Connecting Power
The SmartController and sDIO require filtered 24 VDC power.
NOTE: Users must provide their own power supply. Make sure the power
cables and power supply conform to the specifications below.
24 VDC Power Specifications
Figure 2-6. User-Supplied 24 VDC Cable
NOTE: The power requirements for the user-supplied power supply will
vary depending on the configuration of the SmartController and
connected devices. A minimum configuration of the controller, front
panel, and pendant will require 2 A at 24 VDC. However, a 24 V, 5 A
power supply is recommended to allow for additional current draw from
connected devices, such as external IEEE 1394 devices and digital I/O
loads.
