BAT IQAN module switch DIN X Connecting a switch to DIN X and BAT Instruction book IQAN 16 Digital inputs Digital inputs DIN that share pins with VIN These digital inputs share pins with the module voltage inputs and have high impedance characteristics The preceding switch examples apply to these inputs DIN that share pins with CRET These digital inputs share pins with the return pins of the proportional output channels e g CRET and PWMRET These pins have an internal power clamping diode If used as inputs they must be connected in a way that prevents backending that is supplying power to the module from a source other than its power pin BAT Carefully read the following section for more information Connecting switches to the digital inputs When connecting switches to the digital inputs DIN that share pins with CRET extra precautions should be taken WARNING The DIN that share pins with the CRET positions of the proportional outputs have a possibility of gt backending the IQAN module when using those pins as digital inputs The internal circuitry has power clamping diodes between CRET pins and the internal power supply This arrangement creates a risk of inadvertently supplying power to the unit You can safely connect using VREF for the supply as shown in the preceding Connecting switches to the voltage inputs example If you would l2.
