Ordering Information
Model Input Range Output Range
NOTES:
* Same specification as SCM7B39-01, -02, -03
(1) Output Range and Supply Current specifications are based on maximum output load resistance. Maximum output
load resistance is calculated by P
E
/I
OUT
2
where P
E
is the Output Effective Available Power that guarantees output range,
accuracy, and linearity specifications. Output effective available power is independent of supply voltage.
(2) Accuracy includes the effects of repeatability, hysteresis, and linearity.
(3)
Nonlinearity is calculated using the best-fit straight line method.
SCM7B39-01 +1 to +5V 4 to 20mA
SCM7B39-02 0 to +10V 0 to 20mA
SCM7B39-03 0 to +10V 4 to 20mA
SCM7B39-04 4 to 20mA 4 to 20mA
