TK1305A 12V DC Multifunctional Time Delay Relay Module with Optocoupler Isolation

Features: ? Function 1: Trigger once (relay), then trigger once disconnect (disconnector), each time the relay is triggered once, the module has self-locking function. Function 2: Turn on immediately after triggering, and disconnect after the delay time arrives. Function 3: Disconnect immediately after triggering, and turn on after the delay time has elapsed. (Note: the relay will not be turned on for the first time) ? Specifications: ? Power supply: DC 12V &pm; 1.5V Trigger mode: The optocoupler is isolated and triggered. When the input signal voltage is maintained for more than 20 milliseconds, the trigger will be executed. In order to improve the anti-interference ability, signals below 20 milliseconds are filtered out. Trigger signal requirements: current > 0.5mA, voltage 1.7V ~ 18V, level time > 20mS Quiescent current: <10mA Pull-in current: 45mA @12V Load capacity: AC 10A 250V or DC 10A 30V Delay error: &pm;2% Can be set from 0 seconds to 1 hour, 32 time values can be set. ? Package Included: ? 1 x TK1305A 12V DC Multifunctional Time Delay Relay Module
