The 8-Channel Relay Board is an expansion board with relays which has been designed specifically for the Raspberry Pi. It gives your Pi the ability to control lots of high-voltage components (such as home appliances) to create a full home automation system. The relays are rated at 5A 250V AC or 5A 30V DC (Max) and feature photo-coupling isolation to reduce interference. Onboard LEDs indicate each relay's status for visual indication and debugging support. The board comes in a frame ready to fit into DIN rails if desired. Features * Standard Raspberry Pi 40-pin GPIO extension header * High-quality relays - loads up to 5A 250V AC or 5A 30V DC * Photo coupling isolation, prevent interference from high voltage circuit * Standard rail mount bottom case * Onboard LEDs for indicating relays status * Relay control pin selection jumper - allows the user to control the relays by custom pins other than the default pins * Reserved control interface allows the board to work with controllers like PLC * Comes with development resources and guide Resources * Product Wiki and guide Tech Specs * Power supply voltage: 5V * Trigger signal: 3.3V/5V * Relay channels: 8 * Contact form: SPDT-NO,NC * Closed current: 6mA (per channel) * Connector: screw terminal block * Dimension: 232 × 72 (mm) * Mounting hole size: 3.0mm https://elecena.pl/product/22719249/8-channel-relay-expansion-board-for-raspberry-pi 2023-03-07 https://elecena.pl/product/22719249/8-channel-relay-expansion-board-for-raspberry-pi 2023-12-27 https://elecena.pl/product/22719249/8-channel-relay-expansion-board-for-raspberry-pi 2024-09-19 https://elecena.pl/product/22719249/8-channel-relay-expansion-board-for-raspberry-pi 2024-11-29 https://elecena.pl/product/22719249/8-channel-relay-expansion-board-for-raspberry-pi 2024-11-30 https://elecena.pl/product/22719249/8-channel-relay-expansion-board-for-raspberry-pi 2025-08-05 https://elecena.pl/product/22719249/8-channel-relay-expansion-board-for-raspberry-pi 2025-11-28 https://elecena.pl/product/22719249/8-channel-relay-expansion-board-for-raspberry-pi 2025-11-29
