440G-TZS21UPLH, Allen Bradley Guardmaster 440G-TZ Solenoid Interlock Switch Power to Lock 24 V dc

Allen Bradley Guardmaster Safety Interlock Switch

The Allen Bradley Guardmaster TLS-ZR-GD2 series high-tech, guard locking safety interlock switch has a supply voltage rating of 24VDC. It has 2PNP safety and 1PNP auxiliary contacts. It is used as part of a guard locking system to achieve performance level e. In the mechanical configuration, they are identical to the existing with the exception that they include an additional RFID door target. This switch is close-coupled mounted with the help of a fully-flexible actuator. It has a built-in microprocessor technology and 2 channel OSSD solid-state outputs. Locking/unlocking is achieved using a logic-level signal input. The RFID door target is uniquely coded and provides the internal microprocessor with additional door position information. Therefore, in the event of a broken or missing actuator key, the microprocessor will shut down the OSSD safety outputs. Each switch has semiconductor OSSD safety outputs that may be connected in series with other safety components that also have OSSD solid-state outputs (for example, the SensaGuard™ range of non-contact switches). A stainless-steel actuator guide is fitted to protect the unit from actuator damage due to poor guard alignment or guard wear.

Warning:
Due to stock no. 890-2985 being a power-to-lock switch, provisions may be required to ensure that a dangerous situation cannot result from open circuit faults or power failures.
