ABB pluto b42 as-i abb safety controller

Why Choose the ABB Pluto B42 AS-i 2TLA020070R1400 Safety Controller?

The ABB Pluto B42 AS-i 2TLA020070R1400 is a compact and powerful programmable safety controller / safety PLC designed for machine safety applications requiring flexible I/O, networked safety communication and AS-Interface integration. Part of the ABB Jokab Safety Pluto family, it combines an AS-i bus with the Pluto Safety Bus for efficient integration of safety devices across automated machinery and production systems.

The Pluto B42 AS-i provides a total of 42 I/O, comprising 20 failsafe inputs, 16 configurable non-failsafe outputs/failsafe inputs, 4 individually failsafe relay outputs and 2 individually failsafe transistor outputs. This flexible architecture allows numerous safety functions to be handled by a single programmable controller while reducing the amount of dedicated safety hardware required.

Operating from a 24 V DC supply and supporting AS-i, Pluto Safety Bus, MODBUS ASCII and StatusBus communication, the controller is suitable for distributed and networked machine safety systems. Its compact 90 × 84 × 120 mm enclosure is designed for DIN-rail installation inside control panels, while safety functions can achieve performance levels up to PL e when correctly engineered and validated.

Key Advantages

• 42 total I/O provides substantial capacity for complex machine safety applications.

Flexible Programmable Control for Machine Safety Systems

ABB Pluto safety PLCs are designed to allow safety devices such as emergency stops, safety switches, non-contact sensors, light curtains and other protective equipment to be incorporated into programmable machine safety functions. The Pluto B42 AS-i extends this capability with AS-Interface connectivity, allowing compatible AS-i safety devices and distributed I/O to be integrated alongside conventional safety circuits.

The combination of 20 failsafe inputs, 16 configurable I/O points and six individually failsafe outputs provides substantial flexibility for machinery with multiple safety zones and functions. Pluto Safety Bus communication also enables multiple Pluto controllers to exchange safety-related information, supporting scalable architectures for larger machines and interconnected production equipment.

Typical Applications

• Automated production and assembly machinery.
• AS-i Safety at Work installations.
• Robotic cells and automated manufacturing systems.
• Conveyors and material-handling equipment.
• Packaging and processing machinery.
• Multi-zone machine safety control systems.
