Portable Signal Generator, 4-20mA Voltage Current Signal Generator, 0-10V/0-22mA Adjustable Current Voltage Simulator Rechargeable Analog Signal Source Calibrator

High Precision Output - The voltage output of the current voltage signal generator is adjustable to ±10V, the error after calibration is <0.05V and the drive current is <20mA. The current output is adjustable from 0 to 22mA, the error after calibration is <0.05mA, turn the encoder knob to adjust the output voltage, can be calibrated; Support for coarse and fine adjustments - Portable signal generator Supports two coarse and fine adjustment modes, the number of adjustment turns can be set, simple operation. Built-in 3.7V lithium battery (1000mAh), the maximum charging current is 0.6A, it usually takes more than 4 hours to fully charge. Can be used for 1-5 hours. 3 Power Modes - This product has no built-in battery and can only be used while charging. The portable digital signal generator supports 3 power modes, it can be connected to a mobile phone charger, power bank or external 24V DC power socket. Other function – Voltage and current settings can be switched by a single button, the analog signal source calibrator adopts independent wiring and output can be performed simultaneously. The output features short-circuit protection and the power supply has reverse connection protection, which is safe and reliable. Current passive mode: the 3-AI+ PIN connects to 24V+, then exits through 4-AIO to control the external 24V current. Our meter is equivalent to an adjustable resistor; that's why it is called passive mode. Common current output power mode: our 4-AIO 6-GND output corresponds to PLC I+I-.
