Wire I/Os
Wire the XFC or XRC I/O ports to monitor or control external devices.
IMPORTANT NOTE: Refer to the XFC or XRC user drawings for I/O
wiring details for specific external devices. See
information.
NOTICE – Equipment damage. An external device can be powered
from VBAT or SW VBAT pins on the COMM terminals.
The output voltage at these pins is dependent upon the external
power supply connected to the CHRG connector (J5 on XFC, J17 on
XRC). The voltage range at J5 or J17 can be from 9 Vdc to 15.5 Vdc
The XFC and XRC are 12 Vdc nominal powered devices.
Before connecting an external device to VBAT or SW BAT, ensure
that the device is compatible with this voltage range. Connecting an
incompatible device may result in damage to the device.
Analog input (AI) pinouts
The XFC has two onboard analog inputs. Determine the AI and refer to the
pinout table for wiring.
IMPORTANT NOTE: The XFC AIs support voltage inputs by default. To
support current (4 – 20 mA) inputs add a 250 ohm resistor across the
+ and – terminals.
