An 8-bit parallel microcontroller compatible interface allows connecting the inputs directly to a microcontroller or standalone circuit system. The input interface also supports direct control mode and is designed to operate with \u003cstrong\u003e3.3\/5V CMOS\u003c\/strong\u003e compatible levels. The signal transfer from input to output side is realized by the integrated \u003cstrong\u003eCoreless Transformer Technology\u003c\/strong\u003e. The board is designed for industrial applications such as process control and PLC to drive inductive, resistive, and capacitive loads like Relay, solenoid, lamps, heaters, piezo.\u003c\/p\u003e\n\u003cp\u003eThe input can be driven by applying \u003cstrong\u003e3.3V\/5V CMOS\u003c\/strong\u003e compatible signals to connector CN1. It can operate in microcontroller Mode by using Chip Select and Write Signals or in Direct Control Mode by closing the Jumper \u003cstrong\u003eJ1 and J2\u003c\/strong\u003e and setting the Data Input from \u003cstrong\u003eD0 to D7\u003c\/strong\u003e. The Output consists of 8 Channel High Side Switches with \u003cstrong\u003e0.6A\u003c\/strong\u003e Current rating. The Output is protected with a channel selected \u003cstrong\u003eover-temperature\u003c\/strong\u003e switch (to off). The 8 high-side power switches are controlled by means of the integrated parallel interface. The interface is 8-bit μC compatible. Furthermore, a direct control mode can be selected that allows the direct control of the outputs \u003cstrong\u003eOP0…OP7\u003c\/strong\u003e by means of the inputs \u003cstrong\u003eD0…D7\u003c\/strong\u003e without any additional logic signal. The \u003cstrong\u003eμC\u003c\/strong\u003e compatible interface allows a direct connection to the ports of a microcontroller without the need for other components. Each of the 8 high-side power switches is protected against short to \u003cstrong\u003e+DC (VBB)\u003c\/strong\u003e, overload, over-temperature, and against over-voltage by an active Zener clamp.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e+DC(VBB) Load Power Supply 11V to 45V (CN2)\u003c\/li\u003e\n\u003cli\u003eLogic Supply input Side 3.3V to 5V (CN1)\u003c\/li\u003e\n\u003cli\u003eLED D1 Power LED Logic Supply (Input Side)\u003c\/li\u003e\n\u003cli\u003eLED D2 LED On When (overtemperature or Vbb (+DC) below ON-Limit is detected)\u003c\/li\u003e\n\u003cli\u003eLoad CN3 to CN7\u003c\/li\u003e\n\u003cli\u003eInterface 3.3\/5V CMOS operation compatible\u003c\/li\u003e\n\u003cli\u003eParallel interface\u003c\/li\u003e\n\u003cli\u003eDirect control mode\u003c\/li\u003e\n\u003cli\u003eHigh common-mode transient immunity\u003c\/li\u003e\n\u003cli\u003eShort circuit protection\u003c\/li\u003e\n\u003cli\u003eMaximum current internally limited\u003c\/li\u003e\n\u003cli\u003eOverload protection\u003c\/li\u003e\n\u003cli\u003eOvervoltage protection (including load dump)\u003c\/li\u003e\n\u003cli\u003eUndervoltage shutdown with auto-restart and hysteresis\u003c\/li\u003e\n\u003cli\u003eSwitching inductive loads\u003c\/li\u003e\n\u003cli\u003eCommon output disable pin\u003c\/li\u003e\n\u003cli\u003eThermal shutdown with restart\u003c\/li\u003e\n\u003cli\u003eThermal independence of separate channels\u003c\/li\u003e\n\u003cli\u003eCommon diagnostic output\u003c\/li\u003e\n\u003cli\u003eESD protection\u003c\/li\u003e\n\u003cli\u003eLoss of -GNDBB (GNDbb) and loss of +DC(Vbb) protection\u003c\/li\u003e\n\u003cli\u003eReverse Output Voltage protection\u003c\/li\u003e\n\u003cli\u003eIsolated return path for DIAG signal\u003c\/li\u003e\n\u003cli\u003e+DC (Vbb) monitoring\u003c\/li\u003e\n\u003cli\u003ePCB dimensions: 87.49 x 62.07 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTesting the Project\u003cstrong\u003e \u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDirect mode:\u003c\/strong\u003e  CLOSE the Jumper J1, and J2, open the Jumper J3, Connect the Load between OP to GDB, apply load power supply to CN2, apply logic supply to CN1, Output will be default high due to pullup Resister network on input, pull down the input pin D0 by connecting to GND or using micro-controller, the output will be OFF.  LED D1 Power LED for logic supply, LED D2 turn ON When overtemperature or Vbb (+DC) below ON-Limit is detected.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eJumper J3 (DIS) DIS (Output disable) Jumper J3 Close = Disable Output, Open Enables the Output\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe high-side outputs OUT0…OUT7 can be immediately switched off by means of the low active pin DIS that is an asynchronous signal.

The system microcontroller selects the \u003cstrong\u003eISO1H811G\u003c\/strong\u003e by means of the CS pin. Whenever the pin is in a logic low state, data can be transferred from the μC. \/WR – Write. The system controller enables the writing procedure in the ISO1H811G by means of the signal WR. A logic low state signal at pin WR writes the input data into the input latches when the CS pin is in a logic low state. D0…D7. The parallel input data is transferred to the input latches with a high-to-low transition of the signal \/WR (write) while the \/CS is logic low. Then a low-to-high transition of \/CS transfers the data of the input latches to the output buffer. The μC Control Mode can be operated by connecting a Processor Board to the corresponding Signals of Connector CN1.
