2 Channel Relay Module with Optocoupler, DC Relay Module Relay Relay Module Expansion Board High and Low Trigger with LED Warning Lamp for Special Sensor Shield (5V) 5V
2 Channel Relay Module with Optocoupler, DC Relay Module Relay Relay Module Expansion Board High and Low Trigger With LED Warning Lamp for Special Sensor Shield (5V)
Specification: Feature: The module uses high quality Relay with normal interface and maximum load: AC 250V/10A, DC 30V/10A. By using SMT optocoupler isolation, it has strong driving ability and stable performance; trigger current is 5mA; Modules can be triggered by setting high or low levels via wire jumpers. Fault-tolerant design, even if the control line is interrupted, the relay will not move. The interface design is humanized. All interfaces can be connected directly through the terminal, which is very convenient. Equipped with 4 fixed screw holes, easy to install. Specification: Operating voltage: 5V, 12V, 24V (optional) Maximum load: AC 250V/10A; DC 30V/10A Channel: 2 Product dimensions: 504118.5mm / 21.60.7in Power indicator: Green Relay indicator: Red Board color: Red Scope of delivery: 1 relay module Note: Module interface: 1. DC+: Connect the positive pole of the power supply 2. DC-: Connect power supply negative pole 3. IN1:1 signal trigger terminal, can set high or low control relay suction 4. IN2:2 signal trigger terminal, can set high or low control relay suction Relay output: 1. NO1: 1 channel relay normally opens the interface. The relay is hung before priming and shorted to COM1 after priming. 2. COM1: 1 channel relay common interface 3. NC1: 1 channel relay normally closed interface, short connection with COM1 before relay suction, break after suction 4. NO2: 2 channel relay often opens the interface . The relay hangs before priming and shorts to COM2 after priming. 5. COM2: Common interface for 2-channel relay
Product Features
- Safe and practical The 2-channel relay module is with transistors, diodes and optocouplers to switch higher loads safely, reliably and with little power. The module is also equipped with generously dimensioned relays in order to be able to reliably carry out many switching processes.
- High qualityThis 5V 2-channel relay module with optocouplers is perfect for controlling up to 2 devices with larger current. Equipped with 4 fixed screw holes, easy to install. Equipped with heavy-duty relays (switching capacity AC: max. 250V / 10A ; DC: max. 30V / 10A DC)
- Fault-tolerant design Even if the control line is interrupted, the relay is not moved. The interface design is humanized. All interfaces can be connected directly through the terminal, which is very convenient
- Indicator lamp power indicator (green), relay status indicator (red) The interface design is user-friendly, all interfaces can be directly connected through the terminal block, very convenient
- Wide application 5V 2-channel relay module can be directly controlled with a microcontroller Raspberry Pi, , 8051, AVR, PIC, , ARM, ARM, MSP430, TTL logic, etc
