Industrial Applications

1. Conveyor System Motor Voltage Monitoring

Small-scale automated conveyor systems require constant monitoring of low-voltage DC drive inputs to prevent overload or stalling. The M4N-DV-13 integrates perfectly into compact control cabinets, giving operators a clear numerical readout of DC voltages up to 19.99V to ensure the drive remains within its optimal operating window.

Problem Solved

Prevents unexpected motor faults and downtime by offering a clear, continuous reading of drive control voltage within highly space-constrained machine panels.

2. Industrial Battery Bank Status Indication

In backup power configurations utilizing 12V batteries, engineers need a dedicated local display for real-time cell state-of-charge tracking. The meter tracks fluctuations around the nominal 12V mark accurately down to 10mV resolution.

Problem Solved

Eliminates the need for manual multimeter checks by providing a permanent, high-visibility 12-24 VDC voltage tracking solution directly on the battery enclosure.

3. Automated Test Equipment (ATE) Voltage Verification

Quality control stations often test logic-level components or sensors requiring precise DC excitation voltages. The M4N-DV-13 can be embedded into custom testing rigs to visually verify that the exact test voltage is actively applied to the unit under test.

Problem Solved

Decreases human error in testing environments by providing a highly accurate (0.2% F.S.), rapid 300ms sampled visual confirmation of the excitation voltage before test routines execute.
