This listing is for a variety of Channel/Voltage relays with selectable high/low triggers.
The assorted option for each voltage contains the below:
4x1 Channel (of selected voltage)
2x2 Channel (of selected voltage)
1x4 Channel (of selected voltage)
1x8 Channel (of selected voltage)
Description:
Module description:
1, The module uses genuine high-quality relays and parts, the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A;
2, Using patch optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;
3, The module working voltage has 5V-12V-24V
4. The module can be triggered by a jumper to set a high level or a low level;
5, Fault-tolerant design, even if the control line is broken, the relay will not move;
6, Power indicator (green), Relay status indicator (red)
7, The interface design is user-friendly, all interfaces can be directly connected through the terminal block, very convenient
8, With 4 fixing bolt holes, hole 3.1mm
Module interface:
1. DC+: Connect the positive pole of the power supply (the voltage is required by the relay)
2, DC-: connected to the negative pole of the power supply
3, IN: can control the relay to pull high or low
Relay output:
1. NO: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction.
2, COM: relay common interface
3. NC: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.
High and low trigger selection:
1. When the jumper is shorted to LOW, it is triggered by low level;
2. When the jumper is shorted to high, it is triggered by a high level.
