**Type:** Product page · **SKU:** CE05137 · **Brand:** [Core Electronics](https://core-electronics.com.au/brands/core-electronics-australia)
**Page:** https://core-electronics.com.au/5v-single-channel-relay-module-10a.html ([markdown](https://core-electronics.com.au/5v-single-channel-relay-module-10a.html.md))

A versatile, compact relay board that can drive up to 10A @28VDC while only drawing approximately 60mA at 5V.

## Pricing

- **Price:** $3.95 (inc GST) — $3.59 AUD, exc GST
- **Quantity discounts:** 5+ $3.52 (exc GST) · 15+ $3.41 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 130 today, and up to 300 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE05137:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE05137:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

A versatile little relay board. This relay channel can drive up to 10A @28VDC

- While marked as a 5V supply voltage & input signals, we've found these relays to consistently work at 3.3V. If your unit isn't triggering, have a look at the notes to the right.
- Equipped with a high-current 10Amp relay
- 2x LEDs that show the current state of the relay
- Some markings are in Chinese; the key input connectors are in English

### Specifications

- 10 A Relay
- Active Low (Pull to GND)
 
The relay is active when the control signal is pulled low. If control is left to float or at Vcc voltage, the relay is inactive.

**Notes:** It should be noted that the supply pin (Vcc) voltage needs to be the same as the logic level voltage (IN) pin for this relay to work. For example, you would need to use the 3.3V rail on a Raspberry Pi as its GPIO pins operate at 3.3V.

### Examples

#### Raspberry Pi Pico - Micropython

 ```
from machine import Pin
import time

# Define the trigger and echo pins
relay = Pin(1, Pin.OUT)

# Turn the relay on and off forever
while True:
    relay.toggle()
    time.sleep(1)
```
