Power Input (Port 1)
The SCU5 M operates under 24 VDC (± 5%) power with a maximum current requirement of 5 Amps. The
power is supplied through a Switchcraft DC power connector.
WARNING:
Supplying more than 24 VDC would damage the controller permanently.
WARNING:
A reverse polarity connection may also damage the controller permanently.
Switchcraft DC Connector
Sealed
power jack port option is available on the SCU5. A mating
plug connector or a pre-assembled
or a pre-assembled

to the tip/center pin and electronic ground on the sleeve pin. For the pre made cable assembly from
Roll-2-Roll the 24 VDC should be connected to the red cable and the electronic ground connected to the
black cable.

Grounding
For safety and for normal operation, the SCU5 M controller, the equipment to which the controller is installed
must be properly grounded. The metal enclosure surface or the mounting screws may be used to properly
ground the controller to the protective earth.
WARNING:
Please use all possible options to safely earth ground the controller. Improper grounding may
result in static buildup that can potentially result in malfunction of the controller.
Sensor Interface
Two sensor ports labeled Sensor 1 and Sensor 2 have industry standard 12-pin M12 connectors to connect
the 12-pin connector on the sensor cable. Either sensor ports can be used to connect the sensor(s) and the
controller will automatically recognize the connection.
WARNING:
The connectors are keyed and please DO NOT force the connectors. Forcing the connector may
damage the pins and eventually can damage the sensor and or the controller.
