Product parameters: Voltage: 6V~30V(support micro USB 5.0V) Output Capacity: can control no more than DC 30V 5A AC or 220V 5A Quiescent Current: 20mA Operating Current: 50mA Operating Temperature: -40℃~85℃ Timing Range: 0.1seconds to 999 minutes(continuously adjustable) Trigger Signal Source: High voltage level trigger(3.0V~24V), signal ground and system ground are not connected to improve system anti-interference ability(or you can connect them). Optocoupler Isolation: improve the anti-interference ability, after the parameter setting, it will memory forever . Warning: Relay contact is passive and electricity production; 1 channel has the control function on / off. Operation Mode: P1: After triggering signal, switch is connected for "OP" time, then disconnected; within the "OP" time: P1.1: if trigger signal again, it is invalid. P1.2: if trigger signal again, restart timing. P1.3: if trigger signal again, switch is disconnected, stop timing. P-2: After triggering signal, switch is disconnected for "CL" time, then switch is connected for "OP" time, and disconnect after timing. P3.1: After triggering signal, switch is connected for "OP" time, then switch is disconnected for "CL" time, and enter loop. If trigger signal during loop, switch is disconnected and stop timing. The loop times (LOP) can be set. P3.2: After power on, no need trigger signal, switch will be connected for "OP" time, then disconnected for "CL" time, and enter loop. The loop times (LOP) can be set P-4: Signal holding function. If there is trigger signal, timing will be reset, switch remains connected; when the signal disappears, it will disconnect after "OP" time. During timing, if there is a signal, timing will be reset. OP: Connect time. CL: Disconnect time. LOP: Loop times(1~999, "---" indicates infinite times). C-L Sleep mode: within 5 minutes, no operation; ni
Programmable delay modes to control the relay timings, widely used at smart home, industrial control, automatic irrigation, indoor ventilation, protection equipment etc.
Operating voltage DC 6V - 30V, support micro USB 5V power supply. High level trigger 3V - 24V. NO(Normally open) maximum load < AC 250V/10A, < DC 30V/10A. Timing range 0.1s ~ 999mins (continuously adjustable).
Built-in a diode to provide protection against accidental reverse polarity for the circuits.
If no operation within 5 minutes, the digital tube of the relay board will turn off automatically. Pressing any button can wake it up.
OP(conduction time) / CL(off time) / LOP(circuit times) can be set individually, and the parameters are mutually independent. All parameters are permanently saved once set. The functions and parameters can be reviewed or changed at a later time.
We used these to control a small motor for the turner inside a homemade egg incubator. They work as intended and they are easy enough to program once you read through the directions. I'm sure they have tons of other uses too, but they worked perfectly for our intended use and they were cheap!
