Features High Precision Performance – Experience reliable and accurate timing with our advanced timer relay module, ensuring your devices operate as intended every time Dual Operating Modes – Easily switch between mon mode (once) and cycle mode, allowing you to customize your timing needs with a simple jumper adjustment Extensive Time Range – Set both on and off durations from 0 to 60 minutes, providing you with flexible control for various applications and projects Ideal for Equipment Testing – Perfect for controlling reciprocating strokes or performing repetitive power on/off cycles, especially useful for burn-in testing of products Versatile Application – Widely compatible with timer-operated equipment, machine repetitive test circuits, and intermittent pumps for fish tanks, enhancing functionality across multiple uses Features: 1、It is a timer relay module with high precision, stable and reliable performance 2、Support 2 modes, mon mode(once) and cycle mode, and you can simply switch mode by adjusting the jumper 3、There is a wide time range that you can set, both on time and off time are adjustable 4、It is great to control the reciprocating stroke, or repetitive power on and off for equipment and products burn-in test 5、Widely used on timer operating equipment, machine repetitive test circuit, fish tank intermittent pump, etc Specification: Features: It is a timer relay module with high precision, stable and reliable performance. Support 2 modes, mon mode(once) and cycle mode, and you can simply switch mode by adjusting the jumper. There are many voltage and time range for your choice, both "on" time and "off" time are adjustable. It is great to control the reciprocating stroke, or repetitive power on and off for equipment and products burn-in test. Widely used on timer operating equipment, machine repetitive test circuit, fish tank intermittent pump, etc. Specification: Max. Load Capacity: 10A250VAC, 10A30VDC Size: 70*20mm / 2.75*0.78" Time Error: between2% T1(the relay turn on delay time),T2(the relay turn off delay time) Once Mode(Jumper OP3): 1. The module Power-on, When triggered the relay is switched on, delay T1, and the relay disconnected. 2. When triggered on the delay process, again triggered, it will immediately interrupt the delay. Cycle Mode(Jumper OP4): 1. The module Power-on, When 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. When triggered on the delay process, again triggered, it will immediately interrupt the delay.
