HIMA F3236

Description

Product Overview and Description

The HIMA F3236 is a vital component within HIMA’s safety automation portfolio, specifically serving as a power supply and system interface module for their modular F35 programmable safety system. This module is a foundational element, providing regulated and monitored power to the central processing unit (CPU) and all other I/O modules within a local F35 rack. More than just a power converter, the HIMA F3236 acts as the primary communication gateway between the local safety rack and the higher-level plant control network (e.g., via PROFIBUS DP or Modbus) and/or other HIMA safety systems via the proprietary HIMatrix bus. Its role is critical for ensuring the integrity and availability of the entire safety controller. The design of the HIMA F3236 emphasizes fault-detection and diagnostic capabilities, monitoring its own status and the health of the supplied power, which are essential for maintaining the required Safety Integrity Level (SIL) of the safety instrumented functions (SIFs). Proper selection and configuration of the HIMA F3236 is therefore a fundamental step in engineering a reliable and compliant safety system.

Product Parameters and Specifications

• Product Type: Safety System Power Supply and Communication Interface Module

• Manufacturer Part Number (MPN): F3236

• Brand: HIMA

• System Compatibility: HIMA F35 Programmable Safety System.

• Primary Functions:

  1. Power Supply: Converts an external AC or DC input voltage (e.g., 24V DC, 115/230V AC) to the stabilized system voltage required by the F35 backplane and modules.

  2. Communication Interface: Typically provides one or more ports for PROFIBUS DP-V1, enabling safety communication (PROFIsafe) and/or standard data exchange with a DCS or PLC.

  3. System Bus Interface: Connects to the HIMatrix bus for inter-controller communication and system expansion.

• Input Voltage: Range specified by variant (e.g., 24V DC, 85-264V AC).

• Output Power: Rated wattage/amperage to supply a fully populated F35 rack. Must be calculated based on the total load of all modules.

• Safety Certification: Integral part of the F35 system’s overall SIL 3 certification (IEC 61508).

• Status Indicators: Comprehensive LEDs for power status (Input/Output), communication activity (PROFIBUS, HIMatrix), and fault conditions.

• Mounting: Designed to be installed in the left-most slot (Slot 1) of an F35 baseplate/rack.

Key Advantages and Features

The HIMA F3236 offers significant advantages by integrating power and communication into a single, safety-approved module, saving space and simplifying system architecture. Its built-in diagnostics monitor for undervoltage, overvoltage, and overtemperature conditions, providing early warning of potential power-related failures that could compromise safety availability. The module supports redundant power supply configurations to achieve higher availability targets. A key feature is its certified PROFIBUS DP-V1 interface with PROFIsafe protocol support, allowing for seamless and safe integration into a wide range of automation landscapes from Siemens, ABB, and others. The robust design of the HIMA F3236 ensures stable operation in industrially demanding environments with electrical noise and temperature fluctuations. Its clear diagnostic indicators enable rapid fault localization, which is crucial for minimizing system downtime during maintenance.

Application Scenarios and Use Cases

The HIMA F3236 is deployed as the core interface module in F35 safety controllers used across high-hazard industries. A primary application is in oil and gas pipeline stations, where an F35 system using the HIMA F3236 as its main interface provides Emergency Shutdown (ESD) and Fire & Gas (F&G) control, communicating process alarms and status to the main station DCS via PROFIBUS. In chemical batch processes, it forms the heart of a reactor safety interlock system, receiving commands from the batch PLC and sending trip signals to final elements. For burner management systems (BMS) on industrial boilers, the HIMA F3236 facilitates communication between the safety logic and the plant’s distributed control system. It is also commonly used in modular machine safety, where a central F35 controller, powered and networked via the HIMA F3236, coordinates multiple safety zones and exchanges data with the standard machine PLC.

Comparison with Competing Products

Compared to a standard PLC power supply or communication coupler, the HIMA F3236 is fundamentally different due to its integral safety certification as part of a dedicated Safety Instrumented System (SIS). Competing products would be the power/communication interface modules from other SIS manufacturers, such as the Siemens ET200proF IM 154-3F PN interface module or the Rockwell GuardLogix with a communication adapter. The HIMA F3236 differentiates itself through HIMA’s focus on TÜV-certified, independent safety systems. Compared to integrated safety solutions, the F35 platform with the HIMA F3236 offers a physically and logically separated safety controller, which is often a requirement for high-SIL applications in process industries. Its combination of power distribution and high-performance safety communication in one module provides a compact and optimized solution.

Selection Guidelines and Important Notes

Selection Advice:

1. Calculate Power Budget: Before selecting the HIMA F3236, you must calculate the total power consumption of all intended F35 modules (CPU, I/O) in the rack to ensure the power supply’s capacity is not exceeded.

2. Define Communication Needs: Confirm the required network protocol (e.g., PROFIBUS DP, PROFINET depending on variant). The HIMA F3236 must match the network architecture of the supervising control system.

3. Verify Input Voltage: Select the correct variant of the HIMA F3236 that matches your plant’s available supply voltage (e.g., 24V DC or 120V AC).

4. Plan for Redundancy: For high-availability applications, design a redundant power supply configuration from the outset, which may require specific wiring and an additional module.

Important Precautions:

• Mandatory Position: The HIMA F3236 must be installed in Slot 1 of the F35 baseplate. Incorrect placement will prevent the system from starting.

• Safety System Procedures: All work must be performed by personnel trained on HIMA safety systems and in accordance with the site’s safety work procedures.

• Use Official Documentation: Always follow the installation and wiring diagrams in the official HIMA F35 manual for the F3236.

• Grounding and Shielding: Proper functional grounding and communication cable shielding are critical for noise immunity and safe operation. Follow EMC guidelines strictly.

• Certification Maintenance: Any modification to the system hardware, including replacing the HIMA F3236, may impact the overall safety loop certification. Keep detailed records and validate the system after changes.

• Testing: Include the functionality of the HIMA F3236 (power monitoring, communication link) in the regular proof testing schedule for the safety system.
