YOKOGAWA ALR121-S51 Serial Communication Module

YOKOGAWA ALR121-S51 Serial Communication ModuleThe YOKOGAWA ALR121 S51, also cataloged as the ALR121 Serial Communication Module, operates as a dedicated hardware component for executing half duplex serial data transmission and field device interfacing within CENTUM VP CS 3000 Field I O platforms. The hardware establishes connection methods via point to point RS 422 or multipoint RS 485 four wire systems utilizing start stop synchronization. Operating at transmission speeds ranging from 1200 bps

Vibration-Resistant Locking: The CC-MCARW1 incorporates a secure mechanical latching system that locks modules firmly into place

Q: How is the backplane bus current load affected when installing multiple modules

This makes the SDV531-S63 the preferred choice for offshore platforms and refineries where atmospheric corrosion typically degrades electronics
