Product Overview
The JSH-44084A is an eight-circuit DC monitoring module with eight voltage inputs and eight current inputs. It measures voltage, current, power and accumulated energy for product burn-in testing, automated production inspection and equipment monitoring.
Each voltage channel uses linear optocoupler isolation and has a separate input reference. Current measurement uses closed-loop sensors with an 8.5 mm conductor aperture. RS485 and Ethernet versions support integration with compatible PLCs, industrial computers and monitoring systems.

1.Product Burn-In Testing
Monitor voltage, current, power and accumulated energy across eight DC test circuits. A connected host can record readings, compare test positions and apply acceptance limits during extended operating tests.
2.Automated Production Inspection
Collect electrical measurements from multiple DC circuits through one acquisition module. Select the input ranges and update interval to match the production test sequence.
3.Equipment Room Monitoring
Monitor compatible DC equipment feeds and send operating data to a supervisory system through RS485 or Ethernet.
4.Custom Automation Equipment
Integrate multiple voltage and current measurements into a PLC or industrial computer. Separate voltage input references support applications where monitored circuits do not share a common negative connection, subject to the module’s electrical limits.

FAQ
1. Does “8-channel” mean eight inputs in total?
No. The module has eight voltage inputs and eight current inputs, allowing voltage and current measurement for eight corresponding circuits.
2. Can it measure power and energy?
Yes. In addition to voltage and current, the module provides power, accumulated energy and maximum-value data.
3. Do the voltage inputs share a common negative terminal?
No. The eight voltage channels are individually isolated and do not share a common ground. Installation must still comply with the specified input and isolation limits.
4. How is current connected?
Pass one conductor from each measured circuit through the corresponding sensor aperture. The aperture diameter is 8.5 mm. Check conductor size and current direction before installation.
5. What is the fastest update interval?
The fastest selectable measurement update interval is 10 ms. Other options are 20, 40, 60, 80, 100, 400 and 1000 ms. The default is 100 ms.
6. Which model should I choose for AC and DC measurement?
Choose the JSH-44084A for DC applications. For AC/DC universal measurement, select the corresponding JSH-41084A version and confirm the required ranges and communication interface.
