Buffer, Inverting, 24V Inputs to Open-Drain Outputs, 3 Channels
- Three unidirectional channels with inverting open-drain (sinking) outputs
- Optimized to accept 24V logic signals from a PLC with sourcing outputs
- Suitable for use as an inverting buffer
- Suitable for use as a logic voltage converter
- LEDs provide visual indication for all channels
- Inputs feature reverse-battery protection and overvoltage protection up to 35V
- Typical application: convert 24V PLC sourcing outputs to sinking outputs
- Mounting Options: Rubber Feet, Panel, or DIN Rail
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.

- 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.
