PCI-TMC12A CR

Industrial PCI card with 12-ch Timer/Counter.

The PCI-TMC12A is a general purpose timer/counter card that supports the 5 V PCI bus and “Plug & Play” functionality to automatically obtain I/O resources from the BIOS. This card contains twelve 16-bit timers/counters (four 82C54 chips x 3 timers/counters), 16 TTL digital input channels and 16 TTL digital output channels.

The two onboard clocks (8 M/1.6 M and 0.8 M/80 K) are jumper selectable and provide a high-resolution clock source for timers/counters. Counters/timers can be used for industrial and laboratory applications such as pulse/event/switch-toggle counting, frequency readings, elapsed time measurement, pulse-width measurement, PWM (pulse-width-modulated) output, and pulse (square wave) and rate generation, etc.

Features:

• 4 onboard 8254 timer/counter chips
• 12 independent 16-bit timers/counters
• 12 external clock inputs
• 12 external gate control inputs
• 12 timer/counter output channels
• 16-bit timer/counter can be cascaded to create 32/48-bit timer/counter
• Gate input can be either an external signal or the output of a previous timer/counter channel
• Four interrupt sources
• Two internal clock sources
• 16 TTL D/I channels and 16 TTL D/O channels
• Drop-in replacement for PCI-TMC12 without any need for software/driver/wiring modification
• More flexible interrupt mechanism
• Hardware mechanism for the generation of two starting-clocks

Manufacturer's warranty: 12 months
