LIVISN DC 12V 2 Channel Relay Module Self-Latching Triggering Interlocking High Low Level Trigger Load 10A DC 30V AC 250V for PLC Industrial Control Arduino
This module is widely used in the design and development of home and industrial electronic products for the majority of electronic enthusiasts. It can be used as a signal input source for single-chip computers. It is especially suitable for the electronic circuit design of students in colleges and universities. It can be docked with a single chip, or Add a level 1 drive relay or a small DC motor. The trigger end has optocoupler isolation, and the trigger power supply can be independently connected to the power supply, so that it is completely isolated;Trigger voltage: low level is 0-2.5V, high level defaults to 3.5-5V (if 12V voltage trigger, need to connect a 5.1-6.8K resistor to trigger; 24V voltage trigger, need to connect 15-22K The resistance can be triggered, otherwise it will burn out the chip) [Self-locking-SL] Self-locking is to press, the relay is closed, press again, and the relay is turned off. The self-locking type 6 channels are independent of each other, and can also be used for external contact switch (CH terminal wiring), with high level or low level trigger (optional), and can control 6 channels at the same time, such as lamp control. [Trigger--TR] Trigger (jog) is the relay pull-in when pressed, and the release button relay is turned off. It is also possible to use an external contact switch (CH terminal wiring) to trigger with a high level or low level (optional). Applicable to circuits such as electric gates, electric door locks, docking with single-chip microcomputers, etc., which only require a high or low level pulse circuit. [Interlock--IL] Interlock is a typical application fan design. When S1 presses S1, the relay pulls in; when S2 presses S1, the S2 relay pulls in. The 2-way interlock can only be turned on one way, or the external contact switch (CH terminal wiring) can be triggered with high level or low level (optional). Practical applications such as electric fan gear switch circuit.
There is a signal light on each road to clearly know which switch is working. The working mode has three options: self-locking/interlocking/triggering (jog). Adopt double-panel design PCB, 2-channel independent design, do not interfere with each other; Adopting single-chip design, the performance is stable and reliable, the anti-interference is strong, it will not be triggered by mistake, and the performance is superior; The interface design is user-friendly, equipped with terminal blocks, which can be directly connected to the leads; With 2 tact switches as product testing, directly verify the stability of the product; With power indicator (green LED) and 2 switch indicators (red LED); Use high quality relay to control the load, the load can be withstand at 250V 10A (AC) and 30V 10A (DC); Module size: 63.5x38.5x18.5mm (L * W * H), weight: 40g; Design has 4 bolt holes: spacing 58x33, aperture 3mm. Supply voltage: 12V  Quiescent current: 23mA  Working current: 110MA  Trigger: 1.CH1-CH2: Corresponding to the triggering control terminal of 1-2 relays, supporting high or low trigger triggering; 2.TRV+: The external contact power supply positive pole, if you want to contact the power supply, the jumper between RTV+ and VCC should be unplugged. 3.TRV-: The external contact power supply negative pole, if you want to contact the external power supply RTV- and GND jumper to be unplugged 4.6 micro switch: corresponding to 1-2 relay test button, valid when low level trigger; 6. High/low level trigger selection. When COM and L are connected, the low level trigger is valid. When COM and H end are connected. Package Included: 1Pcs LIVISN 12V 10A 2-Channel Self-Latching Relay Module
