## Description

Control up to 4 independent loads with the Raspberry Pi's GPIO pins. The relay hat uses GPIO pins 26, 19, 13, and 6 to control four relays. Each relay has 3 pins broken out: normally closed (NC), normally open (NO), and common (C) which are terminated with screw terminals. Each of the four channels has an on-board LED to show the current state of each relay. The LEDs are setup as a normally open connection, this can be changed to a normally closed connection by changing the jumpers on the bottom of the board. All four channels of the relay board are designed to isolate and protect the Raspberry Pi from the load switched by the relay. Each channel is optically isolated using the 16 pin quad opto-isolator (or optocoupler) which electrically separates the output signals (GPIO) from the relay drive circuits and the relay separates the load from the switching signal for another layer of protection. The relays also have flyback diodes in place to protect the drive circuit from inductive spikes from the relay coils. Official "Raspberry Pi HAT" relay board. The 4 channel relay hat uses an on-board EEPROM as specified by the Raspberry Pi foundation to tell the Pi which GPIO pins are being used and the protocol they are using.
