 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.
