HIMA K9202 996920202

Description

Product Overview

The HIMA K9202 996920202 is a vital safety module from HIMA’s renowned HIMatrix safety system, specifically designed as a Solenoid Driver Output Module. Its primary function is to reliably control safety-critical final elements, such as solenoid valves or motor contactors, in demanding safety instrumented systems (SIS). Engineered with fault-tolerant architecture, the HIMA K9202 ensures that safety shutdown functions are executed with the highest degree of integrity, making it a cornerstone component for process safety in high-hazard industries.

Advantages and Core Features

The HIMA K9202 996920202 offers unmatched reliability for safety-critical outputs. Its key advantage is the integrated, comprehensive diagnostic coverage that continuously monitors the health of the module itself, the wiring, and the connected load. This proactive fault detection is essential for maintaining the required Safety Integrity Level (SIL). Designed for the HIMatrix system, the K9202 benefits from a fully redundant and fault-tolerant bus architecture, ensuring communication integrity. Its robust design minimizes the risk of dangerous undetected failures, which is the primary mandate for any safety system component.

Application Scenarios

This module is deployed in industries where process failure could have catastrophic consequences:

• Oil & Gas: Controlling emergency shutdown (ESD) valves on offshore platforms, pipelines, or refinery units.

• Chemical/Petrochemical: Actuating final elements for reactor overpressure protection or fire & gas systems.

• Power Generation: Operating critical fuel shut-off valves or turbine trip mechanisms.

• Pharmaceutical: Managing safety interlocks on high-pressure or high-temperature reaction vessels.

Comparison with Competing Products

Compared to standard PLC output modules or even basic safety relays, the HIMA K9202 is in a different class, designed specifically for high-performance, certified SIS applications. While competitors like Siemens (SIMATIC S7 F/FH) or Rockwell (GuardLogix) offer safety I/O, HIMA’s dedicated safety system architecture, exemplified by modules like the K9202, often provides superior diagnostic coverage, simpler safety validation, and a hardware design focused exclusively on safety (no compromise for standard control). This makes it the preferred choice for the most critical layers of protection.

Selection Guide and Important Notes

Selecting the HIMA K9202 996920202 is part of designing a complete HIMatrix safety system. It must be specified by a certified safety engineer as part of a Safety Instrumented Function (SIF) loop with a defined SIL target.

Important Precautions:

• Safety System Integration: This module cannot function as a standalone device. It requires a HIMatrix central controller and proper system configuration.

• Certified Engineering: Implementation must follow HIMA’s guidelines and should be performed by personnel trained in functional safety.

• Load Compatibility: The connected solenoid or load must be compatible with the module’s electrical specifications (voltage, current, inductance).

• Proof Test Interval: The overall SIF, including the HIMA K9202 module, will have a required proof test interval defined during the design phase that must be adhered to.
