Product Description
The AAM50 S1 is a high-reliability analog current output module designed for Yokogawa industrial control platforms, providing precise command signals to field actuators such as control valves, dampers, and variable speed drives. It ensures stable and accurate process control through standardized 4–20 mA DC output signaling.
The module features eight fully isolated output channels, effectively eliminating ground loop interference and protecting system integrity in electrically complex industrial environments. Its rugged construction supports a wide operating temperature range, enabling reliable operation in non-climate-controlled marshalling cabinets. With a slim form factor and efficient 24 V DC power design, the AAM50 S1 supports high-density installation within standard I/O racks and Field Control Stations (FCS).

Product FAQ
Q: Does the AAM50 S1 supply power to the current loop?
A: Yes. The module operates as a current-sourcing output, using its internal power conversion to drive the 4–20 mA loop.
Q: Why are isolated output channels important?
A: Channel isolation prevents electrical faults, ground noise, or wiring issues on one loop from affecting other outputs or the central controller, significantly improving system reliability and uptime.
