FUNCTIONS & FEATURES

The R8 Series Remote I/O is composed of power/network modules, I/O modules and extension power supply module.
■ I/O MODULE
Performs data conversion of field inputs; Data conversion of data received through the internal bus into outputs.
■ POWER/NETWORK MODULE
The power/network module supplies the I/O modules with required internal electrical power source.
The power/network module changes the receiving data from internal bus into output signal and vice versa, acts as a gateway between transmission line and internal bus.
■ EXTENSION POWER SUPPLY MODULE
Inserted between I/O modules and supply the power when output current of power/network module is insufficient.
■ DATA CONVERSION
Depends upon the type of module and ranges.
For analog input module, 0 to 100 % of the selected range is converted into 0 to 10000 (dec) or 0000 to 2710 (hex). -5 to 0 % is represented in 2’s complements.
Analog output is represented with 16-bit binary data. 0 to 10000 (dec) or 0000 to 2710 (hex)
is converted into 0 to 100 % of the selected range.
-5 to 0 % is represented in 2’s complements.
For RTD, thermocouple input module at factory setting, data is represented with 16-bit signed binary data of engineering unit value (℃) multiplied by 10. e.g. In case of measuring 27.5℃, value is 275.
Refer to each model manual for details.
■ SCALING & ZERO & SPAN ADJUSTMENTS
The PC Configurator Software (model: R8CFG) is available to scale 0 to 100 % data. It is available to configure in the range between -32000 and 32000. e.g. Configuring temperature range by Configurator Software enables to handle 100 to 200℃ as value 0 to 10000.
■ HOT INSERTION/REMOVAL OF I/O MODULES
Since internal power supply and internal bus are performed through the connector of each module, it cannot be replaced with the power on.
■ DIELECTRIC STRENGTH
As dielectric strength differs depending on each module, refer to each specification sheet.

CURRENT CONSUMPTION

The I/O modules operate by the DC voltage (5 V DC) supplied from the power/network module. Arrange these modules in order that the total current consumed by these modules be within the supply current capacity. If the current consumption exceeds the limit, insert an extension power supply module. Even if total consumption current of the I/O modules is less than the supply current capacity, the total install number of the modules is max. 16. (Except extension power supply module)

USING EXCITATION SUPPLY

Some I/O modules use excitation supply, on the other hand some I/O modules do not. When excitation supply is cut off during power supply is on, operation is as the table shown below.

COMBINATION OF I/O MODULES

BASIC CONFIGURATION

The number of I/O modules that can be mounted changes depending on power/network module. Refer to the specifications of each power/network module for details.
Although Module address position can be set arbitrary, avoid from address overlap.
4-point analog I/O module takes two addresses per module. For example with the model R8-SV4N located at the module address 5, the inputs 1 and 2 are assigned to the address 5, and the inputs 3 and 4 are to the address 6. Do not assign another module to the address 6. All 4 inputs (input 1 through 4) can be used with Data Allocation 2, while only the inputs 1 and 3 can be used with Data Allocation 1.
Totalize pulse input 4 points module have 4 adresses available per module. Set to allocation area 2.
For modules which use more than 2 address, set address so that end address does not exceed 31. For totalize pulse input 4 points module, adddress should not exceed 28.
Only for rightmost module, set termination resistor to enable. Protective cover included for power/network modules.
