Product introduction

The Siemens 3TK28 is a safety relay module or multifunctional device in the SIRI

The Siemens 3TK28 is a safety relay module or multifunctional device in the SIRIUS series, primarily used to implement safety-related functions and suitable for a variety of industrial scenarios. The following is a detailed description: - **Product Function**: It can be used for safety-related functions such as emergency stop monitoring and protective door monitoring. It can also be used to monitor non-contact protective equipment such as light curtains and safety mats. It is often used in machinery with moving parts. - **Model Classification and Features**: Taking the 3TK2845 as an example, this model has two versions. One is Stop Category 0, with all outputs shutting down without delay; the other is Stop Category 0 + 1, with outputs I and II shutting down without delay, and outputs III and IV with a delayed shutdown function. - **Technical Parameters**: The operating temperature range is generally -25°C to +60°C (some models can accommodate -40°C to +80°C). It can withstand voltages up to 300V and supports multiple power supply voltages, including 24V DC, 24V AC, 115V AC, and 230V AC. The power consumption is approximately 3W/4VA. Contact Characteristics: Taking the 3TK2825-1AB2O as an example, the contacts are changeover type with a rated voltage of 24-240V AC/DC, meeting the connection and control needs of various circuits. Installation: Typically installed in a control cabinet with an IP32, IP43, or IP54 protection rating, it adapts well to industrial environments and ensures safe equipment operation. Applications: Widely used in industries such as metallurgy, petrochemicals, shipbuilding, environmental protection, electronic equipment, packaging, and precision machinery, ensuring safe equipment operation.
