1 Model 7B30 may be used to measure a process current input by installing a 250 Ω current sensing resistor, such as Model AC1391, on the backplane. With this resistor, the current

loop is maintained even when the 7B30 module is removed form the backplane.

2 Includes the combined effects of repeatability, hysteresis, and nonlinearity.

3 Nonlinearity is calculated using best-fit straight line method.

4 Vz is the nominal input voltage that results in a 0 V output.

Specifications subject to change without notice.
