Relay Module is available now from our US and UK warehouse Free shipping to US and UK in 3-6 business days ship to Canada, Brazil in 7-10 days in US warehouse ship to European countries in 7-10 days in UK warehouse 5V/12V/24V FRM01 Multifunctional Relay Module Loop Delay Timer Switch Self-Locking Description: Users can display the buttons and select the following nine kinds of functions in one, you can set and save 9 kinds of function parameters, you can also view the current function parameters, time parameter sets the minimum one second adjustable accuracy of better than 0.1 seconds. Feature: Function 1: Timing Pick: After power relay delay time T1, T1 in 0 seconds adjustable between -270 hours, give CH1 connector is a high pulse signal(high duration is greater than or equal 20ms, hereinafter the same) repeat the above functions Function 2: Timed disconnect: On power relay, time relay off delay time T1, T1 in 0 seconds adjustable between -270 hours, giving a high level pulse signal CH1 connector, repeat the above functions Function 3: Loop Timing Mode 1: After power on, to not pull the relay, the delay time T1 after arrival relay; pull the relay off time T2 after arrival, and then repeat the above state, the delay time T1 and T2 in 0 seconds adjustable between -270 hours, giving a high level pulse signal CH1 connector, you can resume these functions Function 4: Loop Timing Mode 2: After power, the relay immediately pull, delay time T1 after arrival relay off; off time T2 arrives relay, and then repeat the above state, the delay time T1 and T2 in 0 seconds - adjustable between 270 hours and give CH1 connector is a high pulse signal, these functions can be re-started Function 5: Latching relay mode: CH1 connector to relay a high level pulse signal, the relay, to give a high level pulse signal relay disconnected Function 6: Trigger relay mode: CH1 connector to a high signal relay, relay, high disappeared, relay disconnected Function 7: Finite loop timing mode 1: Function 3, based on the number of cycles increased functionality, then T1 and T2 in 0 seconds -9999 seconds adjustable between 1-9999 times in between cycles adjustable Function 8: Finite loop timing mode 2: In function 4, based on the number of cycles increased functionality, then T1 and T2 in 0 seconds -9999 seconds adjustable between 1-9999 times in between cycles adjustable Function 9: Customized Mode: Reserved Two module interface: Module control side: there are 3-wire interface, all interfaces are terminal, user-friendly DC+: DC power supply positive(with 5V, 12V and 24V modules to choose from) DC-: DC power cathode CH1: Hold Input Detection Interface Relay outputs: A 3-wire interface, all interfaces are terminals NO1: normally open relay interface, the relay becomes vacant before, pull shorting after the COM1 COM1: Relay Common Interface NC1: normally closed relay interface relay shorted before and COM1, pull vacant post Module: 5V / 12V / 24V (please choose one you need) Package included: 1 x Multifunctional relay module (5V / 12V / 24V please choose one you need)
