产品规格
iDAQ-5754 is a general-purpose timer/counter and digital I/O card. It is a compact-size add-on card for IBM AT compatible PC in control, monitoring and sensing applications. iDAQ-5754 has four 8254 chips which results in eight general-purpose 16-bit counters and two 32-bit timer. The counters can be set as independent counters or cascaded counters. The gate control of every counter comes from either external source or internal cascaded counters. The clock source comes from either internal timebase or external inputs, which can be selected by jumper setting. iDAQ-5754 delivers cost-effective and reliable digital output capabilities and are ideal for a broad variety of applications.
