PEX-TMC12A PCI Express 12-ch Timer/Counter Board, 16-bit with 16 DI/16 DO
PCI Express x1 board with twelve 16-bit timers/counters, 16 TTL digital inputs and 16 TTL digital outputs. Designed as a replacement for the PCI-TMC12A series without software or driver changes.
- Twelve independent 16-bit timers/counters on four 82C54-compatible chips
- 16 TTL digital inputs and 16 TTL digital outputs, 500 kHz typical input response
- Timers can be cascaded to 32/48-bit and gates can use external signals or previous channel outputs
- Two jumper-selectable internal clocks: 8 M/1.6 M and 0.8 M/80 K
- Four interrupt sources with a more flexible interrupt mechanism
- Card ID function via SMD switch (4-bit) for multi-card systems

Product information "PEX-TMC12A PCI Express 12-ch Timer/Counter Board, 16-bit with 16 DI/16 DO"
The PEX-TMC12A is a PCI Express x1 board for engineers who need counting, timing and frequency measurement alongside general-purpose digital I/O in a single card. It provides twelve independent 16-bit timers/counters, built from four 82C54-compatible chips, and 16 TTL digital inputs and 16 TTL digital outputs.
Two onboard clock sources, 8 M/1.6 M and 0.8 M/80 K, are selected by jumper and give the timers a high-resolution reference. Timers can be cascaded to 32 or 48 bits, and each gate input can take an external signal or the output of another channel. A Card ID switch lets software identify the board when two or more cards are fitted in the same computer.
The card is intended as a direct swap for the PCI-TMC12A series, so existing software and drivers should not need modification. This ordering code, PEX-TMC12A CR, includes one CA-4002 D-Sub connector.
Applications
- Pulse, event and switch-toggle counting
- Frequency readings and elapsed time measurement
- Pulse-width measurement
- PWM output and pulse (square wave) generation
- Rate generation for industrial and laboratory applications
