The Pilz S1WP 9A 110-230VAC/DC UM 0-415VAC 0% (890065) is a high-performance monitoring relay developed for supervising electrical voltages in industrial automation systems. As part of Pilz’s extensive family of monitoring relays and devices, it provides a dependable solution for maintaining operational safety, detecting irregularities in supply voltage, and preventing equipment damage in critical applications.

One of its most valuable features is its wide analogue measurement range of 0–415 V AC. This capability allows the device to supervise both low and higher-voltage systems, making it a versatile option across diverse industrial environments. By providing broad coverage, the relay reduces the need for multiple specialised monitoring devices, streamlining system design and lowering overall costs.

The relay supports supply voltages of 110–230 V AC/DC, enabling global compatibility and simplifying deployment across international operations. This flexibility allows companies to standardise on a single device type for multiple facilities, reducing inventory and maintenance complexity.

Despite its robust functionality, the device maintains efficient energy consumption, with a power draw of only 5 VA when supplied by AC. This efficiency contributes to lower operational costs and reduces heat buildup in densely packed control cabinets, ensuring longer service life for both the relay and surrounding components.

Installation and wiring are straightforward, as the relay supports conductor cross-sections suited for standard industrial cabling practices. This ensures secure, reliable connections and simplifies integration into new systems or retrofitted applications.

Functionally, the S1WP relay provides continuous supervision of input voltages, helping detect undervoltage, overvoltage, or total supply loss. Early detection of these irregularities is vital for protecting sensitive electrical equipment, preventing downtime, and maintaining a safe operating environment. In automation systems, these functions also support compliance with safety standards, giving operators greater confidence in system reliability.

The device is well-suited for industries such as manufacturing, energy, logistics, and process control, where consistent voltage monitoring is essential. Applications include monitoring supply voltage for control panels, protecting motor systems, or supervising critical machinery where power fluctuations could disrupt operations or cause hazards.

As with all Pilz products, the S1WP 9A 110-230VAC/DC UM 0-415VAC 0% is engineered to the highest standards of quality, reliability, and safety. Its rugged design ensures long service life and dependable operation, even under challenging industrial conditions.

In summary, the Pilz S1WP 9A 110-230VAC/DC UM 0-415VAC 0% (890065) is a versatile and efficient monitoring relay offering broad input voltage supervision, flexible supply compatibility, and low energy consumption. Built to deliver reliability in safety-critical environments, it is an essential tool for industries that depend on stable, uninterrupted voltage monitoring to keep operations safe and productive.
