Product Details Introduction

Siemens 6DD1681-0CA2 SITOR Interface Module

Siemens 6DD1681-0CA2 is a specialized SITOR interface module for SIMADYN D systems, following the SE20.2 specification. It is used for high-speed, isolated communication between SIMADYN D and SITOR converter systems and is a key interface component for transmission closed-loop control.

Belonging to the SIMADYN D series, it is a SE20.2 interface module specifically designed for SITOR converters.

Implement RS-485 differential communication between SIMADYN D and SITOR inverter systems.

Support direct coupling installation of interfaces such as PG16, PG26, PT20G, etc.

Equipped with 6 dual color LED indicator lights, real-time display of communication and operation status.

Equipped with power failure relay output, it can quickly alert in case of abnormalities.

The electrical interface includes multiple protections such as 4000V lightning protection, 1.5A overcurrent, and 600W surge protection.

Supports DC9-36V wide voltage input and is compatible with 24V industrial standard power supply.

Provide DC1500V electrical isolation to enhance signal anti-interference and safety.

Support reverse connection protection to reduce the risk of damage caused by wiring errors.

Installed on a 35mm standard guide rail, it is easy to integrate and saves space.

Weighing only 0.6kg, the structure is compact and suitable for small cabinet spaces.

The communication rate can be manually set or adaptively adjusted through a dip switch.

Made in Germany, certified by CE, with high industrial reliability.

The product has been discontinued, and the market mainly consists of original spare parts and second-hand/refurbished parts.

Widely used in closed-loop control scenarios such as steel rolling, metallurgy, and high-power transmission.

In summary, 6DD1681-0CA2, with its SE20.2 standard interface, strong isolation protection, and comprehensive status monitoring, has become a reliable bridge for communication between SIMADYN D and SITOR converters, and is the core choice for maintenance and spare parts replacement of old high-power transmission systems.
