Features: 1. In signal source mode, the voltage source is adjustable from 0-10V and the current source is adjustable from 0-20mA 2. Multifunctional support for PWM mode, pulse mode, signal source, signal source mode, sine wave mode, and RS485 Modbus communication 3. The signal source mode of this module has voltage and current calibration function 4. Voltage, frequency, and duty cycle can be adjusted in PWM mode Specifications: Version: A-Standard Power supply voltage: DC 7-24V Product functions: PWM mode, pulse mode, signal source mode, sine wave mode PWM mode: Voltage, frequency, and duty cycle can be adjusted, with a frequency accuracy of up to 0.1%; Voltage range: 1-24V adjustable Frequency range: 1Hz-150KHz adjustable Duty Cycle range: 0.1-100% adjustable Pulse mode: time accuracy of 0.001S, starting delay time T0: 0.001-60S, high-level time T1: 0.001-60S, low-level time T2: 0.001-60S, number of pulses PulseNun: 1-60000 (unlimited output when the number is set to 0) Signal source mode: voltage source 0-10V adjustable, current source 0-20mA adjustable (note: load not 250R) Sine wave mode: 1-1000Hz adjustable, note: voltage to is around 5V and cannot be adjusted Signal load capacity: The maximum output current is 30mA (Note: This product outputs a signal source and cannot directly drive high-power loads. If you want to use PWM signals to drive high-power loads, such as motors, , etc., external drive modules can be used) Environmental temperature: -10-+70 Material: plastic colour: grey black Package Contents: 1 x Signal Generator Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
