Gateway, Remote I/O

R3 Series - Multi-channel, Mixed Signal Remote I/O

R3 Series

Wide selection of I/O modules and network modules.

  • Great flexibilities in number and type of I/O signals: DC current/voltage, temperature, strain gauge, AC current/voltage, AC power, etc.
  • Economical DC input module can handle fully-isolated 4 points up to non-isolated 16 points.
  • Hot-swappable I/O modules
  • Dual redundant communication networks

Products Line up

M3 screw terminal block is used for I/O modules. The removable terminal block is convenient for maintenance. Network Module and Power Supply Module in one housing. One I/O module plus one Network Module with power supply is the minimum unit: Space-saving and economical solution.
Dual network communication modules are optional for mission critical applications.
If you choose two different network protocols for the network modules, the remote I/Os can be directly monitored by two different manufacturers’ PLC systems.
