Sequent Microsystems has introduced the Raspberry Pi “4-relay” add-on to the Industrial IoT<\/a><\/strong> market. Four relays switch lines for loads up to 10 A and 250 V, can be stacked up to 8 times with max. 32 switched relays.<\/p>\n\n\n\n

It can be used to control loads of up to 10A and 250V. You can control directly all your lights and appliances. Pluggable connectors accept 18 to 22 AWG wires and simplify the installation, specially if you are planning to use more than one card. The cards are stacked with 18mm male-female standoffs. All the hardware required for the installation is provided. Relays are controlled through I2C IO Expanders, using only 2 pins on the GPIO interface and leaving all the other pins available for the user.<\/p>Source: https:\/\/www.kickstarter.com\/projects\/279405789\/4-relays-for-raspberry-pi-8-level-stackable-10a-250v-each\/<\/a><\/cite><\/blockquote>\n\n\n\n

Some industrial IoT devices<\/a><\/strong>, based on Raspberry Pi platform already offer Relay expansion modules. One of them is ModBerry 500 CM4<\/a><\/strong> series, introduced in 2014 – later upgraded with latest Raspberry Pi’s Compute Module 4+<\/a><\/strong>. ModBerry standard configurator offers up to 12x Relay expansion, with additional customizable options available for larger orders.<\/p>\n\n\n\n

ExCard modules to peak the performance<\/strong><\/h3>\n\n\n

Every TECHBASE\u2019s industrial computer is supported by ExCard add-on modules for extra RS-232\/485 serial ports, Ethernet ports, PCIe slots, analog input and output, digital I\/Os, relays, M-Bus interface, opto-isolation, accelerometer, etc. To provide specific communication paths, ModBerry can be rigged with additional Wi-Fi\/Bluetooth module, 3G\/LTE, NarrowBand-IoT, LoRa, ZigBee, GPS and Wireless M-Bus.<\/span>\"\"<\/a><\/p>\n
