M4RTU/M4 I/O POWER CONSUMPTION WORKSHEET
Instructions
1.
On the previous worksheet, locate the daughter cards and digital and/or analog modules you will be
using with the M4RTU/M4 I/O. Enter a quantity for each item in the “Quantity” column. Also, fill in the
quantity and wattage of any RS-232 devices on the line provided.
2 . Multiply the value in the “Watts” column by the quantity entered in the “Quantity” column and enter
the result in the “Total” column for each component used.
Example:
Eight G4 digital module totals 0.688 W. Four G4ADX analog modules total 6.4 W.
3.
Add the values in the “Total” column, including the value entered for the M4RTU/M4 I/O base unit,
and enter the result on the “Total Watts” line.
Example:
0.688 W (digital modules) + 6.4 W (analog modules) + 7.5 W (base RTU) = 14.588 W.
4.
Enter the supplied input voltage for your installation on the “Your supplied input voltage” line.
Example:
24 VDC.
5.
Divide the total on the “Total Watts” line by the number entered on the “Your supplied input voltage”
line to calculate your total input current requirements. Enter this number on the last line of the
worksheet.
Example:
14.588 W (total watts)/24 VDC (supplied input) = 0.6 A required input current for the
M4RTU/M4 I/O.
