Samba, an all-in-one, palm-size PLC with HMI and onboard I/Os, fills a growing niche—OEMs on a tight budget who need compact controllers for simple machine control, but still want the competitive advantage of an elegant, color-touch HMI panel. The first model of Samba was released this spring; now, only few months after that launch, Unitronics is expanding the series with 4.3″ HMI panel model. The beautiful HMI with 3.5” or 4.3″ QVGA 16-bit touchscreen enables data entry and display of variable data, including color Trend graphs and alarm screens. Samba supports 24 user-designed screens, and up to 40 images per application. The integrated PLC offers a broad range of features including 2 auto-tuned PID loops, time-based RTC control, data logging, recipes and more.
The internal memory holds 0.5 MB of application logic, plus 512K for fonts and 0.5 MB for images. Onboard I/Os offer digital, analog, and high-speed functionality.
The flat fascia and IP66/IP65/NEMA4X rating makes Samba an excellent fit for the food and pharmaceutical industries—ideal wherever spray or wipe down requirements apply. Both Samba units come supplied with a programming port (USB for 4.3”, RS232 for 3.5”). Additional ports can be added: RS485 or Ethernet, and CANbus port. Samba supports GPRS/GSM, email and SMS, as well as industrial TCP/IP protocols, MODBUS, DF1 slave, CANopen, and J1939; it can also be adapted to any 3rd-party protocol.
Samba™ uses Unitronics’ free VisiLogic software. Visilogic provides a single, simple environment for hardware and communications configuration, Ladder application development, and HMI design, including a free library of industrial images. Free utilities include remote PC access and data export. Unitronics offers free technical support for all of their products and supports an active user forum.
Samba offers all the functionality system integrators need for small applications, reduces space and wiring requirements, and eliminates the need to set up Panel-PLC communication—resulting in an excellent price-performance ratio.
Unitronics (R”G) Ltd. is an Israeli company with international presence that has been producing PLCs, automation software and accessory devices since 1989.
The very first all-in-one controller—HMI+ PLC + onboard I/Os—was released by Unitronics nearly 25 years ago. An early pioneer of this market, Unitronics continues to be a global trendsetter in developing and manufacturing all-in-one controllers with a price/performance profile that boosts competitive advantage.
Unitronics’ OPLC controllers combine full-function PLCs and HMI operating panels into single, compact units. These HMI + PLC devices are programmed in a single, user-friendly environment. Our clients save I/O points, wiring, space, and programming time; elements that translate directly into cost-efficiency.
Unitronics supports a global network of distributors, as well as a US subsidiary.
