Arteche Time Delay Relay TDJ-8: Unmatched Versatility in Electrical Timing 

Time delay relays play a vital role in electrical systems by ensuring controlled and precise timing of electrical signals. The Arteche Time Delay Relay TDJ-8 is a multi-function relay designed to operate efficiently in extreme conditions, offering a wide range of timing options.

With 10 different functions, the TDJ-8 allows engineers to configure the relay for:

• Pick-up time delay – Delays the activation of the output contacts after receiving an input signal.
• Drop-out time delay – Ensures that the output contacts remain engaged for a preset time after deactivation.
• Cyclic timing – Alternates between on and off states for periodic operations.

Additionally, this relay provides an extensive timing range, from a few milliseconds to several hours, all within a single unit. This flexibility ensures seamless integration into various industrial and power applications.

Time Delay Relay TDJ-8: Robust Construction for Demanding Environments

Critical applications require relays that can withstand harsh conditions, and the Arteche DJ-8 Relay is built precisely for that purpose. Whether installed in substations, power generation facilities, or railway systems, this relay maintains consistent performance under extreme environmental stresses.

• High Breaking Capacity: Arteche time delay relays can incorporate magnetic blowout technology, significantly increasing their breaking capacity. This feature is essential for handling high inductive loads, ensuring safe and reliable operation.
• Resistance to Seismic and Vibrational Stress: The Time Delay Relay TDJ-8 endures vibrations and seismic activity, making it ideal for installations in locations prone to movement or mechanical disturbances. This feature is crucial for nuclear power plants, railways, and heavy industrial applications, where system stability is non-negotiable.
• High Dielectric Strength and Galvanic Isolation: One of the standout features of the Arteche TDJ-8 is its high dielectric strength, providing galvanic isolation between circuits. This ensures that electrical surges or faults in one section of the system do not affect other connected devices, enhancing overall system safety.

Superior Contact Configuration and Connectivity: Arteche Time Delay Relay TDJ-8

The TDJ-8 time delay relay features an 8PDT (8 Form-C) changeover contact configuration, allowing engineers to design complex switching and control logic efficiently. It supports J-type and J-large-type sockets, ensuring easy installation and maintenance.

Furthermore, the relay complies with international electrical standards, including:

• IEC 61000 – Electromagnetic compatibility standards.
• IEC 60947 – Low-voltage switchgear and control gear standards.
• IEC 60255 – Standards for measuring relays and protection equipment.
• ANSI C37.90 – Standards for protective relays and relay systems.

This compliance guarantees interoperability with existing protection systems, making the Arteche DJ-8 Relay a seamless upgrade or replacement option for older relays.
