The TPMC117 from Tews Technologies is a standard single-width 32-bit PMC module that includes six independent channels operating as either a standard SSI (synchronous serial input) interface controller, an SSI "Listen only" device, an incremental encoder, or a general purpose counter. Each channel has a programmable data word length from 1-bit to 32-bit and isolated 24-V digital inputs. The board is ideal for motor control applications. Software support for major operating systems includes Windows, Linux, LynxOS, VxWorks, and QNX.
