Detailed features: 12- channel 16 bit timer/counter ,16 digital input/16 digital output, 4 interrupt source,
FEATURES:
The PCI-TMC12A is a PCI-Bus general purpose timer / counter and digital I/O board. It provides tweleve channels of 16-bit timer / counter. Tw internal clock source (8M / 1.6M and 0.8M / 80K) are selected by jumper. Four 8254 chips provides a variety of powerful timer / counter function modes to match your industrail and laboratory applications.
