4-20mA Current Signal Generator – Adjustable Simulation Transmitter Module

Product Description

The 4-20mA Current Signal Generator Module is an adjustable analog signal simulator designed for testing, calibration, and troubleshooting industrial control systems. It generates an adjustable current signal from 0 to 20.00mA, making it useful for simulating transmitter outputs and testing devices that accept current-loop signals.

The module features a 4-digit digital display and an encoder knob for adjusting the output. It also includes a soft start/stop function for stable output changes and built-in short-circuit protection. The module uses active wiring and is suitable for applications involving PLCs, inverters, servo systems, valves, and other industrial control equipment.

Key Features

• Adjustable output from 0 to 20.00mA.
• 4-digit digital display.
• Encoder knob for convenient adjustment.
• Multi-rate function allows the displayed value to be configured.
• Soft start/stop for smooth and stable output changes.
• Built-in short-circuit protection.
• Active wiring configuration.
• Suitable for PLC, inverter, servo, and valve testing.

Technical Specifications

The specifications above are based on the product information listed on the Scientific Village Store product page

Applications

• PLC testing and calibration.
• Inverter signal testing.
• Servo system testing.
• Flow control valve testing.
• Industrial automation.
• Testing 4-20mA input devices.
• Simulating analog transmitter signals.
• Troubleshooting industrial control circuits.
• Testing and calibration of current-loop systems.

How It Works

The module is powered by a 15–28V DC supply, with 24V DC recommended. The encoder knob is then used to adjust the generated current signal. The output can be connected to a compatible PLC, inverter, servo controller, valve, meter, or other device that accepts an analog current signal.

Important: Although the product title refers to 4-20mA, the listed specification for this particular module states an adjustable output range of 0-20.00mA. Therefore, it can be adjusted within the 4-20mA range when required, but it is not limited to 4-20mA.
