SG-004A Industrial Signal Generator with Programmable Output and Input Logging on a 2.4-Inch Color Display

The SG-004A is a handheld signal generator for industrial control testing. It can output and read voltage, current, frequency, thermocouple and resistance signals, with a 2.4-inch color TFT display for viewing readings and signal trends.

Key Features

• Programmable output supports increasing, decreasing and cyclic modes.
• Preset output, timed output and linear signal conversion provide additional control options.
• Real-time curves show input and output changes, with historical data recording.
• Supports MODBUS communication and a Modbus slave function.
• USB emulation provides a firmware upgrade connection.
• An ABS housing with a silicone surround and backlit display supports handheld use.
• Applications listed for the instrument include PLC system debugging, valve-positioner adjustment and instrument testing.
