6-8 Applying FLEX Ex Analog I/O Modules
Power Supply Considerations
When applying power, consider the certain characteristics of the wire
connecting the power supply output to a module’s power input. The wire
cannot exhibit more than:
• 0.1Ω of resistance (+V and -V combined)
• 800nF of capacitance
• 10µF of inductance
Typically, these restrictions will yield wiring lengths of not more than 3.5m
or 5.8m (1.5mm
2
and 2.5mm
2
wire respectively) without the use of special
wiring or wiring methods.
