ITEM NAME:HW-803 1 Way Relay Module w/Optocoupler Isolation High Low Trigger (12V) A#S Product Description Description: Feature: 1. The module adopts high-quality relays with normal interface and maximum load: AC 250V/10A, DC 30V/10A. 2. Using patch optocoupler isolation, strong driving ability, stable performance, trigger current 5mA. 3. The working voltage of the module is 5V. 4. Modules can be triggered by setting high or low levels through jumpers. 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 humanized. All interfaces can be directly connected through the terminal, which is very convenient. Specification: Product size: 50*25*15mm/1.96*0.98*0.59'' Packing weight: 17g Voltage: 12V(HW-803B) Module interface: 1. DC+: Connect the positive pole of the power supply (voltage according to relay requirements, 5V.12V and 24V options) 2. DC-: Connect power supply negative pole 3. IN: High or Low Level Control Relay Suction Relay output: 1. NO: Relay often opens interface. Relay is suspended before suction and short-connected with COM after suction. 2. COM: Relay Common Interface 3. NC: Normally closed interface of relay, short connection with COM before relay suction, suspension after suction High and low level trigger selector: 1. Short connection between jumper and LOW is triggered at low level. 2. Short connection between jumper and high is triggered by high level Note: Please allow 1-3mm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understand. Included: 1 X HW-803 One Channel Relay Module.Using patch optocoupler isolation, strong driving ability, stable performance, trigger current 5mA. Power indicator (green), relay status indicator (red). NO: Relay often opens interface. Relay is suspended before suction and short-connected with COM after suction.
