ABB Safety Controller, 24 Safety Inputs, 6 Safety Outputs - 2TLA Series - 2TLA020070R1700 Use this safety controller from ABB to provide critical control and safety for potentially dangerous processes. The special-purpose device uses two microprocessors to monitor and regulate parameter inputs and outputs for early discovery and correction of faults. Each processor has its own memory and programming software to ensure the integrity and accuracy of data. Connect up to 32 units in a 2-wire bus system for communications through a gateway or HMI (human-machine interface) display for complicated operations with expansive capacity. Features & Benefits • Robust and durable plastic housing that's rustproof for use in harsh conditions
• IP20 (ingress protection) rating indicates a touch-proof device that protects against electric shocks
• Dimensions of 84 (L) x 90 (W) x 118mm (D) make this unit compact and easy to install in limited spaces Applications • Robotics equipment
• Automated assembly lines
• Material handling systems What's the difference between a standard programmable logic controller (PLC) and a safety PLC? A safety PLC controls both safety and standards, while a regular PLC only controls standards. If you use a safety PLC it means you don't need to install additional safety relays, which are needed with regular PLCs.
