Seeit HLE-RELAY04-5V Relay Control Card Module for Arduino, AVR, PIC, Raspberry Pi, TTL HLE-RELAY04-5V

The Seeit interface board facilitates control of multiple appliances and equipment through its relay modules. Each input of the interface is isolated by a photo coupler for added safety. It can be directly controlled by various microcontroller PCB cards such as Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, or any other TTL logic signals. The relays are configurable to be active on low or high-level signals. LEDs provide visual indication of the status of each relay.
