Single relay module (5V, 12V)

Overview

product description

This 1-way relay module can be used in situations with large interference. It can be powered by two completely isolated power systems, ensuring that the relay will not affect the signal loop when switching. At the same time, it can also be freely switched to high-level drive mode. Or low level drive mode. The use of Songle's high-quality relays ensures that the module has a long service life.

Features

Complete photoelectric isolation, dual power supply.
High-level drive mode or low-level drive mode can be switched at any time.
Songle original high quality relay.
