Description
The ESP32 Industrial Interface Unit is an industrial-grade product originally designed and manufactured for monitoring, alarming and reporting with various input and output. The hardware comprises of one main PIC processor for I/O management, a secondary PIC processor for power and battery management, with a central ESP32 microprocessor with Bluetooth and WiFi capability.
Specifications
- Power Supply Voltages:
- Mains - 90 to 260 VAC 40-60 Hz
- DC - 9 to 36 VDC
- Includes input fuse DC, polarity protection, surge/spike protection and filtering.
- I/O Management (Main) PIC processor does all the analogue, digital and relay interface with isolated I2C communications to the ESP32. It will appear to the ESP32 as a peripheral with the I/O available via registers. The PIC can optionally reset the power to the ESP32.
- Two analogue inputs - 0-100 mV, 0-5 V, 0-1 V, 0-10 V, 0-100 V, ±100 mV, ±10 V, 0-22 mA, 4-20 mA, 0-1 ADC, 0-10 ADC, loop powered 4-20 mA. With DIP switch to assist in the configuration for each.
- A temperature input (RTD/pT100) with 0.5 to 2 mA excitation current.
- Precision AC and DC ±50 A current measurement.
- Isolated RS485/RS422 interface directly connected to ESP32.
- Isolated RS232 interface directly connected to ESP32.
- USB interface to dual UART interface as per ESP32 devleopment kit circuit.
- Power input goes through a current measurement.
- Low supply voltage detection, to enable graceful power down.
- Two digital inputs 5 to 30 VDC.
- Two switch inputs.
- Two relay outputs 250 VAC at 3 A max.
- On-board temperature sensor.
- Battery backed up real time clock.
- 4 LEDs for diagnostics and status.
- Buzzer.
The ESP32 industrial interface unit is not limited to the features above, other sensors/transmitter inputs such as: vibration, Loadcell, pH, ORP, thermocouple, conductivity and more, can be fitted for applications such as:
- Motor control and monitoring
- Production/factory machine management
- Industrial valve monitoring
- Freezer monitoring
- Pump monitoring
- Water quality monitoring and control
- and more
