The Pilz S1MO 48VAC 2C/O monitoring relay is a dependable and compact monitoring device designed for supervising system conditions in industrial automation environments. Part of Pilz’s trusted S1 monitoring relay series, it is tailored for 48 V AC supply systems, making it especially suitable for low-voltage monitoring applications where accuracy and reliability are essential.

At the heart of its design are two changeover contacts (2C/O), which provide flexibility for engineers and system designers. These contacts can be used for a range of functions, including triggering alarms, initiating system shutdowns, or switching auxiliary circuits in the event of a fault. The redundancy offered by dual contacts enhances safety and allows for versatile configuration to meet application-specific requirements.

The relay is equipped with a precise response threshold of 3.6 kΩ ±10%, ensuring that deviations in monitored values are detected quickly and accurately. This sensitivity supports the early identification of potential issues, helping to protect machinery, electrical equipment, and operators from risks associated with faults or abnormal operating conditions.

With a low power consumption of just 3.5 VA, the S1MO 48VAC 2C/O provides energy-efficient performance, making it suitable for continuous operation without significantly impacting overall system power demand. Its efficiency also contributes to reduced heat generation, improving the durability of both the relay and surrounding components in compact control cabinets.

The relay is built to withstand the challenges of industrial environments, with a robust housing and compact footprint that allow for reliable integration into control panels. This design makes it particularly valuable for installations where space is limited but monitoring reliability cannot be compromised.

Typical applications include low-voltage motor protection, monitoring of auxiliary control circuits, conveyor systems, process control equipment, and general safety monitoring tasks. Its ability to deliver accurate supervision at 48 V AC makes it a versatile tool for specialised setups where higher-voltage relays may not be suitable.

Like other Pilz monitoring devices, the S1MO 48VAC 2C/O is manufactured in accordance with international standards to ensure compliance, safety, and long-term reliability. It integrates seamlessly with broader Pilz safety and automation systems, enabling efficient and standards-compliant safety solutions across multiple industries.

In summary, the Pilz S1MO 48VAC 2C/O monitoring relay provides a compact, efficient, and highly reliable solution for low-voltage monitoring. With its dual changeover contacts, precise response threshold, energy-efficient design, and robust construction, it is ideally suited to industrial environments where reliable voltage supervision and control are critical.
