4. Isolated RS485 communication interface:
- Interface type: terminal block
- Direction control: automatically controlled by the main control hardware flow setting
- Interface protection: provides TVS diode protection, surge and static protection
- Matching resistance: default NC, reserved 120R matching resistor, can be enabled by jumper cap
5. Isolated CAN communication interface:
- Interface type: terminal block
- Direction control: hardware automatically determines and controls the data transmission direction
- Interface protection: provides TVS diode protection, surge and static protection
- Matching resistance: default NC, reserved 120R matching resistor, can be enabled by jumper cap
6. Indicator lights:
- PWR: power indicator light, connected to USB, turns red when voltage is detected
- RS485: RS485 indicator light: Green when data is sent from the RS485 interface, blue when data is sent back from the RS485 interface
- CAN: CAN indicator light, flashes when data communication exists at the CAN interface
7. Terminal power supply range: 7V - 36V
8. Shell: rail-mounted protective shell
9. Size: about 9.16 x 2.33 x 5.87cm
Feature:
1. Based on the ESP32-S3 single-chip microcontroller, it is equipped with an Xtensa 32-bit LX7 dual-core processor with a maximum clock frequency of 240MHz
2. It integrates 2.4GHz Wi-Fi and low-power Bluetooth 5 (LE) dual-mode wireless communication, featuring excellent radio performance
3. It has an isolated RS485 interface, facilitating the external expansion of various RS485 Modbus industrial expansion modules or sensors
4. It has an isolated CAN interface, facilitating the external expansion of various CAN devices
5. It has an edge connector interface, allowing for the connection of other devices
6. It has a USB Type-C interface, which can be used for power supply and download debugging, facilitating development use
7. It has an isolated wiring terminal power supply interface, supporting a wide voltage range of 7V - 36V, facilitating the use of industrial power supply ports
8. It has an RTC clock chip, supporting timing tasks
9. It has digital isolation to avoid external signal interference to the control chip
10. It has an integrated power isolation unit, which can provide stable isolated voltage, and the isolated end does not require additional power supply
11. It has RS485 receiver and transmitter indicator lights and CAN operation indicator lights, facilitating the perception of the devices operating status
