An internal schematic is shown in the picture below. Darlington transistor array chips ULN2003 are used to buffer binary outputs in ET10. Each chip contains 7 transistors and handles up to 7 binary outputs. We recommend not to exceed 0.25A output current for each output pin (however ULN2003 maximum current is 0.5A according to the datasheet). | An internal schematic is shown in the picture below.
