When defining a FieldPoint system that uses an FP-QUAD-510
module, you must calculate the power consumption. First refer
to the specifications section in the user manual for your network
module. The maximum number of terminal bases per bank
multiplied by 1 watt is the total power the network module can
supply. For example, an FP-1000 or FP-1001 can support nine
terminal bases (9
×
1 W = 9 W).
Next, refer to the specifications section in the operating
instructions for the I/O modules. Use the Power from Network
Module specification. For example, a bank of modules consisting
of four FP-QUAD-510 and five FP-DI-301 modules requires a total
of 6.4 W from the FieldPoint network module [4
×
(1.2 W) + 5
×
(0.325 W) = 6.4 W]. This power requirement is less than the 9 W
maximum and is therefore acceptable.
Installation
The FP-QUAD-510 mounts on a FieldPoint terminal base
(FP-TB-xx) unit. Because of its hot plug and play operation, you
can install the FP-QUAD-510 onto a powered terminal base
without disturbing the operation of other modules or terminal
bases. Although the FP-QUAD-510 receives operating power from
the terminal base, the input circuitry requires an external power
supply.
To install your module, refer to Figure 1 and complete the
following steps:
1. Slide the terminal base key to either position 8 (used for the
FP-QUAD-510 module) or position X (used for any module).
Note Although your module operates normally with the
terminal base key in either position, you should use the
position specifically for your module whenever possible.
By doing so, you avoid accidentally plugging an incorrect
module into a base once the base has been wired into the
system.
2. Align the FP-QUAD-510 alignment slots with the guide rails
on the terminal base.
3. Press firmly to seat the FP-QUAD-510 on the terminal base.
When the module is firmly seated, the terminal base latch locks
it into place.
