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.
