cable types.
• Clamp-on current sensor (model: CLSE)
For R7M-CT4E, the clamp-on current sensors must be
ordered separately. Required number depends upon the
channel number.

■ STATUS
Analog input modules (models: R7M-SV4, R7M-TS4, R7M-RS4, R7M-MS4, R7M-CT4E) can show input status of
each channel.
Analog output modules (models: R7M-YS2, R7M-YV2),
discrete I/O modules (models: R7M-DA16x, R7M-DCx, R7M-DAC16x, R7M-RR8),

DATA CONVERSION
I 0 – 100% DATA CONVERSION
Analog input data is converted into digital representations of 0 – 100% proportional to each scaled range. The converted %
values are multiplied by 100 and expressed in 16 bits.
Overrange input is possible from -15 to +115% of the nominal range. When the signal exceeds the limit, the data is fixed at
-15% or +115% respectively. Negative value is represented in 2ʼs complements.

Engineering unit value °C or K is multiplied by 10 and expressed in 16 bits. °F data is represented in engineering unit

is represented in 2ʼs complements.

■ COUNT VALUE
The count value is 32-bit data. It is divided in 2 words of 16 bits represented with 2 addresses.The lower address is
allocated in the upper word (MSB) and the upper address in the lower word (LSB). The count value is 0 - 4 294 967 295.
The maximum count value available is 1 000 - 4 294 967 295. In case of overflow, the vaule is reset to 0 or 1
(configurable) from which the count will restart. The preset of the count value is also available. Use the R7CON or
commands for the configuration.
EXTENSION MODULE
A ‘basic’ module can be attached with one ‘extension’ module. The extension module is powered from the basic module.
By combining two modules, single station can handle mixed analog and discrete signals, 32-point discrete inputs, 32-point
discrete outputs, 16-point discrete I/Os and other combinations of signals.
Note: Relay contact 8 points output module can not be attached with an ‘Extension’ module.
■ OUTPUT AT THE LOSS OF COMMUNICATION
The extension module is set to ‘Hold Output’ by factory default setting. The PC Configurator software is used to change the
setting to ‘Reset Output.’
CONNECTING THE EXTENSION MODULE
1) Remove the extension connector cover located at the side of the basic module.
2) Connect the extension module.
3) Mount the combined module on a DIN rail.
