ABB TP857 3BSE030192R1 Baseplate For BC810

ABB TP857 (3BSE030192R1) is the baseboard (base) for the BC810 communication interface unit, part of the AC800M series. The TP857 connects the controller (CPU) and remote I/O stations (via the CEX bus). The baseboard itself does not participate in the main processing logic, but rather provides the infrastructure for physical connections, power distribution, and redundancy support. Together with the power/logic board, it completes the BC810 unit.

Function & Features

• The ABB TP857 baseplate supports building redundant communication systems. Typically, two interconnected BC810 units (one active and one standby) are required.

• The ABB TP857 baseplate receives external power and supplies power to the entire BC810 unit through its internal circuitry (such as voting diodes and fuses).

• The ABB TP857 baseplate provides connection points for all external interfaces, including the CEX bus and external power supply terminals.

• The ABB TP857 baseplate includes power voting diodes (for redundant power selection) and fuses.
