A control circuit is an essential part of electrical systems that allows for the control and management of various electrical devices. It acts as a relay point between a power source and devices, receiving input from sensors and sending instructions to control the actions of connected devices.

Devices for electrical safety are tools or equipment engineered to guard against electrical risks and safeguard individuals, property, and equipment from possible threats linked to electricity. These devices are utilized in both industrial and residential settings to guarantee the secure usage and handling of electrical systems.

Industrial I/O (input/output) modules are critical industrial network components that deliver input signals from a field device, such as a sensor or actuator, to a controller.
