2MLI-A21A Honeywell Photo Coupler Isolated Mixed Input Unit

First, 2MLI-A21A fully adapts to the entire Honeywell MasterLogic ML200 hardware ecosystem. Furthermore, it combines 8 AC input points and 16 DC input points in one compact unit. Moreover, universal optocoupler isolation protects circuits on all channels simultaneously. Besides, plug-in structure fits standard ML200 expansion slots directly. Meanwhile, lightweight body minimizes mechanical load on PLC mounting racks effectively.

First, the module supports wide AC voltage from 100 V to 240 V with ±10/-15% tolerance range. Furthermore, it works steadily at 50 Hz and 60 Hz power frequencies with 3 Hz deviation allowance. Moreover, typical input current reaches 14 mA at 50 Hz and 17 mA at 60 Hz operation. Besides, peak inrush current stays below 500 mA within 1 ms under maximum 264 VAC condition. Meanwhile, built-in input derating mechanism ensures safe operation under high-temperature industrial environments.

First, DC channels operate on standard 24 V supply with 20.4 V to 28.8 V working boundary. Furthermore, low ripple requirement below 5% guarantees steady signal sampling performance. Moreover, clear on-off threshold values eliminate signal misjudgment in field detection tasks. Besides, DC circuits hold no extra derating limits for continuous long-period operation. Meanwhile, strict off-state current control secures complete signal cut-off under idle circuit conditions.

First, the module applies reliable photo coupler isolation across all AC and DC input terminals. Furthermore, isolation barriers block surge interference between external circuits and internal PLC system. Moreover, complete separation avoids cross-channel signal coupling faults on industrial sites. Besides, isolated design extends overall service life of peripheral hardware components greatly. Meanwhile, stable optical coupling maintains consistent signal transmission in harsh electromagnetic environments.

First, compact slim enclosure resists workshop dust and basic electromagnetic interference efficiently. Furthermore, simple plug-and-play setup finishes installation without extra auxiliary tools. Moreover, unified terminal layout reduces wiring mistakes during on-site field assembly. Besides, extremely light 0.13 kg weight optimizes overall cabinet space arrangement perfectly. Meanwhile, consistent outline matches all standard ML200 I/O module mounting specifications fully.
