The F 3236 (also designated as F3226 / F 3226) is a 16-fold safety-related digital input interface card engineered by HIMA for discrete signal processing within the Planar F automation structure. This module interfaces discrete field instrumentation, sensors, or switches with safety-critical automation hardware loops to capture binary state statuses. Designed for high-integrity plant networks, it evaluates 1-signal currents or mechanical contact interfaces while operating with comprehensive, automatic background hardware diagnostics to verify signal line boundaries. The module executes periodic diagnostics, including active sensor loop monitoring and filtering component reviews, ensuring dependable state verification for emergency shutdown and functional protection architectures.
Features
Processes 16 separate discrete input sensor or contact lines simultaneously.
Performs continuous automatic self-tests covering cross-talking via walking-zero routines during live operations.
Validates internal filter capacitor health and complete logic card circuit operation transparently.
Features integrated safety isolation boundaries to ensure safe channel performance within high-demand plant logic systems.
Applications
High-integrity digital input processing for mechanical switches and binary field sensors.
Safety-isolated contact status monitoring inside critical process emergency shutdown environments.
Continuous instrumentation logic interfacing within standard architectural safety control chassis configurations.
