Process industry


Finnish Fibreboard Ltd. produces and markets a wide range of LION hardboard products, the main end uses for which are the building, door and furniture industries.

Main selection reasons
  • Reliable control of large contactors
  • Long unshielded AC signal cables

Finnish Fibreboard's Heinola plant uses Siemens controllers interfaced to the plant with Delcon's relays. Delcon's interference suppression technology ensures correct operation of the input signals from plant switches even though cabling is long and there are many unshielded AC cables in the same core. Most of the AC output lines are switching large contactors where the large inductive nature of the load proved too difficult for alternative products.
