2-2.2 Universal Input Connections
The eight non-isolated universal inputs are connected to TB2 and TB3. Universal input channels can be
individually configured through the FMS to monitor a 4-20mA signal, a Normally Open (NO) dry contact,
or a Normally Closed (NC) dry contact; see
Figure 2-3 for examples of typical sensor wiring. Refer to APPENDIX D: FMS Accessories Wiring on
page 109 for further details on wiring other RLE accessory sensors.
Some temperature and humidity sensors have internal jumper settings that may be used to select sensor
range and output voltage or current. Jumper settings should be set before power is applied to the
equipment. The sensor range (50-95°F, 22-122°F, etc.) should be documented at this time. The sensor
range is required to determine the gain and offset settings when configuring the input through software.
NOTE:
The Falcon has 24VDC available (TB2-1, TB2-2 +24VDC, TB3-9, TB3-10 24VDC
comm.) to power external sensors. The 24VDC external supply is internally fused at
300mA.
