1 Multi Purpose: This module is a trigger delay module when the switch is instantly turned on, which can be used in home intelligent system, anti theft alarm delay, door control system, automation equipment control, PLC industrial control, electronic development, etc. 2 Selectable Time Range: There are 8 optional time ranges, the shortest is 0.1 seconds, the longest is 1 hour, the delay module has potentiometer adjustment, and the clockwise adjustment time will be longer. 3 Premium Relay Module Components: Using advanced high quality timing chip control, accurate timing, using high power relay to control the load, the maximum can reach 10A. 4 Safe to Use: Vibration sensor module has anti power reverse protection diode, which can better protect the module. The trigger terminal is isolated by optocoupler, which has strong interference ability and avoids false triggering. 5 Characteristic: Time delay controller board also has power indication and delay switch indication, and the relay output has normally open and normally closed interfaces.
