Palm-sized PLC
8 Oct 2014
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, Unitronics says.
The HMI with 3.5” or 4.3” QVGA 16-bit touchscreen enables data entry and display of variable data, including colour 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 two 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 ideal fit for the food and pharmaceutical industries.
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.
