Features
Based on ESP32-S3 microcontroller with Xtensa 32-bit LX7 dual-core processor, capable of running at 240 MHz
Integrated 2.4GHz Wi-Fi and Bluetooth LE dual-mode wireless communication, with excellent RF performance
The outputs adopt Darlington transistors with optocoupler isolation, delivering higher drive capability with a sink current of up to 500 mA, and feature built-in flyback diode protection
Supports passive and active digital input, with bi-directional optocoupler isolation. The digital output supports digital input linkage control
Onboard isolated RS485 interface, for connecting to various RS485 Modbus industrial modules or sensors
Onboard isolated CAN interface, for connecting to various CAN devices
Onboard pin header, allowing access to other devices
Onboard USB Type-C port for power supply, firmware downloading and debugging
Onboard power supply screw terminal, supports 7~36V wide voltage input, suitable for industrial applications
Onboard RTC chip, supports scheduled tasks
Onboard W5500 Ethernet chip for extending 10/100Mbps network port through SPI interface
Built-in PoE module for PoE capability (compliant with IEEE 802.3af standard)
Onboard optocoupler isolation to prevent interference from external circuit
Onboard digital isolation to prevent interference from external signal
Onboard unibody power supply isolation, providing stable isolated voltage, no extra power supply required for the isolated terminal
Onboard TF card slot for external TF card storage of images and files
Built-in buzzer, RGB LED, power supply, RS485 and CAN TX/RX indicators for monitoring the operating status of the devices
Rail-mounted protective case, easy to install, safe to use
