HIMA HIMatrix MI 24 01 Safety Related Controller Module (HI 800 209 E)

HIMA HIMatrix MI 24 01 Safety Related Controller Module (HI 800 209 E)

Product core positioning

MI 24 01 is a modular safety related input module launched by HIMA (Paul Hildebrandt GmbH+Co KG) in Germany, specifically designed for the HIMatrix F60 modular control system. Its core function is to achieve safe acquisition and fault monitoring of 24 analog or digital signals, suitable for scenarios with high safety requirements such as petrochemical, energy, and process industries (such as SIL 3 safety circuits). The module supports software configuration as analog input (0/4~20 mA current signal) or digital input (proximity switch, safety contact, etc.), with safety features such as fault self diagnosis, signal isolation, overcurrent/overvoltage protection, and complies with international safety standards such as IEC 61508 (SIL 3), EN 954-1 (Cat. 4), and EN ISO 13849-1 (PL e).

Key technical specifications

1. Core input capability

Category specific parameters

The number of input channels is 24, which cannot be used as both analog and digital signals at the same time. It needs to be configured independently for a single channel

Analog Input (AI) - Signal Type: 0/4~20 mA Unidirectional Current Signal

-Input resistance: 200 Ω

-Measurement accuracy: ± 0.2% full range at 25 ℃, ± 0.5% full range over full temperature range

-Resolution: 12 bits

-Sampling time: Approximately 45 μ s per channel, refresh rate synchronized with F60 system cycle

Digital Input (DI) - Compatible with EN 60947-5-6 standard proximity switches, safety proximity switches, contacts with resistance wiring

-Nominal input resistance: 674 Ω

-Short circuit current (proximity switch power supply): 12.2 mA

-Response delay: 2 x F60 cycles in L → H direction, H → L direction needs to be combined with filtering configuration

Power output is divided into 3 independent power supply groups (corresponding to channels 1-8, 9-16, 17-24), with a maximum output current of 200 mA per group. It supports switching between 8.2 VDC/26 VDC and has short-circuit protection (restart after 30 seconds of overload, retry after 60 seconds of continuous overload)

2. Physical and environmental parameters

Range of environmental parameter specifications

Working temperature: 0 ℃~+60 ℃ (normal environment inside industrial control cabinet)

Storage temperature -40 ℃~+85 ℃ (for transportation and inventory scenarios)

Protection level module body IP20 (requires overall protection with F60 cabinet, and additional IP54 enclosure for explosion-proof scenarios)

Altitude limit<2000 meters (no need to downgrade)

Pollution Level II (IEC/EN 61131-2, applicable to minor pollution in industrial environments)

Size and Weight - Size: 6 RU height, 4 HP width (compatible with F60 standard rack)

-Weight: 580 g

The power supply requirement is 24 VDC (-15%~+20% fluctuation), provided by the F60 system power module, with a typical power consumption of 5.5 W (no-load) and a maximum power consumption of 16 W (full load)

3. Safety and Compliance

Specific compliance items of certification standards

Functional Safety Standard - IEC 61508: SIL 3 (Safety Integrity Level)

-EN 954-1: Cat. 4 (safety category)

-EN ISO 13849-1: PL e (performance level)

-ATEX/IECEX: Zone 2 hazardous area adaptation (to meet EN 60079-15 enclosure requirements)

Electromagnetic compatibility (EMC) EN 61000-4-2 (electrostatic discharge), EN 61000-4-5 (surge), EN 55022 (radiated emission Class A)

Electrical Safety IEC/EN 61131-2 (Protection Class III) UL 61010-1、CSA C22.2 No. 61010-1

Core functions and fault handling

1. Signal conditioning and safety monitoring

Filtering and anti-interference: Analog input supports software configuration of low-pass filtering (to suppress high-frequency noise), while digital input can enable "noise blanking" (the signal needs to last for 2 system cycles to be recognized to avoid false triggering by surges, but it will increase response delay);

Fault self diagnosis:

Channel level fault: Monitor open circuit (signal<lower limit value), short circuit (signal>upper limit value), abnormal A/D conversion, measurement value exceeding the safe accuracy range. After triggering, set the corresponding error code and light up the ERR light;

Module level faults: power supply abnormality, data bus fault, temperature exceeding limit (FTT test), triggering to cut off power supply to the fault group and report to the system;

Safety response logic: When there is an analog fault, set AI. Error Code>0. When there is a digital fault, output a low level according to the "power loss trip" principle to ensure that the system enters safe mode in the event of a fault.

2. Status indication and operation

LED indicator light status and meaning

RUN (green) constantly on: module power supply is normal; Extinguished: No power supply or module failure

ERR (red) constantly on: module or channel failure; Extinguish: No malfunction

I 1-24 (yellow) constantly on (DI mode): channel activated (powered on); Always on (AI mode): Measurement value reaches the upper limit; Extinguished: Channel not activated or reaching lower limit
