Adjustable Signal Generator for PLC Controllers

【Precise Signal Output】This multifunctional signal generator delivers a current of 0-24mA and a voltage of ±12V with remarkable calibration accuracy. The default settings of 4-20mA and 0-10V help technicians quickly diagnose PLC panels, ensuring reliable results for calibrating industrial equipment. 【Full Flow Safety】Equipped with short-circuit and reverse polarity protections to prevent accidental damage during field work. The power-off save function retains your last output values, saving electricians time and preventing frustrating data loss on-site. 【Adjustable PWM Control】This signal simulator offers a dedicated PWM output mode with an adjustable frequency of 1 to 150kHz and a duty cycle of 0 to 100 percent. This precise control allows engineers to perform accurate LED testing and motor speed adjustments, providing versatile performance for complex control systems. [Rechargeable Portability] Powered by a built-in 1500mAh lithium battery that provides up to 5 hours of continuous operation. The portable design frees maintenance technicians from power cables, enabling uninterrupted outdoor signal simulation and smooth testing across large factory areas. [Intuitive Visual Interface] The 2.0-inch color TFT screen displays all values clearly, allowing operators to quickly verify data in dark industrial environments. Combined with a large rotary encoder, this current and voltage simulator ensures rapid adjustments and smooth interface navigation.
