The Pilz PIT ESB2.4 CONTACT BLOCK 1 N/C 1 N/O (part no. 400306) is a durable and versatile contact block designed for use with emergency stop (E-STOP) and control devices in industrial automation. As part of the PITcontrol and signal device series, this component offers a reliable solution for integrating functional safety into machine and system operations.

One of its key strengths is its dual-contact configuration, combining 1 normally closed (N/C) contact with 1 normally open (N/O) contact. This setup provides engineers with flexibility in wiring and circuit design, allowing the block to simultaneously carry out safety-related switching functions and auxiliary signalling. The N/C contact can be used to interrupt safety circuits, ensuring dangerous machine movements are stopped immediately when the E-STOP is activated, while the N/O contact can be used for status indication, diagnostics, or control feedback.

The device is constructed with AgNi (silver-nickel) contacts, ensuring excellent conductivity and resistance to wear. This material choice enhances durability, reduces the risk of contact failure, and supports reliable long-term operation even under frequent actuation. The block also features a minimum contact current rating of 1 mA, allowing it to operate reliably with low-level control signals without performance loss.

Designed for challenging industrial environments, the PIT ESB2.4 supports a wide ambient temperature range from -30 °C to +85 °C. This ensures dependable performance in environments ranging from cold storage areas to high-heat production facilities. Furthermore, it complies with pollution degree 3 creepage and clearance standards, ensuring reliable insulation and protection against contamination common in industrial workplaces.

The contact block is tested and certified in accordance with EN 60947-5-1, the international standard for low-voltage switchgear and controlgear. This compliance provides assurance that the device meets strict safety and performance requirements for emergency stop functions, making it suitable for use in safety-critical circuits.

As part of the Pilz PIT system, the ESB2.4 contact block is designed for seamless integration with other Pilz control and signal devices, such as E-STOP pushbuttons and operator elements. Its modular construction allows quick installation, easy replacement, and straightforward maintenance, helping to reduce downtime and simplify system configuration.

Typical applications include automotive manufacturing, packaging machinery, robotics, process industries, and general machine building, where E-STOP functionality and operator safety are paramount. By combining robust design with flexibility, the PIT ESB2.4 ensures that machine safety is not only effective but also adaptable to diverse system requirements.

In summary, the Pilz PIT ESB2.4 CONTACT BLOCK 1 N/C 1 N/O is a reliable, standards-compliant component that enhances the safety and flexibility of control systems. With its dual-contact configuration, AgNi materials, wide temperature tolerance, and EN 60947-5-1 compliance, it provides an essential foundation for building dependable emergency stop and operator control solutions in modern industrial environments.
