BLASI – PLC control module Siemens
BLASI – PLC control module Siemens (Article No: 8400041) is a factory‑packaged control unit for BLASI automatic‑door or barrier systems that uses a Siemens‑brand PLC core (typically S7‑1200 or similar) as the main logic brain. It integrates a Siemens CPU, power supply, and relevant I/O into a compact BLASI‑style cabinet or DIN‑rail sub‑rack, pre‑configured with BLASI‑specific firmware for door sequences, safety interlocks, and drive control. The 8400041 article number identifies this exact Siemens‑based PLC module variant within BLASI’s spare‑parts catalog.
Product Details
The BLASI – PLC control module Siemens 8400041 is essentially a Siemens PLC set up and branded by BLASI for automatic‑door or barrier applications. It usually contains a Siemens S7‑1200‑type CPU with integrated 24 V DC power, onboard digital inputs and outputs, and Ethernet or PROFINET for communication with other BLASI units (such as SAIA controllers, TA boards, or frequency inverters). The module runs BLASI‑specific PLC programs that manage door‑open/close logic, edge‑sensor and light‑curtain safety, access‑control inputs, and feedback signals while logging faults and runtime data for diagnostics.
In BLASI installations the 8400041 module commonly acts either as the central controller or as a subordinate station in a more complex scheme, connected via Siemens fieldbus or Ethernet to higher‑level building‑management or security systems. BLASI supplies this module with a pre‑loaded configuration, so on‑site work is mainly limited to adjusting timing parameters and safety thresholds rather than writing full PLC code. By using the BLASI – PLC control module Siemens (Article No: 8400041), BLASI provides a robust, upgradable, and Siemens‑compatible control “core” that keeps automatic‑door and barrier logic centralized, maintainable, and easy to integrate with standard Siemens programming and monitoring tools.
