Schneider 171CCC76010 M1/M1E Processor Adaptor

Product Overview

The 171CCC76010 connects M1 and M1E processors to I/O backplanes. You will find this adaptor in Momentum automation systems for hybrid applications. It converts processor signals into standard backplane communication protocols. Moreover, this adaptor provides electrical isolation between the processor and field I/O. Therefore, you protect the main CPU from voltage spikes on the backplane.

The 171CCC76010 stores no energy that requires any discharge procedure. Therefore, you can handle this adaptor immediately after power removal. Use the 20-pin header for direct processor connection. Meanwhile, the RS-232 port allows local programming access without removing the processor.

Installation and Compatibility

You can mount this adaptor on 35 mm DIN rail or a panel. Snap the 171CCC76010 onto the rail or use two M3 screws. Then connect the processor ribbon cable to the 20-pin header. Always verify the backplane power before inserting any I/O modules.

This adaptor works with all M1 and M1E Momentum processors. It auto-negotiates communication speed with the backplane. The 171CCC76010 replaces older 170 series adaptors without configuration changes.

Environmental and Safety Data

The 171CCC76010 operates from 0°C to +55°C. It withstands 3g vibration per IEC 60068-2-6 testing. The circuit board has a light conformal coating. Consequently, you can use this adaptor in clean industrial environments. Keep the RS-232 port dust cap installed when not in use.
