Maximum Source or Sink
Current:
±25 mA
1
Current Excitation
Range: ±2.5 mA
Accuracy: See following TABLE: Voltage
Excitation Absolute Accuracy
(p. 109).

Exceeding current limits causes voltage output to become unstable. Voltage
should stabilize when current is reduced to within stated limits.
Voltage Excitation Absolute Accuracy

Temperature
(°C) Accuracy
0° to 40° ±(0.1% of s 1.2 mV)
–40° to 70° ±(0.1% of s 1.5 mV)
–55° to 85° ±(0.1% of s1.6 mV)

Note that ratiometric accuracy, rather than the absolute accuracy or excitation
or analog measurement, determines the accuracy of ratiometric-esistance
measurements.

Temperature
(°C) Accuracy
0° to 40° ±(0.11% of s 2.0 μA)
–40° to 70° ±(0.12% of s 2.5 μA)
–55° to 85° ±(0.13% of s 3.0 μA)

Note that ratiometric accuracy, rather than the absolute accuracy or excitation
or analog measurement, determines the accuracy of ratiometric-resistance
measurements.
6.1.3 Logic Levels — Specifications
Programmable terminals have two logic levels available for each pulse or digital
I/O function: 5.0 Vdc and 3.3 Vdc. If the CRBasic program does not specify the
logic level, the default is 5.0 Vdc. For current sourcing limits, see Omnibus
Current Source and Sink Limits — Specifications
(p. 124).
