The Samba PLC & HMI for Small Machines from Unitronics is an all-in-one Programmable Logic Controller with an integrated touchscreen. Measuring 3.5, 4.3, or 7-inches it offers onboard I/O with six possible configurations. The Samba offers features to compete with high-end PLCs. It has a range of supported communication protocols, data logging and Trend capabilities, plus a built-in alarm management system. However it is priced closer to a push-button or smart relay system. Unitronics programming software and technical support is complimentary to all users, giving the Samba All-in-One PLC+HMI as significant price to performance ratio.
