FNIRSI® SG-003A Signal Generator Adjustable 4-20mA 0-24V

From the shop's description

FNIRSI® SG-003A Signal Generator Adjustable 4-20mA 0-24V The FNIRSI SG-003A Signal Generator is a professional portable industrial signal calibrator and simulator designed for PLC debugging, industrial automation maintenance, process instrumentation testing, valve control testing, and analog signal simulation applications. The device supports voltage, current, frequency, and PWM signal generation and measurement functions, making it suitable for industrial engineers, automation technicians, and maintenance professionals working with industrial control systems. Features: Expect with the conventional signal input and output functions. Signals displayed as physical or engineering values, corresponding linearly. Voltage and current have automatic output function, it can choose a single rise, three modes of single drop and cycle. Four preset groups for quick output adjustment. With input to output conversion, voltage conversion active current mode, passive mode and current conversion voltage mode. The output has a custom function, the upper and lower output limits can be set arbitrarily. Displays input and output signal trends with adjustable sampling. Automatically adjusts curve within specified range over time. Voltage input diagram, current input diagram, the frame rate is 10 frames. PWM output can set frequency and duty cycle respectively. Real-time curve: Real-time observation of changes in voltage and current It is powered by a large-capacity lithium battery and is charged with a Type-c interface (5V).The capacity of the lithium battery is 3000mHA, fully charged in 4-6 hours, standby time is 26 hours, the using time varies, based on the usage(It can be 8-10 hours with 20mA continuous output) The high-definition TFT color LCD screen makes the reading more eye-catching. The resolution is 240×320.Low power consumption, Maximum power consumption: 0.32W FNIRSI SG-003A communicates via RS485 with configuration software or PLC. Firmware upgrade via USB emulated U disk.
