Control Relay Module

A control relay module is an integral part of the Boundary Definition Interface system that provides electrical isolation and switching capabilities to establish and maintain operational boundaries. It receives low-power control signals from the interface controller and uses electromagnetic relays to switch higher-power circuits that define physical or logical boundaries in industrial equipment. This module ensures safe separation between control systems and power systems while enabling precise boundary definition through electrical switching. The module is designed for use in electrical equipment manufacturing, where it functions as a component that manages power distribution and control signals. It operates on electromagnetic principles, where a low-voltage control signal energizes an electromagnet, which mechanically closes or opens contacts to switch higher-voltage circuits. When the Boundary Definition Interface sends a boundary definition command, the module activates specific relays to establish electrical boundaries that correspond to operational limits, safety zones, or functional areas within the equipment. The module is available with a rated control voltage of 24 V DC ±10%, contact ratings of 10–250 V AC, and contact currents of 5–10 A. It features 2–4 contacts, configurable as NO/NC combinations, and a switching frequency of up to 3600 cycles per hour. Mechanical life is at least 10^7 operations under no-load conditions, and electrical life is at least 10^5 operations at rated load. The operating temperature range is -40 to 85 °C, with a degree of protection from IP54 to IP65 depending on housing. Dielectric strength is at least 2.5 kV between coil and contacts, and insulation resistance is at least 100 MΩ at 500 V DC. Coil power consumption ranges from 1.5 to 3.0 W, response time is up to 20 ms, and weight varies from 0.2 to 0.5 kg. Materials used include copper, plastic, and steel. All values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. Standards such as IEC 60947-5-1, IEC 60068-2-1/2, IEC 60529, and IEC 60947-1 are listed as procurement references, not as proof of certification or compliance.

When the Boundary Definition Interface sends a boundary definition command, the module activates specific relays to establish electrical boundaries that correspond to operational limits, safety zones, or functional areas within the equipment. The module provides electrical isolation between control and power circuits, ensuring safe operation. The switching action is mechanical, with a response time of up to 20 ms from coil energization to contact closure. The module supports configurable NO/NC contact combinations, allowing flexible boundary definition. The operating principle relies on the coil power consumption of 1.5–3.0 W to energize the electromagnet, and the contacts are rated for 10–250 V AC and 5–10 A continuous current.
