Main Functions

Electro‑pneumatic pressure conversion: Convert electronic braking commands from locomotive control system into precise pneumatic output pressure for brake cylinders and train brake pipe; perform charging, holding and venting of compressed air according to brake demand.
Service brake & emergency brake execution: Realize normal service braking, release and emergency brake trigger; support both electronic brake mode and fallback pure‑pneumatic backup mode when electronic circuit fails, satisfying safety redundancy requirements EN5012x SIL certification.

MB04B – MaxControl Series Modular Electro‑Pneumatic Brake Control Module

Load‑dependent pressure adjustment: Automatically correct brake cylinder pressure based on vehicle load weight to avoid over‑braking or insufficient braking force.
Diagnostic & status feedback: Collect internal pressure sensor signals, report module fault codes and working status to locomotive vehicle bus for on‑board diagnosis and condition‑based maintenance.
Brake pipe management: Control charging and decompression of train brake pipe for hauled freight/passenger carriages, compatible with UIC and Chinese railway TJ/JW‑100 brake standards.

MB04B – MaxControl Series Modular Electro‑Pneumatic Brake Control Module

Primary Application: Main‑line diesel‑electric & electric locomotives; it is a key component of MaxControl brake rack, widely applied on Chinese domestic and export locomotives.
System Position: As a modular LRU unit inside MaxControl brake cabinet, it undertakes core pneumatic control tasks, cooperating with other MB‑series modules to complete full locomotive brake logic.

MB04B – MaxControl Series Modular Electro‑Pneumatic Brake Control Module

Operational Purpose: Govern service brake, emergency brake, train pipe control for locomotive and coupled wagons; guarantee stable, repeatable braking performance under heavy‑haul freight and passenger transport conditions. Modular LRU design enables quick on‑site replacement, short maintenance downtime and lower life‑cycle cost.More products: www.plcva.com
Compatibility: Works with locomotive TCMS, supports communication via vehicle control bus; provides pneumatic backup path to ensure basic brake function remains available upon electronic failure.
