Unit SSR

SKU:U122

Description

Unit SSR is a zero-crossing solid-state relay for switching AC loads. It uses a MOC3043M optocoupler for isolation and accepts a DC 3.3 ~ 5V control signal through its Grove port. It is designed for switching single-phase AC 220 ~ 250V lighting and heating loads.

/#>1. Be cautious when using high-voltage AC loads; do not operate with power on.
2. This relay is only suitable for AC loads.

Usage

When enabled, the relay turns on near an AC voltage zero crossing. Once the control signal is removed, it turns off when the load current falls below the TRIAC holding current. Switching delay depends on the AC phase and load characteristics.
