Product Description
Delay Mainboard Size: 8.2CM * 3.2CM (length and width)
Delay circuit board motherboard projecting element size: 11CM * 3.2CM
Dashboard backup battery Dimensions: CM * CM
Delay control board voltage: 5-12V;
Standby power supply control voltage: 5-12V;
Charged voltage: 250V AC 10A or 30V DC 10A
Features:
Relay delay reset after a power failure, power failure before the relay does not operate, immediately after the power relay action, and so the delay time after a relay reset after power reset.
1, the standby power control panel for use:
This module is power-off delay module, the system needs a backup power source, the battery power supply can also use other power supply line, the current need to be able to drive a relay (300MA power and above), the voltage 5-12V can. If the backup power supply voltage of 5 to 7V, the shorting cap POWER_C standby power control board plug, if it is 7 to 12V, the shorting cap on POWR_C can be removed.
1, the control signals (5-12V, current 300MA above)
5 to 12V control signals can be directly.
When the control signal 5-7V, POWER_C shorting cap plug;
When the control signal 7V-12V, POWER_C shorting cap removed;
Adjust the potentiometer counterclockwise to decrease the delay time;
Adjust the potentiometer clockwise to increase the delay time;
In order to adjust the delay time is more convenient, the circuit through an improved again, increasing the time to choose a short-circuit cap (TIME_C) than the old version
Delay 5 seconds Remove the shorting cap (TIME_C), 5 seconds to 5 minutes of delay to put TIME_C shorting cap.
Continuously adjustable delay time between 0-5 minutes, if the delay time you need more time, can close the 470UF capacitance 10UF a big change, specifically how much change can be calculated according to T = 1.1RC, R to be transfer resistance, the maximum 500K, such as the maximum delay time into 1000UF after T = 1.1 * 500000 * 0.001; T = 550 seconds.
