Product Description

The AAM11B S2 is a high-performance analog input module designed for Yokogawa industrial automation and PLC systems. It provides reliable acquisition of critical process signals, supporting both current (4–20 mA DC) and voltage (1–5 V DC) inputs.

Optimized for high-fidelity signal conversion, the module minimizes noise interference, ensuring precise monitoring of process variables. Its compact, narrow-profile form factor enables high-density installation in PLC racks or I/O nests, making it ideal for applications requiring efficient cabinet utilization without sacrificing measurement quality.

Technical Specifications

Application Scenarios

• Process Parameter Monitoring
  Continuous measurement of pressure, flow, level, and other analog process variables in chemical, pharmaceutical, or water treatment plants.

• Machine Feedback Control
  Interfacing with voltage-based encoders or current-output sensors in discrete manufacturing and automated machinery.

• Legacy System Upgrades
  Replacement or expansion of existing AAM series modules to extend operational life of Yokogawa PLC or DCS racks.

Product FAQ

Q: Can the AAM11B S2 handle current and voltage inputs simultaneously?
A: Yes. The module supports high-fidelity acquisition of both signal types, enabling mixed-signal measurement in the same I/O unit.

Q: Is the module hot-swappable?
A: Hot-swapping is only supported if the specific Yokogawa rack or backplane allows live module replacement. Otherwise, power down the system to prevent data loss or bus interruptions.
