1. System Overview: HIMatrix F35 Compact Safety Controller
HIMatrix F35 is a compact controller designed specifically for industrial automation safety applications. The device is integrated into a metal casing and provides comprehensive I/O interfaces, enabling SIL 3 level safety functions without the need for complex modular cabinets.
Core configuration and authentication:
Safety level: Certified by T Ü V, compliant with IEC 61508 SIL 3, IEC 61511, and IEC 62061 standards.
Performance level: Complies with EN 954-1 Cat. 4 and EN ISO 13849-1 PL e standards.
Explosion proof certification: applicable to Zone 2 (ATEX) explosion-proof area.
Certification bodies: T Ü V, UL, FM approvals, Lloyd's Register, etc.
Main I/O scale:
24 digital inputs (DI): Supports mechanical contact or signal source connections.
8 digital outputs (DO): Supports direct load driving and has overload protection.
2 counters: supports multiple modes (counting, Gray code decoding).
8 analog inputs (AI): supports voltage (0-10V) and current (0-20mA) measurement.
2. Security architecture and functional design
The safety design of F35 controller is based on the principles of "de excitation trip" and "live trip". This means that in the event of a malfunction, the system will automatically enter a defined safe state (usually a de excitation state).
2.1 Safety Related Digital Input (DI)
Signal processing: Input signals are collected as analog measurement values and converted to Boolean values through configurable thresholds. The default setting is: low level<7V, high level>13V.
Line monitoring: Although the digital input of F35 itself does not require line monitoring, an open circuit is considered a safe (low level) state.
Power supply: For mechanical contacts without independent power supply, the controller provides a 24V power supply (LS+) with short-circuit protection internally.
2.2 Safety Related Digital Output (DO)
Fault response: If an output fault (such as a short circuit) is detected, the affected output channel will immediately switch to a safe (de excitation) state through a safety switch.
Overload protection: If an overload occurs, the affected output or all outputs will be turned off and automatically restored after troubleshooting.
Line monitoring support: The analog input of F35 can be used to monitor the open and short circuits of digital outputs, thereby achieving SIL 3 compliant line integrity monitoring.
2.3 Safety related counters
Resolution: 24 bit resolution, maximum count value is
2 24−1=16,777,2152
pattern
Counting function 1: Depending on the counting direction input signal, it supports up/down counting.
Counting function 2: It is independent of the input signal in the counting direction and is controlled by the program to add/subtract.
Decoding operation: used to connect the absolute value rotary encoder (3-bit Gray code).
2.4 Safety related Analog Input (AI)
Measurement range: 0... 10 V DC or 0... 20 mA (via shunt resistor).
Accuracy: The safety related accuracy is ± 2% (final value).
Safety principle: The input signal is evaluated according to the principle of de excitation tripping.
