Sensor Input Connections
NOTE:
Since common mode voltages
can exist on signal wiring,
adequate wire insulation should
be used and proper wiring
practices followed. As a rule,
output wires are normally
separated from input wiring and
from power wiring for safety, as
well as for low noise pickup.
TIP:
Input, power, and output
terminal blocks are a plug-in
type and can be easily removed
to facilitate module removal or
replacement without removing
individual wires.
Sensor wires are connected directly to the module input terminals at the bottom of
the module (the spring-loaded DIN clip side). Transmitter input signals are isolated
from output and power. Observe proper polarity when making input connections.
Refer to the example input connections on the following page.
•
Transmitter input signal is isolated from output.
•
Inputs are polarized. Observe proper polarity.
•
Input excitation 5VDC up to 20mA.
