Dual Timer Relay ON OFF up to 15min various voltages LD8
Dual Timer Relay ON OFF up to 15min
Features: 1.This module uses MCU as the main chip. 2.High timer precision. 3.MCU watchdog circuit and special reset chip. 4.Stable and reliable function.
Specification: Board size 70 mm x 20 mm x 20 H Board voltage 12V Relay Contacts 250Vac 10A 28Vdc 10A Relay contacts Changeover type with NO and NC contacts
Jumper OP1 1 sec to 360 sec OP2 1 sec to 15 min
T1 (relay turn on time)；T2 ( relay turn off time)
Once mode (Jumper OP3)
1. The module Power-on, relay de -energised, when external momentary switch is pushed, the relay is switched on, after delay T1 the relay opens 2. When the momentary switch is pushed during T1 timing cycle, the cycle restarts at beginning of T1 again.
Cycle mode(Jumper OP4)
1. The module Power-on, When triggered the relay is switched on, after delay T1 the relay de-energises for delay T2 and will continue to loop. 2. When the momentary switch is pushed during T1 or T2 timing cycles, the cycle restarts at beginning of T1 again.
3. If you want it to automatically start at power up (either mode) then short out the momentary switch input.
Many uses including pump control, decoy duck flapper, nutrient pump,
Package Include: 1 x Timer Relay ON OFF Cycle Module 12 Volt supplied with connection plugs and tails
