- Communication Mode: Point-to-point data transmission
- Protocol Support: Standard serial protocols with configurable parameters
- Data Rate: Up to 19.2 kbps per port
- Operating Temperature: 0°C to 55°C (32°F to 131°F)
- Power Consumption: Low-power design for energy efficiency
- Mounting: DIN rail or panel mount compatible
Application Scenarios
The ALR111-S50 excels in process control environments requiring reliable serial data exchange. Deploy this module to connect legacy instrumentation with modern SCADA systems, integrate barcode scanners or printers into production lines, or establish communication links between PLCs and operator workstations. Its dual-port architecture supports redundant communication paths or simultaneous connections to multiple devices.
Integration & Compatibility
Designed for seamless integration within Yokogawa CENTUM and ProSafe-RS systems, the ALR111-S50 also interfaces with third-party controllers and monitoring equipment. The module's standard RS-232C pinout ensures compatibility with a wide range of industrial devices, while configurable baud rates and parity settings accommodate diverse communication requirements.
Solution Benefits
Enhance system reliability with proven serial communication technology. The ALR111-S50's isolated ports protect against electrical noise and ground loops common in industrial environments. Its compact form factor conserves panel space, while hot-swappable design minimizes downtime during maintenance. Ideal for retrofitting older equipment or expanding existing control networks without costly infrastructure upgrades.
