The HIMA F3 AIO 8/401 is a compact safety Remote I/O module belonging to the HIMatrix series, manufactured by the German HIMA company. It is specifically designed for high-security industrial automation scenarios and is mainly used to expand the analog input and output capabilities of safety control systems.

The following is the core detailed description of this product:

Product positioning

Series: HIMatrix F3 Series (Compact System).

Main function: As a remote I/O station, it connects to the main controller of HIMA (such as HIMax or HIMatrix controllers) via the safeethernet protocol.

Safety level: Certified by TUV, up to SIL 3 (IEC 61508) and PL e (EN ISO 13849-1).

1. Technical specifications

Detailed specifications of the parameter items

The channel configuration includes 8 analog inputs (AI) and 4 analog outputs (AO).

The signal type analog input supports 4-20mA (configurable). The output is usually 0-20 mA

Working voltage: 24V DC

2. Core functional features

High-security input: The 8-channel analog input is safety-related and specifically designed for monitoring key process indicators such as pressure, temperature, and flow rate.

Controllable output: Although the 4 analog outputs are not directly used as “Safe outputs”, they can be safely Shutdown through user programs.

Remote distributed: It does not run user programs itself and is only responsible for signal collection and forwarding, greatly simplifying on-site wiring.

Zone 2 Certification: Applicable to the installation environment in explosive hazardous areas (Ex-zone 2).

3. Reference for indicator light status

RUN (green): The device is operating normally and data exchange is in progress.

STOP (yellow): The device is in a stopped state or configuration mode.

ERR (red): The system has detected a fault (such as hardware failure, configuration mismatch or communication interruption).

Channel LEDs: Each channel has an independent LED, which is used to indicate the signal status or error code of that point.
