Emerson

1.Main Functions

• Analog signal acquisition: Collects standard 4–20mA analog current signals transmitted from field transmitters.www.plcva.com
• A/D conversion: Converts continuous analog field signals into high-precision digital data with 14-bit resolution for Ovation DCS controller.
• Multi-channel isolated sampling: Equipped with 8 independent isolated input channels, reducing crosstalk between different measuring points.
• High accuracy measurement: Captures process variables including pressure, temperature, flow rate and liquid level.
• Channel self-diagnosis: Continuously monitors channel faults, open circuit, short circuit and module health status, and uploads fault alarms to DCS system.
• Surge & overvoltage protection: Built-in surge suppression and isolation circuit to resist field interference and protect the backplane.
• Hot-swap capability: Supports on-site replacement without shutting down the whole DCS rack.
• Data transmission: Sends converted digital measurement data to Ovation controller for closed-loop process control and real-time monitoring.

Core summary: This Ovation analog input module receives 4-20mA analog signals from field instruments, converts analog signals into digital data, and transmits data to the Ovation DCS for real-time process monitoring and closed-loop control.plcva.com
