2-Channel Relay

The 2-Channel Relay is a board I/O module in the LabWired part catalog. Its catalog type is relay-2ch. It connects to the MCU over GPIO. The catalog gives a supply range of 4.5–5.5 V. It has 10 pins. This part is its pins. There is no separate device model because the MCU’s own GPIO/PWM/ADC model already is the simulation.

From the catalog: ProtoSupplies 5V × 2 opto module (51 × 39 × 20 mm), JD-VCC jumper assumed fitted: logic LOW on IN1 or IN2 energizes that coil. boardIoChannels keeps the two inputs independent; boardIoActiveHigh is false. COM/NO/NC per channel are passive load pads. The contacts are not a switched device model.

How to simulate the 2-Channel Relay in LabWired

1. Open the Playground at app.labwired.com and place an MCU board.
2. Add the 2-Channel Relay (catalog type relay-2ch).
3. Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 4.5–5.5 V.
4. Connect IN1 and IN2 to free GPIO pins.
5. Connect COM1, NO1, NC1, COM2, NO2 and NC2 as your circuit needs.
6. Run the firmware. It reads and drives these pins through the GPIO, PWM and ADC models of the MCU. The part has no separate device model.
