Product Introduction

Siemens Robincon A1A252241.155S is an expansion communication board designed for Siemens Robincon inverters. The main function of this communication board is to expand the communication protocol of the inverter so that it can support more network communication requirements.

Universal power phase: three-phase

Rated voltage: three-phase AC525-690V

Adaptive motor power: up to 6000kW

Power supply voltage: high voltage filter without filter

DC power nature: current type

Control mode: current vector

High precision: ensure accurate transmission of communication data.

Dimensions: 28011010mm, easy to install and maintain.

The expansion communication board is installed on the serial communication board: it plays the role of expanding the communication protocol. Each NXGpro control system has two communication interfaces to realize network communication through various communication protocols.

Inverter preventive maintenance (PMA)
Inverter preventive maintenance (PMA) is the main measure to improve the reliability of the inverter, reduce maintenance and repair costs, extend the service life of the inverter, and reduce unexpected downtime. Its main measures include checking the current problems of the inverter and eliminating the hidden dangers of safe operation, thereby improving the operating performance of the inverter, reducing the failure rate, reducing downtime, and improving equipment utilization.

Application scenarios
A1A252241.155S communication board is widely used in a variety of industrial automation scenarios, including but not limited to:
Production line transformation: By upgrading communication capabilities, the automation level of the production line is improved.
Power generation: Ensure the stability and reliability of power supply.
Water/wastewater treatment: Achieve high output at low power and optimize water treatment efficiency.
Oil and gas: Small footprint, high availability, suitable for field operations.

Role in Siemens Robincon inverter
As an extended communication board: A1A252241.155S is a spare part of Siemens Robincon inverter, which is an extended communication board. It is installed on the serial communication board and plays the role of expanding the communication protocol. This helps the inverter to achieve network communication through various communication protocols, so as to better perform data interaction and other operations with other devices.

Relevant role in Siemens equipment system
Related to various Siemens equipment:
In terms of Siemens Robincon spare parts, it is related to A1A, A5E, LDZ, 6SR, etc. In Siemens controllers, it is related to 6DD1, 6DD2, 3154OP, 6DP, etc. In terms of Siemens S120, it is related to A5E, 6SL30, 6SL31, etc. It is also related to Siemens DC speed regulation (6RA80, 7VV, 6RY, 6RX, etc.), Siemens servo CNC (1FK, 1FT, 1PH, 1FN, 1FW, 6FC, 6FX, 6SN, 6AU, etc.), Siemens MASTERDRIVE (6SE70, 6SY70, etc.), Siemens vacuum circuit breaker/contactor (3AH, 3AE, 3TL, 3TM, VS30, 3AY, 3AX, etc.), Siemens conventional motor (1PQ, 1LA, 1LL , 1LE, 1LG, etc.), Siemens instruments (6GT, 6DR, 7MB, 7ME, 7MF, 7MH, 7ML, etc.), Siemens LCI/Robincon and medium voltage spare parts (6SL39, 6SB, 6SC, 6SD, 6ZY, etc.) and Siemens integrated protection (6SJ, 7PA, 7UM/UT, 7KG, 7RW, 7VE/VH, 7XT/XV, etc.), which reflects its importance and relevance in the entire Siemens equipment system.

Improving the performance of Siemens Robincon inverters
Assisting in inverter preventive maintenance: inverter preventive maintenance (PMA) is essential for improving inverter reliability, reducing maintenance and repair costs, extending service life, and reducing unexpected downtime. Although it is not explicitly stated that A1A252241.155S is directly involved in preventive maintenance, as a component of the inverter, its normal operation helps the entire inverter system remain stable, thereby indirectly having a positive impact on the inverter's preventive maintenance goals. For example, ensuring normal communication is conducive to timely obtaining the operating status information of the inverter, which is convenient for preventive maintenance measures, such as checking the current problems of the inverter and eliminating hidden dangers in safe operation, thereby improving and enhancing the operating performance of the inverter, reducing the failure rate, reducing downtime, and improving equipment utilization.
