Description
2-Second to 1000-Hour Timer Board
Adjustable timer board. The listing states that timing can be set from 2 seconds to 1000 hours using an external resistor RT and the P1/P2 configuration links.
Timing adjustment
According to the listing, leave P1 and P2 open for the base timing range. Shorting P1 multiplies the timing by 8; shorting P2 multiplies it by 64; shorting both multiplies it by 512. Set the external resistor RT according to the table and consult the documentation before wiring.
Output and ratings stated in the listing
- Operating voltage: 2–5V
- Dimensions: 12 × 12mm
- After the timing interval, the output is described as going low and connecting to GND (0V)
- Maximum output sink current stated: 30mA
The listing says the output may connect to a microcontroller, transistor or a low-current load with a current-limiting resistor. Confirm the board’s actual output stage and ratings before connecting a load. Do not exceed the stated current or apply a voltage outside the listed range.
