The Kappa4413USB is an isolated, USB-controlled 4–20 mA current loop transmitter (3-wire) based on the IS4413-M1 module. Generate a loop current from your PC without writing any firmware: just send simple text commands through a virtual COM port, from any serial terminal or your own Python script.

Ideal for testing and calibrating PLC analog inputs, simulating sensors, automating lab and production tests, or evaluating the IS4413-M1 before designing it into your own product.

**Features**

- 0 to 22 mA output, 12-bit resolution
- USB side galvanically isolated from the current loop
- Plain ASCII commands at 115200 baud: send `725` for ≈4 mA, `3640` for ≈20 mA
- Configurable power-up current, stored in EEPROM
- 24 V supply and loop output on a pluggable screw terminal (24V, GND, COUT)
- Micro-B USB, 49 × 19 mm, 7 g
