Unipi 1.1 & 1.1 Lite

Unipi 1.1 is an extension board for Raspberry Pi. The board etends the Raspberry Pi by innputs and outputs to interac with other devices to function as a programmable logic controller (PLC) in a variety of automation applications.

• 8x Finder 36.11.9.005.4011 changeover relays (rated for 250 V~ / 10 A or 30 V⎓ / 10 A)
• 12x galvanically isolated digital inputs (0-3.5 V⎓ voltage for logical 0 and 5-24 V⎓ voltage for logical 1, 5 ms minimum pulse lenght)
• 2x 0-10 V⎓ analog inputs
• 1x 0-10 V⎓ analog output
• 1 × 1-Wire port for connection to 1-Wire thermometers and other sensors
• 1 × I²C port for expansion
• 1 × UART port for external serial communications
• socket for RTC (real-time clock) battery

Unipi 1.1 Lite is a smaller and simpler variant of the Unipi 1.1, designed for smallest automation projects. When compared to the Unipi 1.1, it features fewer I/O's but is more compact and cheaper.

• 6x Omron G5Q-14-EU changeover relays (rated for 250 V~ / 10 A or 30 V⎓ / 5 A)
• 6x galvanically isolated digital inputs (0-3.5 V⎓ voltage for logical 0 and 5-24 V⎓ voltage for logical 1, 5 ms minimum pulse lenght)
• 1 × 1-Wire port for connection to 1-Wire thermometers and other sensors
• short circuit LED indication

Unipi 1.1 use Raspberry Pi computer as their computing module. Unipi 1.1 and Unipi 1.1 Lite board are compatible with the following Raspberry Pi models:

• Raspberry Pi 2 Model B
• Raspberry Pi 3 Model B
• Raspberry Pi 3 Model B+
• Raspberry Pi 4 Model B (all RAM variants)

Raspberry Pi can be purchased either separately, or as a part of one of the practical sets available on our e-shop.

The Raspberry Pi is connected via its GPIO through a ribbon cable, processes all data from I/O modules and is sending responses. All individual I/Os and communication interfaces are connected to the Raspberry Pi's CPU either directly via GPIO or indirectly via I²C. Raspberry Pi also provides network connectivity and USB ports.

The I²C port supports connection of extension modules, such as the EMO-R8 relay extension.

The 1-Wire bus is used for passive reading of data from corresponding 1-Wire sensors (humidity sensors, temperature sensors etc.). One bus can receive data from up to 15 sensors with a maximum total length of the bus up to 200 meters (provided a suitable 1-Wire hub is used).

Note: Unipi 1.1 and 1.1 Lite require an external 5 V⎓ / 2.5 A power source with 2.1mm DC jack.
