Setup

Notes
CH 11 = I mode
470
Total Power
4970 m
W
NOTE
:
Since total power per bank cannot exceed
12300 mW, only 2 3750 cards per bank can
be populated when used in the example
configuration. This leaves spare power (12300
– (4970 * 2)) for controlling relays on a third
card in the bank.
Example 6
This example demonstrates how to calculate the card power of the 3750 when
used only as digital outputs.
Setup
Power
Notes
3300
Static power required of card under default conditions
(that is, all functions enabled)
CH 1 through 5 set as
OUTPUT
365 * 5 =
1825
CH 6 through 9 =
disabled
-730
Static power is reduced by disabling the totalizers
(channels cannot be individually disabled).
CH 10 = disabled
-820
Static power is reduced by disabling analog output
channel.
CH 11 = disabled
-820
Static power is reduced by disabling analog output
channel.
Total Power
2755
mW
NOTE
:
Bank power would not be exceeded if 3 cards
per bank were used in this manner.
Example 7
This example demonstrates how to calculate the card power of the 3750 for
digital inputs and two analog voltage outputs.
