The DM307 module is a powerful multifunctional interface for the modular DAQ3120 data recording system from B&K Precision. It extends the system beyond pure measurement tasks to include flexible digital inputs/outputs, a fast counter (totalizer) and two programmable analogue outputs - ideal for controlling test setups, generating signals or counting pulses.
The DM307 module is ideal for:
- Automation and control of test benches
- End-of-line tests in production
- Counting and monitoring tasks (pulse/flow counters, clock and event counting)
- Simulation of sensor signals via analog outputs
- Alarm and trigger applications in test and long-term measurement systems
Product features:
- Multifunction module for expanding the DAQ3120 with control and generation functions
- 16-bit digital I/Os via two 8-bit ports for controlling external devices or reading in digital signals (up to max. 42 V)
- 1 totalizer input for counting pulses with frequencies up to 100 kHz
- 2 high-resolution analog outputs (DAC) with 18-bit resolution
- Programmed output of voltage up to ±12 V or current up to ±24 mA per output
- Continuous monitoring of alarm limits at digital and totalizer inputs - alarm limits can be set at any time
- . and totalizer inputs - alarm events are also logged between scans
- Sense channels for monitoring voltage or current during signal output
- Seamless integration into the DAQ3120 system with convenient configuration via front panel, PC software or web interface
In contrast to the multiplexer modules DM300, DM301, DM303 and the high-voltage module DM309, which feed measurement signals to the integrated 6½-digit DMM of the DAQ3120, the DM307 focuses on control, counting and signal generation tasks. The DM300 with up to 450 channels/s is suitable for fast, fully isolated scanning of voltage signals. If you need universal voltage and current measurement, choose the DM301 with 20 multiplexer channels plus 2 current channels up to 1 A. The DM303 with 40 single-ended inputs offers a high number of channels for voltage measurements, while matrix circuits can be realized with the DM304 as a 4×8 cross circuit. The DM308 with 20 relay contacts is available for switching and actuating loads up to 300 V and 1 A, while the DM309 enables measurements up to 600 VDC or 2 A - ideal for demanding power applications. The DM307 perfectly complements these measuring and switching modules when digital control, pulse counting and precise analog output signals are also required.
