10101/2/1 HONEYWELL 10101-2-1 DI MODULE

HONEYWELL 10101/2/1 FSC Digital Input Module, the input stage operates in a "fail-safe" mode, ensuring that in the event of a component failure, the input signal de-energizes the processor, which is a safe state in a typical excitation system. The remaining logic circuits on the module are fully covered by the system's self-test function, which tests the ability to receive a logic level "0" signal, receive a logic level "1" signal, and crosstalk between inputs within the configured process safety time.

Fail Safe Controller (FSC) was our first generation safety controller and is SIL 3 certified. The FSC system is no longer available for purchase. Contact your local LSS organization representative for migration, spare parts, repair and service.

What Is It?

Fail Safe Controller is a Safety Integrity Level (SIL) certified integrated safety platform. Based on Quadruple Modular Redundant (QMR®) technology, FSC supports a wide range of high integrity process control and safety functions including:

*High-integrity process control

*Burner/boiler management systems

*Process safeguarding and emergency shutdown

*Turbine and compressor safeguarding

*Fire and gas detection systems

*Pipeline monitoring.

FSC provides an easy and reliable integration into Honeywell's TotalPlant Solution system, enabling a powerful integrated safety solution with unified safety, operations and control.

How Does It Work?

FSC provides a dual redundant fault tolerant controller for safety and shutdown applications on the TPS system's Universal Control Network (UCN). These safety functions are integrated into the architecture to support unified operations and control, while at the same time providing the ability to isolate emergency shutdown (ESD) functions from process control strategies on a separate safety network.
By using the tight and reliable integration, FSC shares important features with its UCN peers, enabling direct peer-to-peer communication with Process Managers (PM), Advanced Process Managers (APM), High-Performance Process Managers and Logic Managers (LM). Support of higher level strategies is done through communication with Application Modules and host computers on the Local Control Network.​

What Problems Does It Solve?

Safety solutions based on Honeywell's FSC system can lower the cost of safety and improve plant performance. This is done by reducing the risk of safety incidents, maximizing production uptime, reducing the cost of compliance and providing productivity tools that help users manage safety in their plant.
