maximum of 300mA.
For the best system noise immunity, we recommend use of a separate,
linear regulated power supply for powering the input circuitry and the
encoder. You can use this supply for more than one absolute encoder
module or encoder, but do not use it for otehr 5V loads such as relays.
Make sure the power supply has enough additional current capacity for
the encoder.
We suggest you use extra shielded twisted pairs of wire in the encoder
input cable to power the encoder. If more than one extra pair of wires
remains, put them in parallel to reduce the voltage drop between the
power supply and the encoder Figure 3.4.
Do not source current, such as from a power supply, into the encoder
input terminals of the module. Doing so can damage input circuitry.
