Product Details
Description
The TU841 3BSE020848R1 provides fault-tolerant architecture by housing two independent communication modules on a single passive backplane. If one module fails, the redundant unit takes over the data traffic, keeping the I/O station operational. It routes the ModuleBus internally and offers terminal points for dual power supplies, improving electrical reliability. Designed for long-term stability, the unit has no active components, maximizing MTBF. The TU841 mounts on DIN rails and features mechanical keying to ensure safe and correct module installation.
