The module uses genuine quality relay normally open interface maximum load: AC 250V / 10A, DC 30V / 10A; 2. Using SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA; 3. The module voltage is 5V, 12V, 24V available; 4. The module can be set to high or low to be triggered by jumpers; 5. Fault-tolerant design, even if the control line is destroyed, the relay will not operate; 6. Power indicator (green), relay status indicator (red) 7. The interface design is humanized, all interfaces can be directly connected to the wires through the terminal blocks, which is very convenient 8. Module size: 50 * 26 mm * 18.5 mm (L * W * H) 9. There are four fixing bolt holes, the hole is 3.1 mm, and the spacing is 44.5 mm * 20.5 mm Module interfaces: 1. DC +: positive power supply (the voltage required by the relay, there are 5V/9V/12V/24V options) 2. DC-: Negative power connection 3.IN: High or low level control relay Relay output: 1.NO: Relay normally open interface, the vacant relay before and after the pull is short-circuited to COM 2. COM: general interface relay 3. NC: Normally closed relay interface. The front of the relay is short-connected to COM, and then it is empty. End of high and low level trigger selection: 1. When the low jumper is short-circuited, the low leverage is triggered; 2. When the high jumper is short-circuited, the high leverage is triggered HW-279A / HW-279B Module description: 1. The module adopts genuine high-quality relays, and the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A; 2. Adopt SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA; 3. The working voltage of the module is 5V, 9, 12V, 24V to choose from; 4. The module can be triggered by a jumper to set high or low level; 5. Fault-tolerant design, even if the contro ProductSiteLaunchDate : 2024-09-10T09:51:25.729Z Size : One Size UnitCount : 1 UnspscCode : 39122300
