Mini 5/12/24V DC Infinite Cycle Delay Time Timer Relay Turn ON OFF Switch Module

Description

Features:
This module uses MCU as the main chip, higher timing precision.
MCU watchdog circuit and special reset chip.
Stable and reliable working performance.
Working model: once mode and cycle mode.
The delay time error of all kinds of temperature and humidity is less than 2%.
Specifications:
Once mode (Jumper OP3)
1. The module power-on, after triggered, the relay is switched on, delay T1, and the relay is disconnected.
2. At the delay process, trigger again, it will immediately interrupt the delay.
Cycle mode (Jumper OP4)
1. The module power-on, after triggered the relay is switched on, delay T1, and the relay is disconnected, delay T2, the relay is switched on again. Such cycle. T1 and T2 are set by two adjustable resistors, respectively.
2. At the delay process, again triggered, it will immediately interrupt the delay.
Jumper OP1: 1 to 100 seconds, 0.1 seconds of regulation accuracy
Jumper OP2: 1 seconds to 15 minutes, 1 seconds of regulation accuracy
The delay time error of all kinds of temperature and humidity is less than 2%
Typical application reference
Timing operating equipment, such as every trigger by pressing key, then automatic power off after 5 minutes.
Machine repeat test circuits, such as a cycle of testing: power on for 1 minutes, then power off for 1 minutes.
Fish tank pump intermittent pumping oxygen.
Other timer control equipment.
