HIMA F6251 safety-related limit monitor

Overview

HIMA F6251 as a 0/4–20 mA safety-related limit monitor designed for applications requiring Requirement Class 6 (RC 6) safety performance. It is intended for monitoring analog process signals and generating switching actions when configured threshold values are exceeded or undershot.

Specifications

Function

Limit monitors (also with safety-related design) are used for monitoring analog signals to see whether the signals exceed or fall below the adjusted limit value.

System Characteristics

The HIMA F6251 is part of the HIMA Planar-System F, a modular electronic control platform developed for process automation and safety applications. The system features:

l 24 V DC operating voltage

l Modular Eurocard design

l High-reliability electronic components

l Typical Mean Time Between Failures (MTBF) of approximately 200 years

l Safety-related modules designed to ensure outputs automatically transition to a de-energized safe state in the event of internal faults.
