The Series 3700 series offers a growing family of high-density and general-purpose plug-in
cards that accommodates a broad range of signals at very competitive pricing. The Series 3700
supports applications as diverse as design validation, accelerated stress testing, data
acquisition, and functional testing. This section provides information on the following:

Maximum power usage with Series 3700 cards
Plug in modules are capable of switching many relays at once which can take a substantial
amount of system power. There is a limited amount of system power available for switching
relays. Therefore, use care in order that Series 3700 maximum available power is not exceeded.
The maximum power available is limited on a per bank basis as follows:
From the table, the total power available for slots #1, 2 and 3 is 12,300mW (12.3W). Similarly,
the total power available for slots #4, 5 and 6 is 12.3W. Attempting to exceed these power levels
will result in the system performing as many of the operations as possible until these power
limits are reached. An error message will then be created and the remaining operations will not
be performed.
