NORISYS 4 I/O modules

I/O slave module with 16 digital inputs and 8 relay changeover outputs


I/O module NORISYS4 16DI8R

  • 16 digital inputs
  • 8 relay changeover contact outputs
  • Robust design for harsh environments
  • Ideal for use in shipbuilding thanks to approvals from classification societies


The NORISYS 4 16DI8R is a slave module and is controlled by an N4 CPU master module. It acquires digital signals, such as the position of switches (limit switches, sensor switching outputs, operator switches and operator buttons), at 16 independent inputs. In addition, it is equipped with 8 relay changeover contact outputs that are independent of one another.
