SLC 500™ Analog Input Module 13

Publication 1746-IN006A-US-P

When wiring single-ended 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 single-ended
inputs.

IMPORTANT

The module does not provide loop power for analog inputs. Use
a power supply that matches the transmitter specifications.
