PC6 Encoder to Counter Interface Board

The PC6 is no longer available for purchase.

PC6 Product Description

The PC6 decodes the quadrature outputs of an incremental shaft encoder to drive standard up/down counters. The PC6-U, up count / down count version, can be connected to the inputs of common counters such as a 74193 or 40193. The PC6-C, clock, and direction version, can connect directly to the counters such as 4516 or 74169.

Please note: The encoder interface IC used in this product can be purchased separately (see the LS7183N-S & LS7184N-S pages).

Index (Pin 2)

The index signal is routed unchanged, directly from the encoder.

PC6-U-x, pin 3 (LFLS7183).

Normally high, low-true. Down counts are enabled only when B leads A (clockwise rotation). One pulse is generated per encoder cycle using the PC6-U-1 and four pulses are generated using the PC6-U-4. For example, a 500 CPR encoder will produce five hundred clocks/rev. using the PC6-U-1 and 2000 clocks/rev. using the PC6-U-4. The external counter should count on the rising (high-going) edge of this output.

PC6-U-x, pin 5 (LFLS7183).

Normally high, low-true. Up counts are enabled only when A leads B (counterclockwise rotation). One pulse is generated per encoder cycle using the PC6-U-1 and four pulses are generated using the PC6-U-4. For example, a 500 CPR encoder will produce 500 clocks/rev. using the PC6-U-1 and 2000 clocks/rev. using the PC6-U-4. The external counter should count on the rising (high-going) edge of this output.

PC6-C-x, pin 3 (LFLS7184)

This output steers the external counter up or down. High = Up (A leads B), Low = Down (B leads A).

PC6-C-x, pin 5 (LFLS7184)

Normally high, low-true. One pulse is generated per encoder cycle using the PC6-C-1 and four pulses are generated using the PC6-C-4. For example, a 500 CPR encoder will produce 500 clocks/rev. using the PC6-C-1 and 2000 clocks/rev. using the PC6-C-4. The external counter should count on the rising (high-going) edge of this output.

Connector

The output connector on the PC6 is TE#640456-5.
