analog input

analog input

Hardware interfaces that accept non-digital signals. For decades, all the plugs and sockets on traditional audio and video equipment connected analog lines. In addition, the common high-density DB-15 socket on a monitor is analog (see VGA). In the illustration below, BNC connectors have also been used for digital signals. Contrast with digital input.

It features two analogue input channels with multiple input ranges up to +/-10\7 and can sample data from both channels at an overall rate of 40 MS/s to the on-board memory, or continuously stream to a host computer at up to 8 MS/s.
The units feature eight 12-bit analogue inputs, two analogue outputs, eight digital I/Os and one 32-bit counter input.
The WM8711 is a replay-only device that includes an analogue input path to a volume control driver for sources such as external tuners or microphones while the WM8721 is a subset of the WM8711 without the analogue input.
The WSN-3226 node adds resistance-based measurements and features four analogue input channels that can be configured on a per-channel basis for +/-10V measurements or resistive measurements.
The node gives the flexibility to choose between high-speed and high-resolution analogue input modes on the device, optimising power and performance trade-offs for their applications.
Developed by Grant Instruments and based on the DT80 range, the DT82i features two analogue input channels, four digital inputs and four low-speed counters.
The DT82i's dual channel isolation technology allows up to four isolated or six common referenced analogue inputs. It also supports Modbus sensors and Scada systems, features switchable 12V and 5V regulated outputs to power sensors, and communications include RS232 and ethernet.
For added flexibility, there are an additional analogue output and two high-speed analogue inputs. Users can take advantage of one output for a meter to monitor speed and the other could be used to provide process information to another drive.
I/O enhancements include two 4-20 mA analogue outputs, more digital I/O and either 12 single ended 4-20 mA or six differential styles of analogue inputs. Super-compressibility options include AGA, Redlich-Kwong, and others.
The device features four single-ended 16-bit analogue inputs, with one ADC per channel, and a maximum sampling rate of 1.333MHz per channel.
