QF-RD21 5V/12V/24V Anti-restart Delay Switch Time Module Control Relay Module Signal Disappears Delay On/Off RelayFeatures: Voltage: 5V/12V/24V can be selected. Function: the relays are on when there is a signal, and the relays are off when the signal is lost. Output: passive output, normally open relay set + normally closed output. The maximum value should not exceed 10A. Input: voltage signal, more than 1.5V is an effective signal, and the current needs at least 0.1mA. Application: combined with travel switch and induction switch to realize: automatic closing of the door in time, interruption of the product monitoring of the assembly line, monitoring of the interruption of water flow and air flow, other purposes, etc. Specification: voltage: 5V/12V/24VZead consumption: lt; 1.0w Output: passive output, normally open relay set + normally closed output. The maximum should not exceed 10A.Life: more than 100000 actionsInput: voltage signal, more than 1.5v is an effective signal, and the current needs at least 0.1mA.Size: about 70x25x2 0mm/2.75x0.98x0.78inchScrew hole: center distance 64.5mm/2.53inch; 3.0mm/0.12 inch boreShell fitting: QF-1# shell fitting (need to be purchased separately)Time limit:First gear: range from 0.2 seconds to 30 seconds, accuracy: 0.1 secondsTwo-position: range from 0.2 seconds to 300 seconds (5 minutes), accuracy: 0.3 secondsThree gears: range from 0.2 seconds to 30 minutes, accuracy: 1.8 secondsFour gears: range from 0.2 seconds to 300 minutes (5 hours), accuracy: 18 secondsPackage included: 1x relay module timerNote: 1.
