FNIRSI SG-004A Multifunctional Signal Generator & Process Calibrator

FNIRSI SG-004A Multifunctional Signal Generator & Process Calibrator. This highly portable device acts as both a signal transmitter and a measurement tool, engineered primarily for commissioning, programming, calibrating, and troubleshooting automation infrastructure (like PLC and DCS networks). Possible Applications: The SG-004A is extensively used by electrical engineers, field instrument technicians, and factory maintenance teams: PLC & DCS Debugging: Simulating analog sensor feedbacks (like 4-20mA or 0-10V loops) directly into industrial logic controllers to verify program logic. Proportional Valve Positioners: Calibrating electronic flow valves by injecting incremental control signals to ensure accurate positioning thresholds. Temperature Sensor Bench Testing: Emulating thermal resistance behaviors from Pt100 RTDs or standard thermocouples to test remote temperature transmitters. Frequency Inverter Calibration: Sourcing PWM and square wave speed references to verify speed adjustments on Variable Frequency Drives (VFDs).
