Technical Specifications

Applications

The FSC 10020/1/2 module is widely deployed in industries where safety is paramount and fail-safe logic is required:

• Oil & Gas: Emergency shutdown systems (ESD), fire and gas systems (F&G), and blowout preventer logic.

• Refineries: Burner management systems (BMS), high-integrity pressure protection systems (HIPPS).

• Power Generation: Boiler protection and turbine trip systems.

• Chemical Processing: Toxic gas monitoring, interlock logic for hazardous operations.

• Water & Wastewater: Critical treatment process logic under safety constraints.

• Pharmaceutical: Bio-reactor control, hazardous area logic enforcement.

Installation Instructions

1. Power Down the FSC Rack before inserting or replacing the module unless hot-swapping is permitted and supported.

2. Insert the 10020/1/2 Module into the designated slot on the FSC backplane.

3. Secure the Locking Mechanism to ensure physical stability.

4. Connect Communication Cables for redundant Ethernet, RS485, or proprietary bus.

5. Configure the Module via FSC Engineering Tool, uploading the safety logic and validating using Honeywell diagnostic software.

6. Perform System Self-Test to ensure full recognition and functionality.

7. Commissioning: Conduct a full I/O validation and fail-safe test before operational deployment.

FAQs

Q1: What role does the FSC 10020/1/2 module play in a safety system?

A1: It functions as the logic solver, processing safety-critical signals and executing actions such as shutdowns or alarms when unsafe conditions arise.

Q2: Can the module be used in explosive environments?

A2: While the module itself isn’t certified for hazardous zones, it can control intrinsically safe field I/O via isolators and barriers.
