2.3 I/O Connector Pin Out
The I/O Connector is located on the top of the module. The mate for this connector is included with the
SD4840EK. It is available from AMCI under the part number MS-2x11 and is also available from Phoenix
Contact under their part number 173 88 98. Figure T2.3 shows the pin out for the I/O connector.

2.4 Power Wiring
The SD4840EK accepts 24 to 48Vdc for its input power.

The
+Vdc Main
pin powers the entire module. This includes the control electronics and the motor

drive circuitry. AMCI strongly suggests using 18 AWG or larger wire for the power connections. The
MS-2x11 connector will accept up to 16 gauge wire.

The
+Vdc Auxiliary
pin powers the control electronics only. Using this pin is optional. By applying power
to this pin, you can remove power from
+Vdc Main
to remove power from the motor only. The control
electronics will remain powered and the drive will not lose its network connection. This feature was
incorporated into the design of the SD4840EK for customers that must remove power from the motor
due to safety considerations. Maximum current requirements on the +Vdc Auxiliary pin is 70 mA at
24Vdc.
The
+Vdc Main
,
+Vdc Auxiliary
, and
GND
connections each have two pins on the MS-2x11 I/O connector that are
internally connected together. You can wire to either or both pins for each connection.
The I/O connector is rated for a maximum current of 8 amps per pin. It is possible to
daisy chain the
+Vdc Auxiliary
connections, but AMCI strongly suggests avoiding this
practice for the
+Vdc Main
connections. It is strongly suggested to run separate wires
from your power supply to each drive for the
+Vdc Main
connections.
Do not apply 120 Vac to any pins of the SD4840EK. If this occurs, the unit will be dam-
aged and you will void the unit’s warranty.
