KEHIPI

KEHIPI Adjustable 4-20mA Signal Generator 0-10V/0-22mA LCD electrical system tool

SKU CH-859R-GXC4H

Adjustable 0-10V and 0-22mA signal generator with LCD, built-in 1000mAh battery, and 0.01 precision for PLC calibration

  • Width8.7122 in
  • Adjustable 0-22 mA and 0-10 V output covers PLC and panel debugging
  • 01 V / 0.01 mA calibrated precision supports accurate sensor simulation
  • Built-in 1000 mAh 3.7 V battery with micro-USB or 15-30 V DC supply enables portable use
  • Encoder knob with 20 pulses per turn allows fine manual value adjustment
  • circuit, reverse-connection and charging protection safeguards connected equipment

Portable Signal Generator for PLC Debugging

This compact generator produces adjustable 0-10V voltage and 0-22mA current signals with 0.01 resolution for calibrating PLC controllers and panel meters. A built-in 1000mAh 3.7V rechargeable battery enables field use without mains power. The 8.7122 in wide ABS enclosure fits in a tool bag for on-site troubleshooting.

Verify Loop Compatibility and Power Options

Confirm the current loop sampling resistance does not exceed 500 ohms for accurate 4-20mA or 0-22mA output. The unit accepts micro USB 5V input at 0.2A or 1A, or an external DC supply between 15V and 30V. Two, three, and four-wire transmitters are supported in both passive and active modes.

Sustained Operation with Protection Features

The encoder knob adjusts output in 20 pulses per turn, and the last value is retained after power loss. Continuous operation is guarded by output short-circuit protection, reverse-connection protection, and charging protection circuits. Battery runtime depends on load; the generator maintains calibrated 0.01V and 0.01mA accuracy during extended sessions.

Questions about this item

What comes in the box and do I need to buy any cables or probes separately?

The package includes the signal generator, a USB cable, four clips, four insulation clip covers, a screwdriver, six terminals and a manual; no extra cables or probes are required for basic use.

Should I choose the voltage or current output mode for my PLC debugging task?

The generator provides both 0-10 V and 0-22 mA outputs with 0.01 V or 0.01 mA resolution; select voltage mode for analogue voltage inputs and current mode for 4-20 mA loop devices.

How accurate is the 0.01 mA resolution when the generator is connected to a real 4-20 mA loop?

After calibration the current output holds 0.01 mA accuracy with a sampling resistance up to 500 ohms, suitable for typical PLC analogue input modules.
