2.7 Encoder Wiring (continued)
2.7.2 Single Ended Wiring
Figure T2.8 below shows how to wire the encoder inputs to both a single ended sourcing and single ended
sinking encoder outputs.
The encoder inputs on the SD4840EK are rated for 5 Vdc only. You must use a current
limiting resistor on each input if the outputs of your encoder are greater than 5 Vdc.
Appropriate current limiting resistors are shown in the figure below.
Because they are low power signals, cabling from the encoder to the SD4840EK should be done using a
twisted pair cable with an overall shield. The shield should be grounded at the end when the signal is gener-
ated, which is the encoder end. If this is not practical, the shield should be grounded to the same ground bus
as the SD4840EK.

2.8.1 Outline Drawings
Outline drawings for all of our motors can be found on our website,
www.amci.com
, in the

. The drawings are available as Adobe Acrobat pdf files. A document that is simply called
wiring
lists all of the wiring color codes for all AMCI motors. If you do not have internet access contact AMCI and
we will fax the information to you.
