Voltage connection
Notes:
a. Shields should be connected at the signals source.
b. The 0V signal of the analog input must be connected to the controllers 0V.

Analog Inputs Two 10-bit, multi-range inputs:
0-10V, 0-20mA, 4-20mA
See Note 1 on page 1
Conversion method Successive approximation
Input impedance >150K
W for voltage
243
W for current
Galvanic isolation None
Resolution (except 4-20mA) 10-bit (1024 units)
Resolution at 4-20mA 204 to 1023 (820 units)
Conversion time Synchronized to scan time
Absolute max. rating ±15V/30mA
Full scale error ± 2 LSB
Linearity error ± 2 LSB
Status indication Yes, See Note
Note:
The analog value can also indicate when the input is functioning out of range.
If an analog input deviates above the permissible range, its value will be 1024.

Increasing Contact Life Span
To increase the life span of the relay output contacts
and protect the device from potential damage by
reverse EMF, connect:
a clamping diode in parallel to each inductive DC load.
an RC snubber circuit in parallel with each inductive AC load.
Each Output can be wired separately
to either AC or DC as shown below.
The 0V signal of the relay outputs is isolated
from the controllers 0V signal.
