Multifunction signal generator | calibrator | 4–20 mA | 0–30 V | 0–24 mA | TFT display | Type-C | 3000 mAh
Code: ES-SG-003AMultifunction signal generator designed for generating, simulating and testing voltage, current and standard 4–20 mA analog process signals.
This device is especially useful when working with PLC controllers, analog inputs, sensors, frequency converters, industrial automation systems, measuring equipment and control circuits. Using the signal generator, it is possible to simulate a sensor signal without a real sensor, check the controller’s response, identify the fault location and perform equipment diagnostics.

PLC analog input testing – helps check whether the controller correctly reads the supplied signal
Automatic signal modes – supports signal rise, fall and cyclic mode
TFT color LCD display – clearly shows the set and generated values
Integrated 3000 mAh battery – allows the device to be used without a constant power supply
Type-C charging – convenient and modern device charging
Fault diagnostics – helps determine whether the problem is in the sensor, cable, PLC input or control systemUsage
For automation specialists: Useful for automation specialists working with PLC controllers, analog inputs, HMI screens, sensors and process control systems. The device allows quick checking of whether the controller correctly reads a 4–20 mA or voltage signal.
For electricians: The device helps check automation panel connections, analog circuits, signal converters and control equipment. Instead of a real sensor, a test signal can be supplied to confirm whether the system operates correctly.
For industrial equipment maintenance specialists: Helps identify the fault location faster. The device can be used to check whether the problem is in the sensor, cable, PLC input, controller settings or the control program itself.
For engineers: Suitable for equipment commissioning, testing and adjustment work. It allows real process values to be simulated before the final field sensors are connected.
For laboratories and training: Can be used in training, testing and laboratory environments where it is necessary to understand the operation of analog signals, 4–20 mA process loops and the response of control systems.

This is not a standard multimeter – its main purpose is signal generation and calibrationFAQ
What is this signal generator used for?
It is used for analog signal generation, 4–20 mA process signal simulation, voltage and current signal testing and automation system diagnostics.Is this device suitable for testing PLC analog inputs?
Yes, it can be used to check PLC analog inputs. A set current or voltage signal is supplied, and the controller can be checked to see whether the value is read correctly.How does this device differ from a multimeter?
A multimeter usually measures voltage, current or resistance, while a signal generator can generate a set signal. This allows not only checking the circuit but also simulating the operation of a real sensor.What signals can be generated?
The device supports an adjustable current signal: 0–24 mA; a standard process signal: 4–20 mA; and a voltage signal: 0–30 V.Illustrative image may have been created using AI.
