Power Budget Check in an Un-powered State
Calculating DC Power Consumption
The UC600 is capable of providing 600 mA of power. Observe the following rules when budgeting
for DC power:
•
The UC600 can power a maximum of two small modules (WCIs, expansion modules) and a
maximum of 10 points configured as 4-20 mA In/Out (loop powered), simultaneously.
•
Include any additional devices where the UC600 is providing 24 VDC that are not part of the
current loop.
Use the following table to help determine your DC power supply needs.
Note:
If additional 0-20 mA inputs are needed, expansion modules can be powered from a PM014
power supply module instead of the UC600. See the “Tracer Expansion Modules IOM,”
BAS-SVX46-EN, for more details.
