OPERATING INSTRUCTIONS
FP-DO-400
8-Channel, 5 to 30 V Discrete
Output Module
These operating instructions describe the installation, features, and
characteristics of the FP-DO-400. For details on configuring and
accessing the FP-DO-400 over a network, refer to the user manual
for the particular FieldPoint network module you are using with
the FP-DO-400.
Features
The FP-DO-400 is a FieldPoint discrete output module with the
following features:
•
Eight discrete output channels
•
Sourcing outputs supply 2 A per channel, 9 A
•
Compatible with voltages from 5 to 30 VDC
•
On/Off LED indicators
•
Hot plug and play operation
•
3,000 V input to output isolation
•
Double insulated for 250 V safe working voltage
•
–40 to +70 °C operation
Installation
The FP-DO-400 mounts on a FieldPoint terminal base (FP-TB-xx)
unit. The hot plug and play operation of the FP-DO-400 allows you
to install it onto a powered terminal base without disturbing the
operation of other modules or terminal bases. The FP-DO-400
receives operating power from the terminal base.

- Page 4 Discrete Output Circuit The discrete outputs of the FP-DO-400 consist of optically- isolated sourcing outputs. In the ON state, a transistor is turned on between the positive external supply voltage (the V and V terminals) and the output (V ) terminal. In the OFF state, this transistor is turned off, allowing only a small leakage current to flow.

- Page 6 Isolation and Safety Guidelines Caution Read the following information before attempting to connect any circuits which may contain hazardous voltages to the FP-DO-400. This section describes the isolation of the FP-DO-400 and its compliance with international safety standards. The outputs are isolated from the backplane provided by the terminal base with an optical isolation barrier designed and tested to provide protection against fault voltages of up to 3000 Vrms.
