Siemens SIMOCODE pro 3UF7 System Main Component Model Overview

SIMOCODE pro 3UF7 is a flexible, modular low-voltage motor management and control device launched by Siemens. It is designed to provide comprehensive protection, monitoring, control, and communication functions for fixed-speed motors.

A core feature of this system is its modular design. Depending on the motor's power and control requirements, you can build a customized motor management solution like assembling building blocks, starting from a core basic unit and then optionally adding current/voltage measuring modules and various expansion modules as needed.

SIMOCODE pro 3UF7 System Main Component Model Overview

To help you quickly understand the full range of products, I have organized the models of the main components as follows:

1. Basic Units

These are the core of the system, responsible for control logic and communication. Based on the functional level and communication protocol, there are several main series:

Series Communication Protocol Order No. Example Key Features & Description

SIMOCODE pro C PROFIBUS DP 3UF7000-1AB00-0 Economical version, suitable for basic applications like direct starting, reversing starting, etc.

SIMOCODE pro V PROFIBUS DP 3UF7010-1AU00-0 Full-featured version, supports all control functions, expandable, can measure voltage and power.

SIMOCODE pro V MODBUS RTU 3UF7012-1AB00-0 pro V version with MODBUS RTU communication interface.

SIMOCODE pro V PROFINET IO 3UF7013-1AB00-0 pro V version with PROFINET interface, supports OPC UA server functionality, currently the mainstream choice.

SIMOCODE pro S - 3UF7... Features between pro C and pro V, supports complex starting methods like star-delta.

All basic units come standard with 4 digital inputs and 3 relay outputs, and integrate a PTC thermistor interface.

2. Current/Voltage Measuring Modules

These modules are used to connect to the main circuit and acquire current and voltage signals. They must be used in conjunction with a basic unit.

Current Setting Range Width Connection Method Order No. Example

0.3 ... 4 A 45 mm Feed-through (Aperture 7.5 mm) 3UF7110-1AA01-0

2.4 ... 25 A 55 mm Feed-through 3UF7111-1AA01-0

10 ... 100 A 120 mm Busbar connection 3UF7112-1AA01-0

20 ... 200 A 120 mm Busbar connection 3UF7113-1AA01-0

63 ... 630 A 145 mm Busbar connection 3UF7114-1BA01-0

Special Note: For motors above 630A, the measuring range can be extended by using external current transformers (e.g., 3UF1868-3GA00), allowing monitoring up to approximately 820A.

3. Expansion Modules

When the I/O points of the basic unit are insufficient or special functions are required, up to 5 expansion modules can be connected (total cable length not exceeding 3 meters).

Module Type Function Description Order No. Example

Digital Module (DM) Adds 4 digital inputs and 2 relay outputs 3UF7210-1AA00-0

Analog Module (AM) Adds 2 analog inputs and 1 analog output 3UF7410-1AA00-0

Ground Fault Module (EM) Used in conjunction with 3UL22 summation current transformers for high-precision ground fault detection 3UF7510-1AA00-0

Temperature Module (TM) Used to connect temperature sensors like Pt100, KTY for precise motor temperature monitoring 3UF7610-1AA00-0

4. Operator Panels and Accessories

To facilitate commissioning and on-site operation, operator panels and various accessories can also be selected.

Category Name/Function Order No. Example

Operator Panel For local control, parameter setting, and data display 3UF7900-0AA00-0

Connection Cable Used to connect various modules, available in various lengths (0.025m, 0.1m, 0.3m, 0.5m, 1.0m, 2.5m) 3UF7910-0AA00-0 (0.1m)

Decoupling Module Must be used for voltage measurement in non-grounded systems (e.g., IT systems) 3UF7150-1AA00-0
