The DNA-QUAD-604 is 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 has a maximum input frequency of 16.5 MHz and 32-bit counters.
The Index pin may be set to perform a variety of tasks. It may be set to (1) reset/load the counter immediately, (2) reset/load the counter on the next A/B cycle (low/low, low/high, high/low or high/high), (3) generate an interrupt, or (4) 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 volt 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.

About the “Cube”
UEI's innovative Cube architecture may be deployed in four configurations. The PowerDNA Cube is an Ethernet-based data acquisition and control device. The UEILogger is a high performance data logger recorder. The UEIPAC is a Linux-based programmable automation controller and the UEIModbus is a Modbus data acquisition and control slave. Each “Cube” consists of a core module (that holds the processor, OS, local memory and network interface) along with three or six open I/O slots or layers. Users configure their systems by selecting appropriate I/O boards from UEI's extensive offering of analog input boards (with resolutions of 16, 18 or 24 bits, inputs to 100V or 0-20 mA), analog output (to 40V), digital input/output, counter/timer, CAN bus interface, multi-port RS-485 and RS-232, and power conversion boards.
