Unitronics recently introduced the newest members of its Vision350 PLC+HMI family- flat fascia Vision350 units. With their IP66/IP65/NEMA4X rating, these units are recommended wherever spray/wipe down applications apply. With a wide variety of onboard, and expandable I/O options, these new 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 1000m from the controller. These power-PLCs are equipped with recipe capabilities, Micro SD card memory storage for data logging and back up, complete PLC cloning and more. Communication options include Ethernet, cellular, and industrial protocols such as MODBUS, DF1 slave, J1939, CANopen and more. In addition, the Vision350 units can be ‘taught’ to communicate via almost any ASCII protocol. The controller is also capable of time based and immediate interrupts, making it a natural for ‘rapid response’ applications such as packaging machines.
