ELECTRICAL CONNECTIONS
3.6 OUTPUT CONNECTIONS
This section describes the process output connections for the following output module types:
• 2003A Current Output Module(Section 3.6.1)
• 2005A Solid-State Relay Output Module (Section 3.6.2)
• 2007A Nonisolated Digital Output Module (Section 3.6.3)
• 2011A Dual Mechanical Relay Output Module (Section 3.6.4)
• 2011A Form C Mechanical Relay Output Module (Section 3.6.5)
3.6.1 2003A Current Output (AOM)
Make current output connections as shown in Figure 3-9.
When the instrument is installed in the European Union, an interface filter must be
connected in the signal wires to the module to comply with European Union (EU)
Electromechanical (EMC) requirements. Use a Phoenix Contact FILTRAB NEF1-1 or
equivalent. Reference Phoenix Contact Ltd., P.O. Box 131, D32819, Blomberg, Lippe,
Germany, Phone 52-35-320510.
