Reliance Electric 57C404B Communication Network Module – Reliance Electric Automation Series
When a communication network module fails on the plant floor, the consequences are immediate and severe: production lines halt, data exchange between controllers and HMIs is severed, and engineers scramble to diagnose a fault that can cascade across the entire automation architecture. In high-throughput manufacturing, food processing, or power generation environments, even minutes of unplanned downtime translate directly into lost revenue and compromised safety. The Reliance Electric 57C404B Communication Network Module is the critical link that keeps your control network alive — its absence is not an option.
The 57C404B occupies a pivotal position within the Reliance Electric automation series, engineered to deliver robust, deterministic network communication between PLCs, drives, and supervisory systems. Reliance Electric — a brand with decades of heritage in industrial motion control and automation — built this module to meet the demanding requirements of continuous-process industries worldwide. The 57C404B remains a trusted component in legacy and hybrid automation systems across North America, Europe, and Asia-Pacific, where reliability and backward compatibility are non-negotiable.
