ALSTOM | SPU232 | Logic Operation Module | SPU232

The core function is to perform logical processing on the input signal (such as AND, OR, NOT, XOR, etc.) and output control signals to achieve linkage between devices or system protection. It supports basic logic gates (AND, OR, NOT, XOR) and complex combinational logic, and can realize extended functions such as timer, counter, comparator, etc. It has built-in timers (such as TON, TOF) and counters (CTU, CTD) for delay control or event counting.

　　ALSTOM is a world-leading manufacturer of rail transit, power and energy equipment. Its industrial control products are known for their high reliability, strong adaptability and long life. The SPU232 module belongs to ALSTOM's industrial control product line and is widely used in rail transit signal systems, power automation and other fields.

　　Module positioning

　　SPU232 is a logic operation module. The core function is to perform logical processing on input signals (such as AND, OR, NOT, XOR, etc.) and output control signals to achieve linkage between devices or system protection.

　　Core functions

　　Logical operation capability

　　Supports basic logic gates (AND, OR, NOT, XOR) and complex combinational logic.

　　Extended functions such as timers, counters, and comparators can be realized.

　　Supports sequential control logic (such as ladder diagram programming).

　　Signal processing

　　Input signal type: digital quantity (switch quantity), analog quantity (need to cooperate with conversion module).

　　Output signal type: relay contact, transistor switch, analog signal (such as 4-20mA).

　　Signal isolation: The input/output end usually has photoelectric isolation to improve anti-interference ability.

　　Communication interface

　　Supports serial communication (such as RS232, RS485), and can exchange data with the host computer or PLC.

　　Some models integrate fieldbus interfaces (such as Modbus, Profibus) for easy system integration.

　　Self-diagnosis and protection

　　Real-time monitoring of input/output status, triggering alarm or safety mode in case of failure.

　　Overvoltage, overcurrent, and short-circuit protection to ensure stable operation of the module.

　　Timing and counting functions

　　Built-in timers (such as TON, TOF) and counters (CTU, CTD) for delay control or event counting.

　　Application scenarios

　　Railway transit signal system

　　Control turnout switching, signal light display, and train route logic.

　　For example: when the track occupancy signal (input) is detected, the turnout lock (output) is triggered through logical operation.

　　Electric power automation

　　Realize circuit breaker opening and closing control and protection device linkage.

　　For example: overcurrent protection logic: when the current exceeds the threshold (input) and the duration reaches the standard (timer), the circuit breaker tripping (output) is triggered.

　　Industrial automation production line

　　Control equipment start and stop, material sorting, and safety door interlocking.

　　For example: when the emergency stop button is pressed (input), all motors are stopped immediately (output).

　　Building intelligence

　　Lighting control, air conditioning system linkage, fire alarm processing.

　　ALSTOM SPU232 logic operation module has become a classic choice in the field of rail transit and industrial control with its high reliability, strong logic processing capability and wide applicability. When selecting, it is necessary to combine input/output requirements, environmental conditions and communication protocols. Daily maintenance should focus on status monitoring and spare parts management.

　　Advantages and features

　　High reliability: using industrial-grade components, passing EMC tests, and adapting to harsh electromagnetic environments.

　　Modular design: supports hot plugging, easy maintenance and expansion.

　　Programming flexibility: can be programmed through IEC 61131-3 standard languages such as ladder logic and function block diagram (FBD).

　　Compatibility: can be seamlessly integrated with other ALSTOM series modules (such as analog input/output, temperature control module).
