FUNCTIONS & FEATURES

The R7E interfaces analog and discrete I/O signals with a PLC or PC via Ethernet Modbus/TCP nerwork.
A ‘basic’ module can be attached with an ‘extension’ 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.
Input sensor type (thermocouple, RTD) and range can be selected with the front DIP switches for all channels. In order to set different selections for individual channels, the PC Configurator Software (model: R7CON) is used.

RELATED PRODUCTS

• PC Configurator cable (model: MCN-CON or COP-US)
• PC configurator software (model: R7CON)
Downloadable at our web site.
• Clamp-on current sensor (model: CLSE)
For R7E-CT4E, the clamp-on current sensors must be ordered separately. Required number depends upon the channel number.
Note: PC Configurator Software is required to set IP address.

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.
■ 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.’
