IEC standard 62271-102 defines the functionality and features of a disconnector. Disconnectors have provisions for a lockout-tagout so that inadvertent operation is not possible. In high-voltage or complex systems, these locks may be part of a trapped-key interlock system to ensure proper sequence of operation.
Example IEC categories in standard 60947 are described as: AC-1 - Non-inductive or slightly inductive loads, resistance furnaces; AC-2 - Starting of slip-ring motors: starting, switching-off; AC-3 - Starting of squirrel-cage motors and switching-off only after the motor is up to speed. (Make Locked Rotor Amps (LRA), Break Full Load Amps (FLA))
At the master pin 1 to pin 3 provides 24V DC power with max. 200 mA for an optional power supply of the IO-Link device. Pin 4 is used as a digital input (DI) or digital output (DO) according to the IEC 61131-2 specification to allow backward compatibility to proximity sensors according to IEC60947-5-2 or other sensors or electrical switches.
