2-Wire 4-20mA Signal Generator for Panel-Mounted Current Sensing Solutions

No-source two-wire 4-20mA current loop, compatible with 2, 3, and 4 wire systems. Features 9 programmable output points for dynamic testing, with each point configurable for running time, A current, and B current. Digital encoder adjustment ensures stable performance unaffected by temperature or humidity. Supports connection to positive and negative terminals; the two-wire system operates safely regardless of wiring configuration and will not damage the meter. High precision and excellent linearity with output accuracy of 0.5% and display accuracy of 0.01. Offers coarse and fine adjustment modes for quick and accurate calibration. Output range可 be set to 4-20mA (for control devices) or 3-21mA (for debug signals). Display modes include actual current, 100.0%, and 50.0Hz, with an LCD screen featuring backlight. Provides linear output that is calibratable. Supports automatic or manual output mode. Configurable with 2-9 quick adjustment output points. Built with low-power chips, ensuring ultra-low power consumption, no heat generation, and stable output. Durable plastic housing designed for easy installation. System Operation: Parameter Setting (Rotate clockwise to increase, counter-clockwise to decrease, press knob to confirm): 1. Press and hold the knob for 2 seconds to enter parameter setting mode. Display shows parameter number F001. Press confirm to set the value of F001: 0 for coarse tuning, 1 for fine tuning. Press confirm again to save. 2. When parameter number FXXX is displayed, use + or - to modify the parameter number. To access advanced parameters: - Enter + - - + to access F002 - Enter + - + - to access F100 - Enter - + - + to access F200 Power supply voltage: 15V–30V Output range: 4-20mA / 3-21mA Display mode: Real Current / 0–100.0% / 0–50.0Hz Sampling resistance: Less than 500 ohms Output accuracy: 0.5% Display accuracy: 0.01 Color: As shown Material: Plastic Size: 79.5 x 42.2 x 24mm / 3.13 x 1.66 x 0.94 inches Package Contents: 1 x Signal Generator Note: Light reflection and differences in display screens may cause slight variations in color between the image and the actual item. Measurement error allowance is +/- 1–3 cm.
