Canton, Mass. United Electronic Industries (UEI) released the DNA-QUAD-604, a four-channel quadrature encoder input board designed for use with the PowerDNA, UEILogger and UEIPAC data acquisition and control cubes. The board provides standard A, B and Z (index) inputs for each channel and is designed to handle quadrature applications with a maximum input frequency of 16.5 MHz, and 32-bit counters.
The index pin may be set to perform a variety of tasks including reset/load the counter immediately, reset/load the counter on the next A/B cycle (low/low, low/high, high/low or high/high), generate an interrupt, or generate a cube-wide trigger pulse. The counters may be read on software command or the board may be set to transfer the counter data into buffers at fixed timing intervals.
The DNA-QUAD-604 provides 4 digital inputs (in addition to the four A, B, Z channels) and 8 digital outputs. These digital I/O lines may be used as auxiliary digital inputs and outputs or configured as trigger in, trigger out, or clock-out signals for each of the channels. The digital I/O is compatible with both 5 and 3.3 V logic, and the digital outputs are rated to supply ±12 mA of drive current. The board offers 350 V of isolation and 7 kV of ESD protection.
Pricing: $695.00 each USD
