When wiring singleĆended analog
input devices to the analog input
module, the number of total wires
necessary can be limited by
jumpering all IN-" terminals
together. Note that differential
inputs are more immune to noise
than singleĆended inputs.
Important: The module does
not provide loop power for
analog inputs. Use a power
supply that matches the
transmitter specifications.
Important: Follow the
guidelines on pages 3- 7 and
3-9 when wiring the module.
