Industry Pack Modules Industry Pack Modules IP235-x 16-Bit D/A Analog Output with RAM Buffer IP235 modules have a 16-bit D/A converter (DAC) to provide highly-accurate analog voltage outputs. An The IP235’s RAM buffer is useful for generating continuous waveform output cycles such as sine, triangle, or square signals. internal RAM buffer enhances control over the transfer of data to the DAC. Environmental Specifications Operating temperature: 0 to 70°C (IP235-4/8) Each channel has a dedicated 2K sample RAM buffer. Analog Outputs or -40 to 85°C (IP235-4E/8E models). All channels share a global clock. A start trigger Output configuration: 4 (IP235-4/4E) or 8 (-8/8E). Storage temperature: -55 to 125°C (all models). transfers digital values from the buffer to the DAC. D/A Resolution: 16 bits. Relative humidity: 5 to 95% non-condensing Four modes offer several choices for the data transfer. Output ranges: ±5V, ±10V, 0 to 10V MTBF: 815,720 hrs at 25°C, MIL-HDBK-217F, Notice 2. Continuous mode simultaneously updates all the (jumper-selectable). channels by cycling through the buffer until a software Power: +5V (±5%): 250mA maximum.

Single-cycle mode each channel. simultaneously updates all channels but only cycles Maximum throughput rate: Ordering Information through the buffer once for each start trigger. Outputs can be updated simultaneously or individually.
