Alstom BCSR1 TERMINAL BOARD OF 8 LOGIC OUTPUT SIGNALS

Product Overview

The Alstom BCSR1 terminal board is an 8-channel logic output signal conversion and drive adaptation core component designed by Alstom specifically for industrial automation control systems. Its core function is to provide safe conversion, load adaptation, and stable drive transmission for logic control signals output by upper level controllers (such as PLC/DCS). This terminal board serves as a key signal bridge between the control system and the on-site execution mechanism, capable of centralized conversion and standardized wiring of 8 discrete logic output signals. Through standardized terminal interfaces, it achieves precise docking with various execution components (such as relays, contactors, solenoid valves). At the same time, it has core features such as output short-circuit protection, reverse connection protection, and enhanced anti-interference, ensuring the reliability of logic output signal transmission and the safe operation of the execution mechanism. It adopts industrial grade high load terminals and reinforced insulation design, with a compact structure and easy installation. It is widely integrated into the execution end of automation control scenarios such as industrial manufacturing, rail transit, and energy monitoring, providing a basic guarantee for the orderly output of system logic control signals and the precise driving of execution mechanisms.

Working principle

The core of Alstom BCSR1 terminal board is based on the working logic of "logic signal centralized conversion load adaptation safe drive transmission". As a pure passive signal conversion and drive adaptation component, it does not have signal processing function. Its core function is to build a reliable control link between the upper controller and the on-site execution mechanism. By strengthening protection, channel isolation, and standardizing terminal interface design, it ensures the safe transmission of logic output signals and precise driving of the execution mechanism.

The specific workflow is as follows: Firstly, the 8-channel logic control signals of the digital output module of the upper controller (such as PLC/DCS) are connected to the 8-channel independent output terminals of the terminal board through cables. According to the controller output type (PNP/NPN), they are connected to the dedicated common terminal. At the same time, they are connected to the DC 18-30V external power supply through the power adapter terminal to provide power support for the actuator drive; The terminal board independently transfers each output signal through internal reinforced insulation isolation lines to avoid crosstalk between signals from different channels. At the same time, real-time monitoring of each output is carried out through built-in protection circuits; Subsequently, the standardized output terminals and connecting cables are used to synchronously transmit the organized 8-channel logic output signals to the on-site execution mechanism (such as relay coils, solenoid valves, contactor coils, etc.), completing the transfer of control signals and the driving of the execution mechanism; Throughout the entire signal transmission and driving process, the high-level insulation structure, channel isolation design, and high load terminals of the terminal board continue to function, ensuring stable transmission of logic control signals in harsh industrial environments. At the same time, the built-in short-circuit protection and reverse connection protection circuits respond to fault states in real time, quickly cutting off the circuit when a load short circuit or power supply reverse connection is detected, protecting the safety of the controller and terminal board; The standardized terminal layout facilitates signal identification, wiring inspection, and troubleshooting for operation and maintenance personnel, improving system operation and maintenance efficiency.
