Multi-channel, Scalable 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 communication networks
Depending on the model.
-
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. -
Front View
The Power Supply Module is located at the right end, with Network Module inserted at its left. Network Module with incorporated power supply is available for small systems.
Multiple I/O modules can be mounted; No.1 at the extreme left end, No.2 and following modules to its right. -
Hot Swappable I/O Modules
Each I/O and network module has an independent CPU.
Data is renewed by serial communications between modules. Therefore no momentary lapse or bumping of analog output occurs when switching communication buses in the dual communication mode.
Furthermore, removing or replacing modules does not adversely affect other modules on the same backplane. It is possible to replace them without removing the power supply. -

Current Consumption
The network and I/O modules operates by the DC voltage (20V) supplied from the power module. Arrange these modules in order that the total current consumed by these modules be within this capacity. If the current consumption exceeds the limit, reduce the number of modules to be supplied from the power module.

Basic Configurations
Single Communication Mode
Single network module with internal power supply; no power supply module
Single network module with external power supply module
Single network module with two external power supply modules
Caution:
No additional power supply module is available for the network module with internal power supply
Dual Communication Mode
Single power supply module
Two power supply modules
Caution:
Network module with internal power supply cannot be used for dual communication mode. Combinations of two network modules with internal power supply, or of a network module with internal supply and an external power supply is not possible.
One of the network modules must be set to 'Main', while the other must be set to 'Sub' with DIP switches at the side of the module.
R3 Series - 900 MHz Band Wireless Remote I/O
(for use in the US)
Modbus Interface Module (Model: R3-NMW1F)
Licence-free 900 MHz ISM band
FCC Part 15 compliant wireless module*
- Converting Modbus-RTU protocol into the 900 MHz band radio protocol and vice versa.
- Wide selection of R3 Series I/O modules can be freely combined.

System Configuration Example
When Gateway Function is Enabled
With PC as Modbus/Master, communicates with slave devices via wireless module using Modbus/TCP and RTU protocol.
Also, Gateway function allows to communicate with slave devices connected in multi-drop configuration with wired network, using Modbus and RTU protocol.
