2-2.10 Expansion Card A Connections
A sticker identifying the Expansion Cards as A or C is located on each Expansion Card. The following
wiring diagrams show the Expansion Card in Slot 1. However, the Expansion Card may be in Slot 2, 3 or 4
based on the FMS configuration. The I/O for each card type appears on the back of the FMS for reference
during field wiring; see Figure 2-13 pg. 14 and Figure 2-16, pg. 16 for typical wiring. For information on
Expansion Card B, see APPENDIX H: Expansion Card B, pg. 127.
Expansion Card A has 12 non-isolated analog input channels and 8 relay output channels. The analog input
channels can be wired for 4-20mA, 0-5VDC, 0-10VDC, NO (normally open) dry contact or NC (normally
closed) dry contact. The circuit board has internal jumpers to select an mA input or a voltage input. The
factory default is set as a 4-20mA input. See APPENDIX A: FMS Expansion Cards, pg. 100, for jumper
location and settings.
