Features:
- High-Density 16-Channel Isolated Outputs
- Built-in Circuit-Open Detection
- Dual-Redundant Configuration with Fast Switch-Over
The YOKOGAWA AAI543-S50 S1 provides 16 individually isolated 4-20 mA channels, eliminating ground loop interference and simplifying wiring for large-scale I/O applications.
With automatic detection when loop current drops below 0.65 mA, the YOKOGAWA AAI543-S50 S1 enhances system diagnostics and helps operators quickly identify field wiring or device failures.
The YOKOGAWA AAI543-S50 S1 supports 1:1 module redundancy. When a failure occurs, the system switches to the standby module in ≤100 ms (standard response), minimizing production interruptions in critical processes.
The AAI543-S50 S1 YOKOGAWA Isolated Analog Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
