These power calculations apply to E/M Series DAQ devices that p5 VDC at 1 A at the I/O connector. Refer to the
specifications for the E/M Series DAQ device. Tests were performed using a 1 m cable. Longer cables yield a lower level of
power, but the difference is negligible for cables of 2 m or less in length.

These power calculations apply to E Series DAQ devices that p5 VDC at 250 mA at the I/O connector. Refer to the
specifications for the E Series DAQ device. Tests were performed using a 1 m cable. Longer cables yield a lower level of
power, but the difference is negligible for cables of 2 m or less in length.

Refer to the
Calculating the Power Available from the SCC-PWR01
section.
* Subtract 0.08 W for the SC-2350 carrier due to its TEDS circuitry.
