Safety relay is an electromechanical device that monitors the safety functions of a machine and stops it if a safety issue is detected.

• Safety relays are used to monitor safety functions such as emergency stops, guard doors, light curtains, etc.

• They work by using input signals from safety devices to determine if the machine is in a safe state.

• If a safety issue is detected, the safety relay will open its contacts and sto...read more

Ohm's Law is a fundamental principle in electrical engineering that relates the current flowing through a conductor to the voltage across it and the resistance of the conductor.

• Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across it and inversely proportional to the resistance (R) of the conductor.

• The formula for Ohm's Law is: V = I * R, where V is the vol...read more
