatures and humidity.
Package include:
1 x Relay Module
