US Digital

The PC3 provides single-ended, open collector outputs and includes a miniature switching power regulator that accepts a power supply from 9.5 to 32 volts. The PC3 is intended for applications where 5VDC is not available to power the encoder, or a higher voltage output from the encoder channel is needed. To achieve the desired output voltage range, add external pull-up resistors to the PC3 open collector outputs. The PC3 provides the added benefit of being a single-ended cable driver for cables up to 500 feet in length. 

Two versions of the PC3 are offered, a "header" version and an "inline" version. The header version (option H5) has hollow pins on the board that plug directly into the encoder. The inline version (options C5, FC5, LC5, and W5) connects to the encoder with a short cable.

Compatibility with US Digital products:

• PC3-H5 header version is used with the E2 and H1.
• PC3-C5 and PC3-LC5 inline verisons can be used with E2, E3, H1, and H3 encoders, and with the HEDS and EM1 optical encoder modules.
• PC3-FC5 inline version can be used with the "S" (single-ended) output versions of the E5, E6, H5, H6, H15, HB5M, and HB6M encoders, and T5, and T6 inclinometers. 
• PC3-W5 inline version can be used when customer wants five 12" individual discrete wire leads (no connector) on the input (encoder) end.
