FUNCTIONS & FEATURES

The R7ML, complying with MECHATROLINK-I and -II Intelligent I/O specifications, interfaces analog and discrete I/O signals with a PLC or PC via MECHATROLINK.
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, zero/span adjustments, scaling and temperature unit, use the PC Configurator Software (model: R7CON)

RELATED PRODUCTS

• PC configurator software (model: R7CON)
Downloadable at our web site.
A dedicated cable is required to connect the module to the PC. Please refer to the internet software download site or the users manual for the PC configurator for applicable cable types.

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.’
