The TPMC600 is a PMC compatible module and has 32 digital inputs galvanically isolated by optocouplers. The individual inputs are separated in groups of 4 sharing a common ground input. These groups are potential free to each other. A high performance input circuit ensures a defined switching point and polarization protection against confusing the pole. All inputs have an electronic debounce circuit with a programmable debounce time.

All inputs can generate an interrupt. The signal edge handling is programmable.

The boards are available with front panel and back I/O;

Software Support (TPMC600-SW-xx) for different operating systems is available.
