The Yokogawa PSCAMAAN 16404-500/3 is a Critical Analog Module (CAM) designed for ProSafe-PLC, Yokogawa's safety PLC system. This module is used in high-integrity safety applications, such as process shutdown systems (ESD, F&G, BMS).

Key Features & Specifications:

1. Function:

• Analog Input/Output Module for safety-critical control systems.

• Monitors analog signals (e.g., 4-20mA, 0-10V) from sensors (pressure, temperature, flow).

• Used in SIL2/SIL3 (IEC 61508) safety applications.

2. I/O Type:

• Analog Input (AI) or Analog Output (AO).

• Supports HART communication.

3. Redundancy & Diagnostics:

• Fault-tolerant design with self-diagnostics.

• Supports redundant configurations for high availability.

4. Isolation & Noise Immunity:

• Channel-to-channel isolation to prevent cross-talk.

• High noise immunity for industrial environments.

5. LED Indicators:

• Module status (OK, Fault, Active).

• Per-channel status for troubleshooting.

6. Compatibility:

• Part of ProSafe-PLC safety system.

• Works with Yokogawa ProSafe-RS and CENTUM VP.

Applications:

• Emergency Shutdown Systems (ESD)
