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).
System Compatibility: HIMA F3x Series I/O System, compatible with HIMA safety controllers like HIQuad X, HIMax, etc.
Function: Digital Input Module for Safety Applications.
Number of Channels: Typically 8 or 16 channels per module (varies by specific sub-variant).
Input Type: Configurable for NAMUR sensors (IEC 60947-5-6) or dry contact (volt-free) signals.
Diagnostic Coverage (SFF): High (>90%), supporting use in Safety Integrity Level (SIL) 3 applications as per IEC 61508.
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).
