HIMA HIMatrix F2 DO 8 01 Remote I/O Module

Safety regulations and environmental requirements

（1） Core security requirements

Expected use and protective measures

The module is a SELV/PELV safety ultra-low voltage device, which poses no direct danger to itself. For use in Ex areas (such as Zone 2), additional explosion-proof requirements must be met (such as installation in enclosures with protection levels above IP54);

ESD protection: Only personnel with knowledge of electrostatic protection are allowed to operate. ESD wristbands should be worn during work, and when idle, they should be stored in anti-static packaging to avoid static electricity damaging the internal circuits of the module.

Residual risk and emergency response

Residual risk sources: engineering design defects (such as wiring errors), user program vulnerabilities (such as failure to configure fault safety logic), hardware failures (such as relay adhesion), which need to be avoided through compliant configuration and regular testing;

Emergency principle: The module is an integral part of the safety system, and in the event of a malfunction, all outputs must be switched to the "power-off safety state" (such as relay disconnection). It is prohibited to perform operations that obstruct the safe operation of the system in emergency scenarios (such as forcibly activating outputs).

（2） Environment and installation conditions

Specific parameter specifications for the required type

The protection level IP20 (IEC 60529) needs to be installed inside the control cabinet to prevent dust and condensation. Ex Zone 2 requires additional enclosure protection

If the working temperature exceeds 0...+60 ° C, it needs to be downgraded to avoid oxidation of relay contacts and overheating of the circuit

Storage temperature -40...+85 ° C must be met during transportation or idle to avoid component damage

Pollution level II (IEC/EN 61131-2) is applicable to non-conductive dust environments to avoid short circuit risks

Evaluation of heat dissipation and insulation performance is required in high-altitude areas with an altitude of less than 2000 meters

Supply voltage 24 VDC (-15%...+20%) ripple factor ≤ 15%, requires independent power supply (recommended PELV/SELV power supply), equipped with 10A delay fuse

Product Description and Core Features

（1） Basic characteristics of module

Functional positioning and compatibility

Role: As a remote I/O, unable to run user programs independently, requiring SafeEthernet to receive controller instructions and expand the digital output interface of the HIMax/HIMatrix system;

Safety certification: certified by T Ü V, supporting SIL 3（IEC 61508/61511/62061）、Cat. 4（EN 954-1）、PL e（EN ISO 13849-1）， Simultaneously comply with explosion-proof and industrial standards such as ATEX Zone 2 and UL 508;

Model difference: Divided into "F2 DO 8 01 (adapted to ELOP II Factory, part number 98 2200407)" and "F2 DO 8 01 SILworX (adapted to SILworX, part number 98 2200481)", the hardware is the same, only the software adaptation is different.

Core Components and Security Design

Relay output circuit: Each output is equipped with 2 forced guide contact safety relays and 1 standard relay, with a built-in 3.15A fuse (limiting switch current to 60% of rated value, in compliance with VDE 0116), and the contacts support 250 VAC/250 VDC voltage, which can be used for safe shutdown control;

Fault response mechanism: When an output fault is detected (such as relay adhesion or abnormal voltage), only the corresponding output is cut off for a single fault, and all outputs are cut off for an overall module fault. At the same time, the ERROR LED is activated and a fault code is reported;

Self testing function: supports MOT (maintenance testing) and FTT (fault tolerance time) testing, can detect safety switches, relay voltage, temperature thresholds, etc., to ensure output reliability.

Grouping and meaning of LED indicator lights

There are 4 sets of LEDs in the front-end of the module, which perform a full light test when powered on. The status meanings of each indicator light are as follows:

Working voltage light (24 VDC, green): normally on indicates normal power supply, off indicates no voltage;

System lights (red/yellow, multiple lights):

Red light (ERROR): Constant light indicates that the module has entered the ERROR STOP state (such as hardware failure), slow flashing indicates loading the operating system;
