2 ppendix : RX MPU Power udgeting RX MPU Power udget The RX MPU will automatically calculate the power budget, online or offline, taking into account the added expansion modules. However, since there is a limited amount of power available to supply the expansion modules, the power budget should be taken into account when designing a RX system, to be sure that the system will perform as expected. general rule of thumb is that when there are or more points of relay expansion modules in a system, a power budget calculation must be performed to ensure that there is enough available power to accommodate all expected modules. On the following pages you will find a worksheet and power budget tables to help you determine your system total power budget requirement. If the calculations exceeds the total available power, you may need to consider using an additional MPU or using a Remote I/O solution to satisfy the system requirements. Examples are also included to help show how the calculations should be performed. NOTE: The Power udget calculation applies only to backplane power supplied by the MPU or Remote I/O controller. Some expansion modules also require external power supplied directly to the module, which is not included in this calculation. WRNING: It is extremely important to calculate the power budget. If you exceed the power budget, the system Power udget Form. Find the Watts available for the RX MPU that you will be using. Put this value in line - MPU section of the worksheet.. If you are using a POM (Pluggable Option Module), find the watts consumed and put this value in line - POM section of the worksheet.. For each Expansion Module that you will be using, find the watts consumed and put this value in the appropriate slot that the module will reside in, lines through.. dd the values located in the POM Watts and Slot through, lines through. Write the value of this sum in line - Total Watts onsumed.. Subtract line - Total Watts onsumed from line - MPU Watts vailable. Write this value in line - Watts Remaining.. If the value in line - Watts Remaining is a negative number, your system is consuming more Watts than the MPU is capable of providing. This system would be unsafe as designed. You will need to reconsider your design. If the remaining wattage is zero or more than zero, the system design is good. - RX User Manual, rd Edition, Rev.
