Product Introduction
ABB MSR04XI is an industrial serial communications module designed for ABB’s Triguard SC300E control systems. It provides four RS‑232 serial ports plus a dedicated diagnostic port in a 9U plug‑in board form factor. The module enables communication between the main processor and external serial devices such as PLCs, HMIs, or sensor interfaces.
The MSR04XI supports configur able baud rates (9,600/19,200 bps) and provides 1 kV isolation between ports to reduce noise and protect system electronics. Front panel LEDs give real‑ time Tx/Rx and online status for field diagnostics. Single‑slot hot‑repair capability lets you replace a faulty communication board with system power maintained.
