Module Installation

The FP-AO-200 mounts on a FieldPoint terminal base (FP-TB-xx)
unit. The hot plug and play operation of the FP-AO-200 allows you
to install it onto a powered terminal base without disturbing the
operation of other modules or terminal bases. The FP-AO-200
receives operating power from the terminal base. Current loop
power is externally supplied.
To install the FP-AO-200, refer to Figure 1 and follow these steps:
1. Slide the terminal base key to either position X (used for any
module) or position 2 (used for the FP-AO-200 module).
2. Align the FP-AO-200 alignment slots with the guide rails on
the terminal base.
3. Press firmly to seat the FP-AO-200 in the terminal base. The
terminal base latch locks the FP-AO-200 into place when it is
firmly seated.
4. Connect a current loop supply for the outputs to the V and C
terminals of the terminal base.
I/O Module

Field Wiring

The FP-AO-200 sources current from an external loop supply to a
load (or field device). The terminal base provides connections for
both the external loop supply and for the eight output channels.
Figures 2a and 2b show examples of these basic wiring
connections. The positive terminal of the loop supply is connected
to the V terminal; the negative (or common) terminal is connected
to the C terminal. Each channel has an output terminal, I
common terminal, COM (internally connected to the C terminal);
