QR code links to the 440G-LZ User Manual Bright 270 degree wrap-around LEDs provide status and smart local diagnostics 440G-LZ The Allen-Bradley Guardmaster 440G-LZ from Rockwell Automation is a guard locking switch designed for partial body access guards. Combining microprocessor technology with an RFID coded actuator, the 440G-LZ features a locking bolt drive mechanism that will only lock when the correct actuator is detected. The locking bolt is continuously monitored for correct insertion within the actuator. This extra functionality allows the 440G-LZ to be certified PLe, Cat 4 , SIL 3 – the highest level of safety for guard position and lock monitoring – and it can be connected directly or in series with other PLe, Cat 4, or SIL 3 rated safety devices. The 440G-LZ runs “cool” and has low power (2.5 W) consumption due to its bi-stable solenoid and built-in energy storage. The 440G-LZ consumes up to 60% less energy when compared to other guard locking switches, making it a truly ‘green’ safety solution. It achieves this level of energy efficiency thanks to advanced algorithms and a bi-stable solenoid design that consumes little power for switching, regardless of whether it is in the locked or unlocked state. GuardLogix and Compact GuardLogix SmartGuard 600 TLS-Z Guard Locking Switch The TLS-Z features an RFID door target that is mounted with the supplied fully-flexible actuator. Using built-in microprocessor technology and two channel OSSD solid-state outputs, these switches operate using a logic-level signal input. The RFID door target is uniquely coded and provides the internal microprocessor with additional door position information. This device can be used in a guard locking system to achieve PLe, Cat 4 and SIL 3. • • • • • RFID unique (high) coded door target Power-to-Release (safety of people) and Power-to-Lock (protection of machine production) versions available Solid-state OSSD outputs allow the switch to be connected in series with other devices while maintaining safety ratings Meets EN/ISO 14119:2013, EN/ISO 13849-1 and EN 62061 PLe, Cat 4 and SIL 3 for guard position and lock monitoring 440G-LZ Features • TÜV certified to PLe, Cat 4 per EN/ISO 13849-1, SIL 3 per EN 62061 and EN/ISO 14119:2013 • Uses up to 60% less power than competitive products • RFID unique (high) or standard (low) coded actuators provide application flexibility • High holding force (Fzh) per EN/ISO 14119:2013 • Power-to-Release (safety of people) and Power-to-Lock (protection of machine production) versions available • IP69K washdown rating • Compact 45 mm housing with four actuator positions for flexibility of mounting Safety relays and configurable safety relays Variable speed and servo drives 5 SAFETY SWITCH SELECTION 1 Scan to learn more about safety switches and interlocks on ab.com Trapped Key Systems Is it a Sequential Access Control application?
