ACS : PLC for Substation Automation


The ACS range is suitable for High Voltage Switch management in electrical substations. Inputs/Output blocks are designed to control circuit breakers, switches and isolating switches.
Since 1997 the French national railway company (SNCF) has fitted their substations with our product.


ACS21 (modular format)


Hardware presentation


The hardware presentation is the same as LT160
with two additional secured I/O blocks :

- The secured Input/output block can control 4 high voltage switches (HVS). 
     For each HVS, the block has
        1 relay output to open the HVS
        1 relay output to close the HVS
        1 input "Opened HVS"
        1 input "Closed HVS".

The command of the open relay output is 4 times redundant.

- Input block :16 redundant inputs
