26 Compact Combination Fast Analog I/O Module

Publication 1769-IN081A-EN-P - February 2007

Input Specifications

Attribute Value

Analog Normal Operating

Ranges

(1)

The over- or under-range flag will come on when the normal operating range (over/under) is exceeded. The module will

continue to convert the analog input up to the maximum full scale range. The flag automatically resets when within the

normal operating range.

Voltage: ± 10V dc, 0 to 10V dc, 0 to 5V dc, 1 to 5V dc

Current: 0 to 20 mA, 4 to 20 mA

Full Scale Analog Ranges

(1)

Voltage: ± 10.5V dc, -0.5 to 10.5V dc, -0.5 to 5.25V dc, 0.5 to 5.25V dc

Current: 0 to 21 mA, 3.2 to 21 mA

Number of Inputs Four differential or single-ended

Converter Type Successive Approximation

Response Speed per Channel Input filter and configuration dependent. See your user’s manual.

Resolution (max.)

(2)

Resolution is dependent upon your filter selection.

14 bits (unipolar)

14 bits plus sign (bipolar)

Rated Working Voltage

(3)

Rated working voltage is the maximum continuous voltage that can be applied at the input terminal, including the input

signal and the value that floats above ground potential (for example, 10V dc input signal and 20V dc potential above

ground).

30V ac/30V dc

Common Mode Voltage Range

(4)

For proper operation, both the plus and minus input terminals must be within ±10V dc of analog common.

±10V dc maximum per channel

Common Mode Rejection greater than 70 dB at 50 and 60 Hz with the 10 Hz filter selected,

respectively.

Input Impedance Voltage Terminal: 220K Ω (typical)

Current Terminal: 250 Ω

Overall Accuracy

(5)

Includes offset, gain, non-linearity and repeatability error terms.

Voltage Terminal: 0.15% full scale at 25 °C

Current Terminal: 0.2% full scale at 25 °C
