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 RIM-1000 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. See Appendix D, “RIM-1000 Accessories Wiring” on page 181, for further details
on wiring other RIM-1000 accessory sensors, or refer to our Rim-1000 Integration Guide.
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 Rim-1000 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.
