Technical details and manufacturing context for Control Relay Module

Definition
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.
Working Principle
The control relay module 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.
