Unitronics Vision350T PLC with onboard HMI

The Unitronics Vision350T PLCs with onboard HMIs have a flat fascia that makes these models suitable for the food and pharmaceutical industries. With their IP66/IP65/NEMA4X rating, these units are suitable wherever spray/wipe down applications apply.

Their PLC + HMI advantage gives users the opportunity to operate on a minimum of budget, programming time and wiring. With a wide variety of onboard and expandable I/O options, these units are capable of supporting up to 512 I/O. These configurations include digital and analog inputs and outputs, high-speed I/O, PT100/thermocouple capabilities and weight measurement. The I/O can be mounted locally or remotely, up to 1000 m from the controller.

These power-PLCs are equipped with recipe capabilities, Micro SD card memory storage for data logging and backup, and complete PLC cloning. The Vision350T units can support 24 autotuned PID loops to control temperature, level and pressure, while the 16-bit, 3.5″ 320 x 240 QVGA colour touch screen displays data, colour trend graphs and alarm screens. More than 1024 user-designed screens are possible, and up to 250 images per application. Internal memory holds 1 MB of application logic, plus 512 KB for fonts and 6 MB for images. Communication options include Ethernet, cellular and industrial protocols such as Modbus, DF1 slave, J1939 and CANopen. In addition, the Vision350T units can be ‘taught’ to communicate via almost any ASCII protocol.

The controller is also capable of time-based and immediate interrupts, making it suitable for ‘rapid response’ applications such as packaging machines.
