Panel-mount PLC ACS

16-IModbus RTUEthernet

Designed to meet the requirements of the EN61850 standard, the ACS range is used to control and manage the power supply of electrical substations. The touch screen on the front panel allows ergonomic control of the installation: visualize, order, list and acknowledge defects, … The inputs / outputs are wired on the rear panel. They are designed to adapt to any type of power supply : 24Vdc, 48Vdc or 125Vdc. The IEC61850 protocol allows an integration into the global control system of the substation. More than 30000 ACS modular boards are installed to date.
