The HIMA F8652E is a Digital Input (DI) Module for the HIMA F86 safety system platform, specifically within the F8650x series family. This module is a certified safety component, not a standard PLC I/O card, designed to read the status of field devices within a Safety Instrumented System (SIS). Its primary function is to interface with safety-critical dry contacts or Namur sensors—such as those from emergency stop buttons, pressure switches, or flame detectors—and convert these physical on/off states into a reliable, diagnosed digital signal for the HIMA safety controller (e.g., an F8650x CPU). It is engineered to meet the rigorous diagnostic and reliability requirements of functional safety standards like IEC 61508. For wiring and safety specifications, the official HIMA F86 Hardware Manual for the F8652E is essential.
The HIMA F3330 984333002, detailed further here, is a high-integrity digital input module from HIMA’s F 35 Safety PLC system. This specialized module is designed to read signals from safety-critical field devices such as emergency stop buttons, safety gates, pressure mats, and gas detectors. Unlike standard PLC input cards, the primary function of the HIMA F3330 is to provide a certified (up to SIL 3 according to IEC 61508), fault-tolerant interface for these signals, ensuring the highest level of reliability for safety instrumented functions (SIF). The module continuously performs self-diagnostics to detect internal faults, cross-circuit faults, and wiring issues. For safety system engineers and maintenance personnel in high-risk industries, the integrity of modules like the HIMA F3330 984333002 is non-negotiable, as they form the essential sensory layer of a safety instrumented system (SIS). Selecting the correct certified components is paramount for achieving and maintaining the required safety integrity level.
The HIMA K9203 is a Central Processing Unit (CPU) / Safety Controller for the HIMA F35 safety system platform. This module is the core computational and logic-solving component of a Safety Instrumented System (SIS), designed to prevent hazardous events and mitigate their consequences in industrial processes. It is not a standard PLC but a specialized, certified device for safety-critical control. The primary function of the K9203 is to execute the application-specific safety logic programmed by the user, continuously monitor input conditions from safety sensors, and—based on its logic—command final elements (like emergency shutdown valves) to bring a process to a safe state. It is engineered and certified to meet the rigorous requirements of international functional safety standards such as IEC 61508 and IEC 61511. For complete safety manuals and certification details, the official HIMA documentation for the K9203 is essential.
Input Voltage: Typically accepts a wide-range AC or DC input, such as 85-264V AC or 88-300V DC, to accommodate various global plant power standards.
Output Voltage: Provides a stabilized and filtered 24V DC output to power the HIQuad backplane and all installed modules.
Output Power/Current: Rated for a specific power output (e.g., 240W, 480W) to support fully populated controller chassis with all modules under load.
Redundancy Support: The HIMA F7126 is designed to be used in redundant (1oo2) configurations. Two modules can be installed in a single chassis, with one actively powering the system and the other in hot standby. Automatic switchover occurs upon failure of the active unit.
Diagnostics & Monitoring: Features comprehensive monitoring of:
Input voltage presence and status.
Output voltage level and stability.
Module temperature.
Load sharing status (in redundant mode).
Failure of the active unit.
Status is communicated via relay contacts (e.g., “Power OK”, “Failure”) and/or over the system backplane to the CPU.
Protection Features: Includes standard protections such as overload protection, short-circuit protection, and overtemperature protection to safeguard both the supply and the downstream controller.
Efficiency & Cooling: High efficiency design to minimize heat generation. May include integrated fans or be convection cooled, depending on the power rating.
Certifications: Certified for use in safety-related systems and complies with relevant EMC and safety standards (e.g., ATEX/IECEx for certain versions).
Form Factor: A slot-in module designed for the HIQuad system chassis.
Number of Channels: Typically 4 or 8 channels per module.
Contact Rating: Typically 2A @ 230V AC or 24V DC, suitable for direct switching of solenoids and small contactors.
Diagnostic Coverage (SFF): High, suitable for Safety Integrity Level (SIL) 3 applications as per IEC 61508.
Key Safety Feature: Incorporates mechanically forced-guided (or “positively driven”) relays. The contacts are mechanically linked so that if a normally-open (NO) contact welds shut, the corresponding normally-closed (NC) diagnostic contact is guaranteed to remain open, allowing the module’s internal circuitry to detect the fault.
Diagnostics: Continuous monitoring for relay coil faults, contact welding (via the forced-guided principle), wire break on the output circuit, and internal module health.
Certifications: Compliant with IEC 61508, IEC 61131-2, and other relevant standards for functional safety.
Module Type: Communication / Interface Module for Safety Systems.
Compatible Systems: Designed for integration with HIMA safety controllers such as those in the HIMax or HIQuad series.
Primary Function: Acts as a protocol gateway and data concentrator. It reads data from the safety controller’s backplane and makes it available to external systems via standard industrial protocols.
Supported Communication Protocols: Commonly supports widely used protocols for integration, which may include:
Modbus TCP/IP (for Ethernet-based SCADA, DCS, and HMI connectivity).
Modbus RTU (for serial communication).
OPC (DA/UA) for connection to historians and advanced visualization systems.
HIMA’s proprietary protocols for peer-to-peer communication between safety systems.
Data Mapping: Allows configuration of data points (process values, diagnostics, system status) from the safety controller to be mapped to registers or tags in the external protocol.
Interface Ports: Typically features physical ports such as RJ45 Ethernet and/or serial ports (RS-232/485).
Safety Integrity: While not executing safety logic itself, the module is designed for use in safety systems. It operates in the non-safety domain but is built to high reliability standards to ensure communication availability without affecting the safe operation of the controller.
Diagnostics: Includes self-diagnostic capabilities and status indicators (LEDs) to monitor communication link health and module operation.
Configuration: Configured using HIMA’s engineering software suite (e.g., Safety-Editor or dedicated configurators).

Diagnostics: Includes continuous monitoring for wire breaks, short-circuits to ground/power, cross-channel faults, and internal module faults.
Safe State Definition: Configurable per channel for fault behavior (e.g., can be set to 0 or 1 in case of a detected fault).
Certifications: Compliant with major international standards including IEC 61508, IEC 61131-2, and ATEX for use in hazardous areas (with appropriate barriers).

The HIMax system achieves high safety through advanced diagnostics rather than hardware redundancy at the CPU level, though the system supports redundant CPU configurations for higher availability.
Processor & Performance: Features a powerful microprocessor optimized for deterministic execution of safety logic. It provides predictable scan times suitable for fast-acting safety functions.
Memory: Equipped with fault-secure memory (RAM and Flash) with error detection and correction (ECC). The memory stores the safety application, operating system, and configuration data.
