ESP32 Controller
Arduino-compatible ESP32 controller with 2 relay outputs, 2 transistor outputs, 2 opto-isolated inputs, 2 0/4-20 mA analog I/Os, 2 0-10 VDC analog I/Os and 4 GPIOs. Interfaces using USB, RS-485 serial, I2C, Wi-Fi or Bluetooth. DIN rail mountable.
The KTA-332 is a ESP32 Powered IO module for interfacing to real world applications. It's also an Arduino compatible controller and can be programmed with Arduino IDE for stand-alone operation.
A simple ASCII protocol allows control from Windows/Mac/Linux using either USB Virtual serial port drivers or RS-485. Additionally, multiple devices can be connected to one RS-485 bus, allowing control of many devices from one USB port.
Multiple controllers can be connected to one or more PCs in an RS-485 network. Each controller can be assigned an address and will respond to commands addressed to them.
