Standard High-Density Universal
 Isolation of analog measurement and control signals with 2 way isolation (between input and
output) or 3 way isolation (between input, output and power).
 Conversion of analog signals from voltage to current. (i.e. 0...10V to 4...20 mA, etc.)
 Amplification, linearization, and transmission of low level sensor signals (i.e., mV signals from
thermocouples, etc.).
 Transmission of analog signals over long distances
 Provides local display using a splitter or remote status indications and alarms via relay contact
closures based on the analog signals.
The modules in the High-Density series provide cost-effective analog signal conditioning in a very
small package.
The Bulletin 931S Standard Series of analog signal conditioners provide solutions for a wide variety
of analog signals. They are available in compact sizes ranging from 12.5... 22.5 mm in width.
The Bulletin 931U Universal Series of analog signal conditioners are programmable, allowing the
devices to be used on a wide variety of analog signals. Two models are available, one in a 12.5mm
wide housing and one in a 45mm wide housing. Both are programmable using the same software.

Our analog signal conditioners are
designed to isolate, transmit, convert and
amplify analog signals in batch or
continuous process applications. They are
compatible with all types of integrated
PLC and DCS I/O systems. You can
integrate them with our PlantPAx™
Process Automation System to leverage a
single control platform for batch, drives,
motion control, process and safety.
