Product:Yokogawa ALR121-S50 Serial Communication Modules ALR121-S50 in stock

The dual-redundant configuration can be provided by setting the serial communication modules on an adjacent slot. Each of the ALR111 and ALR121 modules has two ports; however, the dual-redundant communication requires two communication modules. The two sets of dual-redundant communication are enabled by two ports of ALR111/ALR121; however, the communication control is defined by each communication module. When one of the communication ports detects an error, both ports switch over the control/stand-by sides to the redundant module
