4-20mA current and voltage signal generator with battery power supply interface, analog simulator, and adjustable 4-digit digital display.

1. Dual Current and Voltage Signals: This multi-functional signal generator kit can generate both current and voltage signals simultaneously with a single module. A 4 to 20mA current signal can be generated simply by rotating a multi-cycle precision potentiometer, making operation simple and convenient. 2. Clear LED Display: Our 4 to 20mA signal generator features a bright and clear 4-digit LED digital display for monitoring output current and voltage. The display content can be easily switched by pressing the switch below the display. 3. Current and Voltage Display Calibration: A current and voltage display calibration potentiometer is located on the back of the module. If the display is inaccurate, you can calibrate the current and voltage values yourself. 4. Wide Applications: Our signal adapter can be used in signal generators, valve regulation, inverter control, PLC debugging, panel debugging, LED testing, analog transmitter output, etc. 5. Excellent Performance: Dual modes of coarse and fine adjustment, with independently adjustable rotation counts. The minimum adjustment increment of the knob is 0.01mA, with the last value incremented by 1. After calibration, the actual error is 0.01mA, providing high-precision linear output. 6. Reliable performance: 4-digit 0.4-inch high-brightness digital display for clear visibility. Durable digital encoder knob, unaffected by environmental conditions. Power supply with reverse polarity protection. Output short-circuit resistant. <div class="wang-edit-text"><p class="wang-edit-text"><p class="wang-edit-text"><p class="wang-edit-text">Product Type: 4-20mA Current-Voltage Signal Generator Product Model: JS-020ISG-S-3L-J4 Current: 4-20 (mA) Material: ABS Color: As shown in the picture Weight: Approx. 58g/2.0oz<p class="wang-edit-text"><p class="wang-edit-text"><p class="wang-edit-text"><style> .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right ... } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } padding: 3px 5px; } .wang-edit-text table th { text-align: center; }</style> 1 x Signal Generator
