Product Overview

Bulletin 931 Analog Signal Conditioners

Analog Signal Conditioners are designed for use with Rockwell Automation I/O systems to provide reduced installation and maintenance costs in process applications. The products are available with two way isolation (between input and output) or three way isolation (between input, output and power).

• 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.
  

Bulletin 931H - High-Density Series

The modules in the High-Density series provide cost-effective analog signal conditioning in a very small package.

• Extreme high-density mounting (6 mm wide modules)
  
• Provide isolation and conversion solutions for a variety of signals
  
  • Current
    
  • Voltage
    
  • Temperature (thermocouples and RTDs)
    
• The DIP switches can be accessed from outside the housing
  
• Capability to jumper incoming power from unit to unit using standard Bulletin 1492 terminal block jumpers on most Bulletin 931H devices
  
• Wiring diagrams printed on outside of housing for ease of use in commissioning and maintenance activities
  
• End barrier is required for Cat Nos: 931H-P2A2N-OP and 931H-A1A1N-IP.
  

Bulletin 931S - Standard Series

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.

• Provide isolation and conversion solutions for a wide variety of signals:
  
  • Current
    
  • Voltage
    
  • Temperature (thermocouples and RTDs)
    
  • Frequency
    
  • Load Cells (bridge transducers)
    
  • Potentiometers
    
• Removable, plug-in terminal blocks are coded to eliminate wiring errors.
  
• The printed circuit board can be removed and re-installed without tools providing ease-of-use when accessing the internal DIP switches.
  
• Capability to jumper incoming power from unit to unit using standard Bulletin 1492 terminal block jumpers on some 931S devices.
  
• Jumper settings printed on outside of housing for ease-of-use in commissioning and maintenance activities.
  

Bulletin 931U- Universal Series

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 software.

• Provide isolation and conversion solutions for a wide variety of signals:
  
  • Current
    
  • Voltage
    
  • Temperature (thermocouples and RTDs)
    
  • Potentiometers
    
  • AC and DC current monitoring
    
• Removable, plug-in terminal blocks are coded to eliminate wiring errors.
  
• Programmable using software, which is bundled with the programming cable - Cat. No. 931U-CABLE.
