Product Introduction

Basic information
Model: C98043-A7002-L4
Brand: Siemens
Origin: Germany
Siemens Power Board C98043-A7002-L4 is a power board designed for industrial applications, with wide applicability and efficient performance. Its main advantages include:
Logic control module
LOGO series: including LOGO!230RC, 230RCO, 230RCL, 24RC, 24RCL and other models, suitable for various logic control needs.

SITOP DC power supply
Provides DC power supply of various specifications, including 24VDC 1.3A to 20A, and can be used in parallel to meet the power needs of different industrial equipment.

Scope of application
Applicable to a variety of Siemens product series, such as PLC and modules (S7-200, S7-300, S7-400, etc.), inverters (MM420, MM430, etc.) and touch screens (OP27, OP37, etc.).

Product Certification
With 3C certification, the quality and safety of the product are ensured.

Scalability
The C98043-A7002-L4 power board supports expansion and can connect up to 3 racks, which is convenient for system integration and expansion.

Fault diagnosis and processing
A series of fault diagnosis and processing methods are provided to help users quickly locate and solve problems.

Technical parameters
Scalability
Three racks can be expanded. IM360 is inserted in the third slot of the central rack, and IM361 is inserted in the first slot of the expansion rack. The IM361 of the first expansion rack is connected to the IM360 of the central rack, and the IM361 of the remaining racks is connected to the IM361 of the previous rack in sequence. The connection length between racks is 10 meters.

The allowed ambient temperature is:
Vertical installation: 0~40℃
Horizontal installation: 0~60℃1

The CPU and power supply must be installed on the left (horizontal installation) or the bottom (vertical installation).

Function (FC) is the basic module of the program. Most data acquisition, data processing, and data transmission programs* exist in the form of function functions. In essence, these function functions are subroutines that can complete certain functions. Function functions can have formal parameters or no formal parameters.

Error judgment
How to judge power supply or buffer error, such as: battery failure? Address allocation is performed in STEP7.

Analog output template SM332, slot 7: address 304--319; one analog output: 0---10V.

M: ground terminal
L+: 24VDC power terminal
UCM: potential difference between MANA and analog input channel or between analog input channels
UCM common mode voltage, there are two types.

Application scenario
Industrial automation
Applicable to various industrial automation control systems, such as production line automation, robot control, etc.

Energy management
Play an important role in energy management and optimization systems to ensure the stability and efficiency of power supply.

System integration
Easy to integrate with other Siemens products to improve the overall performance and reliability of the system.
