So, the lack of documentation is an incredibly serious flaw. Also, it appears that one cannot use this as a delay off relay module. It will come close with F2, but the time counts down after a specific pin receives a signal, and to keep it on you would have to pulse the signal, which is really impractical. I have another delay off module from another seller that works, but only one relay, and I need at least 8. Very disappointing.

The instructions are, well, there are no instructions! No idea why retailers don’t provide, maybe it’s because it’s made in China, or they’re just too cheap to care. Who knows, it seems to me some poor ratings of like items might be due to the end user not knowing how to program and its functions. At present, the unit appears to be functioning well and seems stable. If time demonstrates a different outcome, I’ll report. But for now, here’s instructions on how it functions and parameters for programming.Walfront 8CH Delay Cycle Relay TimerConnections:VIN, GND, In1, In2, In3, In4, In5, In6, In7, In8.VIN = positive voltage inGND = negative voltage inIn1 through In8 - To trigger relay(s): connect dc-(GND) to any “In1” through “In8” connector.Each relay will trigger to its independent programming.Controls:Set, ++, --, OKSet = Short press enters Programming – repeat press will toggle through functions and parameters++ = increases Function and event duration-- = decreases function and even durationOK = single press = enter – double press = displays timer – hold 5 seconds = turns display off/onFunctions:F0, F1, F2, F3, F4, F5F0 = NO – F1 = NCF2 = NO – F3 = NCF4 = NO – F5 = NCF0 & F1 is controlled by parameters; 2 (seconds), 3 (minutes) & 4 (hours). Relays are ON for the time noted by 2, 3 & 4. Off for same duration. Parameters 5, 6 & 7 do not function for F1 or F2.F2 & F3 is controlled by parameters; 2 (seconds), 3 (minutes) & 4 (hours) -AND- parameters 5 (seconds), 6 (minutes) & 7 (hours). Parameters 2, 3, & 4 control the duration of the relay on, parameters 5, 6 & 7 control the duration of the relay off.F4 & F5 are similar to F2 & F3 but will be triggered upon powering on of the relay board.In all functions (F0 – F5) parameter 8 controls repeat cycle (8 set to 0 = continuous cycling. 8 set to 1+ controls the number of cycles. Note: each cycle of either “on” or “off” is considered one cycle. See Parameter Outline for more information.Parameters; 2 through 8:2 - duration in seconds3 - duration in minutes4 - duration in hours5 - duration in seconds6 - duration in minutes7 - duration in hours8 - repeat cycle time: 0 = continuous, 1+ = number of cycles, see cycle note.Cycle note (parameter #8):Setting to 1 will cycle the relay one time. From NO to closed back to NO.Setting to an even number will cycle the relay then rest on the opposite beginning position of the relay. If relay began as NO the relay will cycle then rest on the opposite position NC.Setting to an odd number will cycle the relay then rest on the beginning position of the relay. If the relay began on NO the relay will cycle then rest on the same position NO.
