Arduino A000110 Arduino® Shield 4 Relays Expansion module Compatible with (development kits): Arduino

The Arduino® 4 Relay Shield is a solution for controlling high-performance loads that cannot be controlled by Arduino digital I/O due to the controller's current and voltage limits. The Shield has four relays. Each relay has two pole changeover contacts (NO and NC). In order to increase the current limitation of each output, the 2 changeover contacts have been connected in parallel. Four LEDs indicate the on/off status of each relay.
