Raspberry Pi IO card for Building Automation

Bringing a powerful Industrial Interface to the Raspberry Pi world, this card packs an amazing set of features into a small 85x58mm form factor.

• Eight universal inputs selectable to read temperatures from 1K or 10K thermistors, 0-10V analog inputs or dry contact counters.
• Four 0-10V analog outputs can be used to control dimmers or other industrial devices.
• Four triac outputs can switch AC loads of up to 0.5A and 500V.
• Status LEDs show the state of all digital inputs and outputs
• Four general purpose LEDs can be programmed to indicate error conditions, excess temperatures or combinations of inputs and outputs.
• RS485/MODBUS communication port.
• Real Time Clock with battery backup.
• On-board hardware watchdog will power cycle Raspberry in case of software lock-up
• On-board resettable fuse
• Common 24VAC power supply using a standard transformer will also power the Raspberry Pi
• Heavy Duty pluggable connectors
• High quality brass mounting hardware included

A complex data acquisition and control system can be built by stacking up to eight MEGA-IND cards on top of one Raspberry Pi

Software

All the features of the MegaO-IND card are accessible from a command line interface which can be downloaded from GitHub. Python drivers are available as well. Node-Red source code examples are available to access all the card's resources.
