ABB MLBL-05R Industrial Relay Module for Control Circuits and Automation

ABB MLBL-05R is a lamp block with an integrated red LED indicator designed to provide a clear, front‑facing status signal in ABB MP and MS control devices. Operating from 110 to 130 V DC, the red LED draws about 9.9 mA, delivering a visible cue within industrial panels without requiring a separate indicator module. The module carries ABB part number 1SFA611621R1051 and is intended for front‑mounting on mounting adapters such as MCBH-00 or MCBH-5-00 for MP/MS series equipment, enabling rapid installation in control cabinets. In automation applications, the MLBL-05R serves as a signaling element to convey states such as run, stop, or fault, complementing other ABB signaling components and matching the appearance and branding of ABB's modular plastic range. Designed for panel builders and machine integrators, MLBL-05R simplifies signal annunciation by providing a single, plug‑in LED indicator that aligns with ABB signaling arrays across the MP/MS family, ensuring consistent visual cues across ABB’s control circuits and automation setups.
