Introduction
The HIMA F 3105 Relay Output Module is a safety automation component designed for the HIMA Planar F control platform. It allows the safety controller to activate external equipment through relay-based switching outputs. Each of the four channels operates independently, enabling the module to control multiple safety devices simultaneously.
In industrial facilities where hazardous processes are present, safety instrumented systems must respond quickly to abnormal conditions. The F 3105 module provides a reliable interface between the safety controller and field devices responsible for executing protective actions.
Because of its robust design and compatibility with HIMA safety architectures, the module is widely used in industries that require high-integrity safety control, including petrochemical processing, energy production, and industrial manufacturing.

Safety-Critical Control Applications
The HIMA F 3105 Relay Output Module is designed for safety-related automation systems within the HIMA Planar F architecture. Relay output modules play an important role in safety instrumented systems (SIS), where they provide secure switching functions to control external devices such as alarms, actuators, and shutdown mechanisms.
The F 3105 module offers four independent relay channels that allow the control system to send discrete output signals to field equipment. These outputs are typically used to activate safety responses, initiate alarms, or control critical plant equipment when specific process conditions are detected.
Typical industrial applications include:
-
Safety instrumented systems in chemical processing plants
-
Emergency shutdown systems in oil and gas facilities
-
Industrial alarm activation circuits
-
Control of safety-related actuators and valves
-
Power generation safety control systems
-
Hazardous process monitoring environments
By providing reliable relay switching capability, the module enables the automation system to execute critical safety actions when required.
