Yokogawa Models ALR111, ALR121 Serial Communication Modules

Models ALR111 and ALR121 Serial Communication Modules used with a safety control station (SCS) for performing Modbus communication. By using the SCS’s Modbus slave communication function, the data in SCS can be set or referred to by the Modbus, master which is as separate system from SCS via a serial communication module. Furthermore, the subsystem data such as from sequencers can be set or referred to via a serial communication module using SCS’s subsystem communication function.

These serial communication modules can be mounted on SSC60, SSC50, and SSC10 safety control units and SNB10D safety node unit that are connected with safety control units by ESB bus.
