FEATURES
Interfaces, amplifies and filters input voltages from a J, K, T, E, R, S, B or N-type thermocouple. Module provides a precision output of either +1 V to +5 V or 0 V to +10 V, linear with input temperature. All 7B47 series modules are mix-and-match and Hot Swappable. FUNCTIONAL BLOCK DIAGRAM APPLICATIONS
Industrial signal conditioning Industrial signal isolation Industrial signal filtering Figure 1. 7B47 Functional Block Diagram PRODUCT OVERVIEW The 7B Series of signal conditioners feature small size, low cost and a wide output voltage range for a variety of applications including process control and factory-floor environments. The single-channel 7B modules accept inputs from a range of transducers and are fully rated over the extended -40oC to +85oC industrial temperature range. All 7B Series modules are rated for a nominal power supply input of +24 VDC; and, for maximum flexibility, they will accept supply voltages in the +14 VDC to +35 VDC range. The input modules, with the exception of the 7B21, provide a high-level output voltage that is factory configured for either the +1 V to +5 V or 0 V to +10 V range.
