General Description

The BUFOI103A-24V provides 3 unidirectional channels that may each be used as an inverting buffer. It is ideally suited for converting 24V PLC sourcing outputs to sinking outputs. Inputs are optimized to accept 24V logic. The BUFOI103A-24V features overvoltage protection and reverse-battery protection on the inputs, and also features reverse-battery protection on the outputs.

This board includes terminal blocks to provide convenient access to the signals.

Applications

  • Convert PLC sourcing outputs to sinking outputs
  • Logic voltage conversion
  • Signal buffering and inversion


In this context, other names for buffers (or terms associated with buffers) are "signal amplifier," "logic level shifter," or "logic voltage translator."

Mounting Options

These products are available in two different mounting variants. Product numbers ending with -DIN come with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest 1/4" nylon standoffs under the mounting holes, and #6 screws.
