PBB20

PBB20 is a fully buffered port that also combines the charge pump circuit and optional high voltage pre-regulator in a low cost interface solution for user who do not require optical isolation. Ideal for stepper driver boards with built in isolators that need more current than a standard parallel port can provide.

Specification

• Standard 25 way parallel port input socket.
• Each signal pin has its own terminal connection with input and output buffers.
• 20 mA Output buffers
• Low Logic level Charge Pump enable output
• All outputs disabled with interlock charge pump circuit.
• Blue Led indicator on power, plus red CP active signal
• Spare 5 and 12V output power rails.
• Pull-up resistors on all inputs for easy logic switching.
• Standard 8-35V power supply input or optional high voltage pre-regulator 15-70V.
