的详细介绍Yokogawa Serial Communication Module ALR121
YOKOGAWA ALR111 and Yokogawa Serial Communication Module ALR121-S50 for FIO that a field control station (FCS) uses to perform serial communication with subsystems such as FA-M3. These serial communication modules can be mounted on field control units (AFV30 , AFV40 , AFV10 , and AFF50 ), ESB bus node unit (ANB10 ), optical ESB bus node unit (ANB11), and ER bus node unit (ANR10 ).
