DAQM907A Multifunction Module

Keysight DAQM907A allows great flexibility for a variety of sense and control applications. It combines two 8-bit ports of digital input and output, a 100 kHz gated totalizer, and two ±12 V or ±24 mA analog outputs - all on a single earth-referenced module. The digital inputs and totalizer input may be included in a scan. Alarm limits for the digital and event counter inputs are evaluated continuously, capturing and logging alarm conditions even between scans. Also, it has two additional channels (Channel 6 and 7) that provide the ability to sense output current when sourcing voltage, or sense output voltage when sourcing current.

Key Features:

• 16 bits of digital input and output

• 100 kHz totalizer input

• Two ±12 V analog outputs or ±24 mA outputs

• Includes Certificate of Calibration

Digital Input/Output

Use the digital outputs with an external power supply to control microwave switches and attenuators, solenoids, power relays, indicators, and more. Use the digital inputs to sense limit switch and digital bus status. There are no complex handshake modes; reads and writes are initiated either from the front panel or the bus.

Totalize Input

Count events from devices like photo interrupters, limit switches, and Hall-effect sensors. It keeps an updated total which can be read via the front panel or programmatically at any time. With 26 bits of resolution, it can count events at full speed for nearly 45 minutes without an overflow.

Analog Output

Use the two electronically calibrated analog outputs to source bias voltages to your device under test, to control your analog programmable power supplies, or use the outputs as setpoints for your control systems. The outputs are programmed directly in volts, either from the front panel or from the bus.

DAQ970/73A Data Acquisition System Mainframe Highlights

The 3-slot mainframe for housing DAQ plug-in modules (sold separately) has the benefit of proven Keysight measurement performance, universal inputs with built-in signal conditioning, and modular flexibility, all in a low-cost, compact data acquisition package. Mix and match by choosing from 10 switch, RF and control plug-in modules to get just the functionality you need right now - then change or add more channels later as your application grows.

As accurate as the best bench DMM available, the DAQ970A/DAQ973A features 6 1/5 digits (22 bits) of resolution, 0.003% basic dcV accuracy, and ultra-low reading noise. Combine that with scan rates of up to 450 channels/sec, and you’ve got the speed and accuracy you need to get the job done right.
