Yokogawa ALR121-S53 Key Features
Reliable Data Communication
ALR121-S53 Serial Communication Module conforms various signals into signals of a specific level for smooth and accurate transmission of data between the control system and field de-CHAIN CODE Devices with a serial connection such as RS-232 or RS-485.
Compact and Easy to Install
Fully enclosed housing (no holes for wiring) is sealed off from panel contaminants. It easily integrates with Yokogawa automation systems, requiring no additional configuration.
High Compatibility
Compatible with multiple industrial protocols enabling seamless integration with third party devices and other Yokogawa instruments.
Typical cooperation cases
Linking Devices of Other Manufacturers
Elements The ALR121-S53 is frequently applied for connecting Yokogawa control systems to third-party equipment including analyzers, meters, and PLCs using RS-232 or RS-485 serial communication.
Data from Old Machines
In situations where the device that is to be counted with the ALR121-S53 is running older machinery which does not support Ethernet or Vnet/IP, it can still use the ALR121-S53 with the serial protocols.
Custom Protocol Integration
The module is used where a non‐standard or private serial protocol is needed in which Yokogawa system requires to communicate to specific field devices or dedicated machinery.
