Sequent Microsystems The 8-RELAY card is a stackable expansion card for Raspberry Pi B+, 2, 3, 4 and Zero. It offers a compact and inexpensive solution for adding up to 64 relays to a Raspberry Pi project. Limits! This card can switch 120VAC/4A (24V if DC). If you need to switch higher voltages/currents, the 4-relay card is rated to 250VAC/10A. Please Note. The IO-Plus has 8 relays plus a lot of IO functions: 8 ADC inputs, 4 DAC outputs, 8 digital inputs, 4 digital outputs. The 8 Relay is 8 level stackable, yielding a total of 64 relays in one stack. You can also create a stack with up to 4 MegaIO and up to 4 more 8Relay cards. Two of the Raspberry Pi’s GPIO pins are used for I2C communication, leaving 24 GPIO pins available for the user. 8-RELAY adds the following I/O functions: * Eight on-board relays * Eight later stackable: add up to 64 relays to your Raspberry Pi * Command line, python drivers Technical Specifications: * Relay limits (due to PCB construction) * Relay max current/voltage: 4A/120VAC (24V if DC) * Power requirements * 10 mA @ +5V (all relays off) * 750 mA @ 5V (all relays on) Package Contents * 8 Relay board * Mounting hardware and jumpers * Relay connector plugs Resources * User Guide * Command Line & Python Drivers * Node-Red Code Example * I2C Address Map https://elecena.pl/product/22716704/8-relay-card-for-raspberry-pi-discontinued 2023-03-07 https://elecena.pl/product/22716704/8-relay-card-for-raspberry-pi-discontinued 2024-09-19
