Ergson E7S PLC

ERGSON E7S_PLC is a programmable logic controller unit for use in automation, control and monitoring systems.

  • Back




  Mounted in a panel


   221 mm x 138,5 mm x 75 mm (length x width x height)


  High performance ARM®32-bit Cortex®-M0 CPU, frequency up to 48 MHz

Peripheral Outputs

  8 relay outputs 16 A (rated 250VAC , 120 VAC, 30VDC) each, optocoupler isolated from the main circuit with external

  separated power supply. Status LEDs show the activity.


 Peripheral analogue Outputs

  U/I:  0–10V, 4 -20mA , with external separated PS

Peripheral Inputs

    8 galvanically opto-isolated digital inputs (triggered by 5-24V DC) with status LEDs for showing the activity. 

Peripheral analogue input                              

  U/I :  0–10V , 0-20mA, 4-20mA

ADC Input

   1 ADC input 18 bits of resolution low-noise, high accuracy ΔΣ A/D converter with differential inputs, on-board precision

  2.048V reference voltage, self calibration of internal offset and gain per each conversion, on-board programmable gain

  amplifier (PGA).

  1 ADC input 12-bit analog-to-digital performs conversions in single-shot or scan modes. In scan mode, automatic

  conversion is performed.


Communication Port

   RS485 isolated serial communication port (MODBUS RTU)

External communication port

  UART port for external serial communications

Peripheral USB port

   USB Full-speed device

Peripheral Bus port

   CAN Bus port connection


   SPI port connection


   I2C port connection

Customer Options

Optional: 1wire communication module for long line connection wich allows 100s of 1wire sensors.

Optional: high precision 24bit ADC module for direct load cell connections which allows weighing and batching     applications.

custom modules can be prepared
