ABB TP857 Baseplate for BC810 I/O Module

Description

ABB TP857 (3BSE030192R1) Baseplate for BC810 I/O Module is a critical component in ABB’s industrial automation systems, specifically designed as the base component for the BC810 controller unit, pairing with the power/logic board to form the complete BC810 unit. It provides physical support and secure electrical connections for I/O modules and other system components, serving as the mounting point for CEX bus connectors and external power interfaces. Key features include high reliability, constructed with industrial-grade materials for strong mechanical strength and corrosion resistance, enabling stable long-term operation in harsh industrial environments with a working temperature range of -25 degrees Celsius to 70 degrees Celsius and an IP65 protection rating for dust and water resistance. Its modular design aligns with ABB’s automation system framework, allowing easy assembly, expansion, and integration with compatible controllers including PM857, PM861A, PM862, PM863, PM864A, PM865, PM866, PM866A, PM867, and PM891. The baseplate features multiple interfaces for power and signal connections, grounds to DIN rails via metal housing components, and includes external power voting diodes and fuses for enhanced electrical safety. It supports system redundancy, enabling online replacement of CPU baseplates in fully redundant setups without disrupting CEX bus traffic, and is widely used in manufacturing, process industries, power systems, and transportation for production line control, process monitoring, and equipment management.
