8051

These are processor-based computers compatible with the 8051. This is a very popular processor in embedded computers.

digital uPLC 
AT89S8253 processor based uPLC

This is a simple and inexpensive microcontroller board that provides 8 opto-coupled digital inputs, 8 relay outputs and a few internal peripherals.

Its features are:

  • ATMEL AT89c53 microcontroller running at 22.1184 MHz. This microcontroller is ISP, which means they can be reprogrammed. It is sufficient to connect a cable to the equipment by using the parallel port of a Windows computer.

  • 12 Kbytes of FLASH program memory (embedded in the microcontroller).

  • Real-time clock I2C bus. The clock battery-backed.

  • 2 Kbytes of EEPROM in microcontroller.

  • 8 Kbytes of EEPROM on I2C bus for data storage.

  • Serial port configurable as RS232C or RS485.

  • 8 optocoupled digital inputs.

  • 8 relay outputs with changeover contact with a capacity to drive resistive loads up to 10 A at 250 VAC.

The unit is supplied with two different finishes, basic finish and complete. In both cases the circuit and the microcontroller are the same, the difference is that the completed model includes RS485 transceiver, real-time clock with battery, memory eeprom by I2C bus and tray for mounting on DIN rail.

uPLC IV 
AT89C51RD2 processor based uPLC

Is an evolved version of the digital UPLC. It is mounted inside a box for DIN rail, we have added a small console with LCD display and 6 keys and has been equipped with a faster processor and more memory.

Its performance make it a powerful and flexible equipment on the market within the segment of small robots.

Voltage can be fed directly with 220VAC or 12VDC voltage. Optionally it can be supplied for use with 110VAC or 24VDC.

The main features of the unit are:

  • AT89C51RD2 microcontroller operating at 22.1184 MHz (the microcontroller executes instructions in 6 clock cycles instead of the usual 12 executed by the 51 family). It is sufficient to connect a cable from the unit to the serial port of a Windows computer.

  • External Watchdog can monitor system voltage and CPU status. IC can be configured by JUMPER to refresh automatically.

  • 64 Kbytes FLASH program memory (embedded in the microcontroller). 1.75

  • Kbyte SRAM for data memory.
  • Real time clock I2C bus. The clock battery-backed.

  • 8 Kbytes (expandable to 64Kbytes) of EEPROM on I2C bus for data storage.

  • Serial port configurable as RS232C or RS485.

  • 8 opto-coupled digital inputs.

  • 8 relay outputs of a contact with the ability to govern loads of 5A at 250 VAC.

  • 1 analog input configurable as 0 .. 10V or 0 .. 20mA.

  • 1 PWM transistor output (equivalent to analog output)

  • 2 LEDs in front controllable from the program.

  • 2x16 character backlit display. The backlight can be controlled from the software.

  • 6-key polycarbonate keyboard with tactile feel.

  • Buzzer sound.

    If desired, for series of more than 50 units, we can tailor print the screen on the front keypad.

uPLC V 
Processor AT89C51RD2 DIN rail

This microcontroller has been created to act as a control unit for an RS485 peripheral device network. All input / output lines have been removed, leaving only a communication port that can be used with the appropriate software as RS485 or RS232C.

Listed below are the features of this unit:

  • ATMEL 89c51RD2 microcontroller unit operating at 22.1184 MHz This IC has inside a program memory in a 64 Kbytes FLASH format that can be reprogrammed from a serial port on a Windows PC. Provides an addition of 1.75 Kbytes memory for data storage and 256 bytes as registers and program stack. It is sufficient to connect a cable from the unit to the serial port of a Windows computer.
  • External watchdog that monitors both CPU status and power supply. This can be automatically refreshed (only monitors voltage) or by software.

  • 128 Kbytes of EEPROM for data storage with the manufacturer's guarantee of 100 years data retention during power failure. This memory is accessible by internal I2C bus.

  • Real time clock with a maintenance battery . The clock has 56 bytes of nonvolatile SRAM. The clock is accessible from the internal I2C bus.

  • 4 LEDs visible from the front, controlled by software.

  • Piezo buzzer governable from software.
  • Internal microcontroller UART connectable by software to RS232 or RS485 ports.

  • Software ability to define by a second serial port (UART) connectable to RS232 or RS485 port. This ability to add a second serial port to the unit without additional hardware opens up new possibilities such as the installation of RS485 to the outside via a GPRS modem.

  • The unit comes in box to be set in a standard electrical panel with DIN Omega rail, providing all connections on pluggable terminal blocks.
