Cryfokt Delay Timer Module with Optocoupler Isolation 0.2 S-100 S for DIY Electronic Projects.

1. A short voltage pulse is applied to the actuator terminal; the module starts immediately (relay activated) and the relay turns off after a certain time. The input signal is invalid again during the delay.

2. The optocoupler completely isolates the input current from 1 mA, and the module can drive voltages above 2.0 V. It can maintain a voltage above 20 V for extended periods. 3. It offers a set of normally open and normally closed output configurations. 4. The adjustable delay time is from 0.2 seconds to 100 seconds. Other time ranges can be set. 5. Four speed delay ranges are available, with optocoupler isolation for high safety.

Specification: Item Type: Time Delay Relay Module. Operating Voltage: 12 V DC, adaptable range (10 V-16 V).

Operating current: 50 mA (5 mA static) Switching capacity: 10 A (0~ AC or 0~30 V DC) Output shape: a set of normally closed + normally closed (i.e., dry) Input: The optocoupler completely isolates the input current to 1 mA, and the voltage above 2.0 V can be driven. Do not maintain the voltage above 20 V for extended periods. Signal voltage range: 3-30 V DC. Response time: 20 ms. Delay length: adjustable from 0.2 seconds to 100 seconds. (Other time ranges can be defined) Delay setting method: short-circuited, short-circuited indicates a range of 1 to 10 s; short-circuited, not short-circuited indicates a range of 1 to 100 s; no short-circuit, short-circuited to indicate a range of 1 to 1000 s; short-circuited, short-circuited indicates a range of 1 to 10,000 s. Adjust potentiometer R4 at this time to set the time. Package list: 1 x time delay relay module
