ISOFACE™ digital output Evaluation Board EVAL_ISO2H823V2.5_B user guide EVAL_ISO2H823V2.5_B Rev 2.0 Introduction Introduction The EVAL_ISO2H823V2.5_B establishes a new standard in diagnostics for digital outputs inside industrial control applications. For example, in industrial plants with capital-intensive single-tool equipment at work or with time critical chemical processes running, obtaining in real-time differentiated feedback from the factory floor enables both preventive maintenance and drastic reduction of the time to fix a problem.
Page 6: Board Description And Specifications
ISOFACE™ digital output Evaluation Board EVAL_ISO2H823V2.5_B user guide EVAL_ISO2H823V2.5_B Rev 2.0 Board description and specifications Board description and specifications The ISO2H823V2.5 IC on this evaluation board is a digital output IC that provides eight output channels for a nominal load current of 0.5 A at 24 V. The output channels are suited for resistive, inductive, and capacitive loads with the limits described in the datasheet.
Page 7: Board Functionality
To demonstrate the IC functionality in an application like environment and to facilitate a simplified and convenient evaluation of the IC with a PC, an Infineon PSOC™ 4 microcontroller is added on the board as a gateway. The communication between PC and controller can be handled with a terminal software tool. The microcontroller section of the evaluation board can also be broken apart to allow the evaluation with other microcontroller types or as a break-out board.
Page 8: Diagnostics
IC and the USB port so that the board can be used with also with a terminal software tool without further programming effort. You can overwrite the firmware via the PSOC™ 4 programmer port connector using the Infineon MiniProg programmer tool to use your own software.
Page 9: Set Up The Evaluation Board Interface To The Pc
For using the board with YAT terminal, create a setup file or load an existing setup file. To simplify the usage of YAT, Infineon provides a setup file as a download that provides all commands needed to communicate with the evaluation board (ISO2H823V_B1v0.yat).
