1. Decentralized Hydraulic Pressure and Flow Monitoring
In heavy industrial hydraulic systems, pressure sensors and flow meters output continuous analog signals that need to be sent back to a central PLC over long distances. The DRT2-AD04 handles up to four 4-20mA signals directly at the machine level, digitizing them to 1/6,000 resolution and transmitting them reliably over DeviceNet to minimize analog signal degradation and line noise.
Problem SolvedEliminates analog signal degradation over long wire runs by digitizing multiple sensor inputs locally and transmitting via a robust DeviceNet fieldbus.

2. Automated Material Testing with Transient Peak Capture
During material stress or burst testing, temporary pressure spikes and peak load measurements occur extremely rapidly. Relying strictly on remote PLC polling times might cause these fleeting values to be missed. Utilizing the internal peak/bottom hold functions of the DRT2-AD04 allows the terminal to autonomously capture the highest 0-10V transient inputs natively at the hardware level.
Problem SolvedPrevents missed transient peak signals caused by PLC polling delays by handling peak/valley logic on the analog terminal itself.

3. Predictive Maintenance for Motor/Pump Degradation
To track the degradation of pumps, engineers monitor flow and vibration trends over time. The DRT2-AD04 allows internal rate-of-change (derivative) calculations. By interpreting gradual sensor shifts directly on the module, it triggers predictive maintenance alerts before a catastrophic failure, offloading this specialized logic from the central controller.
Problem SolvedOffloads complex rate-of-change calculations from the main PLC memory by utilizing edge-level Smart Slave math functions for predictive failure warnings.
