The RPi relay board (B) is an expansion board with 8-channel relays for Raspberry Pi. It gives your Pi the ability to control high voltage products such as household appliances. Features & Benefits - compatible with all popular Raspberry Pi models - high-quality relays, loads up to 5 A / 250 V AC or 5 A / 30 V DC - Photocoupling isolation, prevents interference from high voltage circuitry - Standard rail mounting Lower housing - Onboard LEDs to indicate relay status - Jumper for relay control pin selection, allows the relay to be controlled by user-defined pins that differ from the standard pins. - reserved control interface, allows working with controllers such as PLCs - contains development resources, including examples in wiringPi, bcm2835, python, python, python-bottle, and crontab. specifications - Supply voltage: 5 V - Trigger signal: 3.3 / 5 V - Relay channels: 8-channel - Contact form: SPDT-NO,NC - Quiescent current: 6 mA (per channel) - Connection: screw terminal strip - Dimensions: 232 × 72 mm - Mounting hole size: 3.0 mm Scope of delivery - 1x relay board - 1xrail mounting lower housing - 1x screw package Delivery without Raspberry Pi Hint: Further information can be found at: https://www.waveshare.com/wiki/RPiRelayBoard(B) https://elecena.pl/product/18565319/raspberry-pi-relay-module-8-channel-din-rail-hls8l-dc5v-s-c 2021-05-24 https://elecena.pl/product/18565319/raspberry-pi-relay-module-8-channel-din-rail-hls8l-dc5v-s-c 2022-12-04 https://elecena.pl/product/18565319/raspberry-pi-relay-module-8-channel-din-rail-hls8l-dc5v-s-c 2024-07-20 https://elecena.pl/product/18565319/raspberry-pi-relay-module-8-channel-din-rail-hls8l-dc5v-s-c 2025-02-08
