## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE05352:1` (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/CE05352:1.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

This single-channel solid state relay module provides you access to all the pins of a solid-state relay via Screw terminal blocks onboard. This particular relay likes to be controlled using a 3-5VDC source and uses low level triggering. This means that if a voltage of 0-2VDC is detected on the DC+/- pins onboard the relay will be in a triggered state.

**Note: Switches AC loads only.**

This module specifcally used an Omron 5V solid state relay 240VAC/2A, output with resistance fuse 240ACV/2A.

The entire module is 55mm x 33mm x 25mm (length \* width \* height).

Input power: 3.3-5VDC

Input control signal voltage:

- (0-2.5V state low level relay ON)
- (3-5V state high level relay OFF)
 
Input section:

- DC+: Connect the positive pole of the power supply (powered by the relay voltage)
- DC-: connected to the negative pole of the power supply
- CH1: Relay module signal trigger terminal (low level trigger is valid)
