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.
