5.2.5 Wiring I/O Slaves to 1-5 V Sensors
The information in this section provides details for wiring the I/O Slaves Analog Inputs to 1-5 V
sensors.
Connecting a 1-5 Volt Sensor to Analog Input 1 or Analog Input 2
l
Analog Input 1 or Analog Input 2 screw terminal #8 and #10 are usable with 0.1 V to 5.625
V input voltages (compatible with most 1-5 V and 4-20 mA transmitters) and load the input
with about 100 Kohm to GND.

They also offer accuracy of ± 0.1% with 16-bit resolution and are recommended for the
most critical variables in a system.
