A 16-channel isolated analog output module by YOKOGAWA, model AAI543-H60 S1, designed for 4 to 20 mA signal transmission in industrial control systems.
- 16 isolated output channels for 4–20 mA signals
- Supports dual-redundant configuration for high reliability
- Module-level isolation between channels and system
- Multiple connection options: pressure clamp terminals, MIL cables, and dedicated KS1 cables
- HART communication capability for digital data exchange
-
