7B30

Overview
Isolated, Voltage or Current Input 7B30 FEATURES Interfaces, amplifies and filters unipolar and bipolar millivolt and voltage inputs.
Provides a protected precision output of either +1 V to +5 V or 0 V to +10 V.
A plug-in 250W current sensing resistor is provided to measure a process current input.
All 7B30 series modules are mix-and-match and Hot Swappable.

7B30 Functional Block Diagram PRODUCT OVERVIEW The modules feature a maximum nonlinearity of +0.
02% and are factory calibrated to guarantee a maximum accuracy specification of +0.
1%.
The 7B Series offers up to 1500 V rms continuous common The 7B Series of signal conditioners feature small size, low cost mode voltage isolation and 120 V rms of field wiring input and a wide output voltage range for a variety of applications protection.
The power supplies necessary to drive each of the including process control and factory-floor environments.
The single-channel 7B modules accept inputs from a range of www.
DataSheet4U.
com individual module’s input circuitry are internally isolated, enabling the 7B Series modules to offer true channel-to-channel transducers and are fully rated over the extended -40oC to isolation of the input signals.
+85oC industrial temperature range.
All 7B Series modules are rated for a nominal power supply input of +24 VDC; and, for The modules directly accept analog signals from maximum flexibility, they will accept supply voltages in the +14 thermocouples, RTDs, current loop powered transmitters, and VDC to +35 VDC range.
The input modules, with the exception other process control signals.
The 7B Series modules amplify, of the 7B21, provide a high-level output voltage that is factory linearize, isolate, protect and convert the transducer output configured for either the +1 V to +5 V or 0 V to +10 V range.
