NORISYS 4 I/O modules

I/O slave module with 32 digital inputs


I/O module NORISYS4 32DI
  • 32 digital inputs
  • Robust design for harsh environments
  • Ideal for use in shipbuilding thanks to approvals from classification societies


The NORISYS 4 32DI is an I/O 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 32 independent inputs.
