2PCS TK1801 10A 3-Digit Red Digital Display Time Relay Module DC12V 1-999min Delay-On Delay-Off Timer Control Board

【Function and Operation Description】 Function: Start delay after triggering, the relay is immediately turned on, and the relay is turned off after the countdown ends. 1. Trigger: Refers to a brief contact between the two wires of the KEY terminal, usually with an external button or voltage signal; Note that triggering again after triggering is invalid and must wait for the countdown to end before triggering again. 2. Time adjustment: Press the Up key to increase the time up to 999, and press the Down key to decrease the time down to 1. The unit of time is seconds; Note that during the countdown, the adjustment time will immediately stop the relay and return to the initial state. Press and hold the button to quickly adjust the time. After adjusting the time, do not immediately turn off the power. You should wait for more than 1 second to ensure that the set time is effectively saved. The next time you turn on the power, it will be adjusted to the last setting. 3. Display: When not triggered, display the set time; After triggering, display the remaining time (countdown); The setting process flashes to display the set time. 【Parameters】 Voltage: 12V DC (range 10V-16V) Power consumption: 0.5W Time range: 1-999 min Display mode: 3-digit red digital display (displays the remaining time during the countdown process, otherwise displays the set time) Time adjustment: Button adjustment (with power-off memory, automatically adjust to the final setting when powered on next time Accuracy: 1 second Error: 2% Trigger method: Short circuit for 0.025 seconds or more is effective Output contacts: a set of normally open+normally closed Output capability: 10A (voltage range 0-250V AC, or 0-30V DC) Output mode: Passive (equivalent to a switch) Size: 60*40*20mm Hole diameter: 3.2mm Weight: 30g 【Interface Description】 12V+: Positive of power supply 12V -: Negative of power supply NO: Normally open terminal of relay COM: Common terminal of relay NC: Normally closed terminal of relay KEY-1: Button external terminal, input from here when triggered by voltage. With triangular markings KEY-2: Button external terminal, actually connected to 12V+ Note: "Connected" in the function description refers to the connection between the "common" and "normally open" of the relay 【Mode Setting Method】 (Be careful to be fast) Press the down arrow key multiple times immediately after power on to enter the time range setting. At this time, P00 will flash. Use the up and down arrow keys to switch. After the setting is completed, wait for 2 seconds to complete. Code range description: The following is the delayed disconnection P00: Time range is 1-999 seconds, triggering connection, delayed disconnection P01: The time range is 1-999 minutes, triggering connection and delaying disconnection P02: Time range is 1-999 hours, triggering connection, delayed disconnection P03: Time range of 0.1-99.9 seconds triggers connection, delayed disconnection The following is the delayed connection P04: The time range is 1-999 seconds. When powered on, it is disconnected. After triggering, it is disconnected and the connection is delayed P05: The time range is 1-999 minutes. When powered on, it is disconnected. After triggering, it is disconnected and the connection is delayed P06: The time range is 1-999 hours. When powered on, it is disconnected. After triggering, it is disconnected and the connection is delayed P07: The time range is 0.1-99.9 seconds. When powered on, it is disconnected. After triggering, it is disconnected with the connection is delayed Triggering is invalid during the delay process, and can be triggered again after the delay ends. Short circuit the KEY terminal when triggered, or trigger with voltage.
