ABB pluto b46 v2 abb safety controller

Why Choose the ABB Pluto B46 v2 2TLA020070R1700 Safety Controller?

The ABB Pluto B46 v2 2TLA020070R1700 is a compact and powerful programmable safety controller / safety PLC developed for advanced industrial machine safety applications. Part of the ABB Jokab Safety Pluto family, it combines extensive safety I/O with the Pluto Safety Bus, allowing multiple safety functions and devices to be managed within a flexible programmable architecture.

The Pluto B46 v2 provides a total of 46 I/O, comprising 24 failsafe inputs, 16 configurable non-failsafe outputs/failsafe inputs, 4 individually failsafe relay outputs and 2 individually failsafe transistor outputs. This high I/O capacity makes the controller particularly suitable for machinery with multiple emergency stops, guard switches, safety sensors and other protective devices.

Operating from a 24 V DC supply, the Pluto B46 v2 supports Pluto Safety Bus, MODBUS ASCII and StatusBus communication and is programmed using ABB Pluto Manager software. Its compact 90 × 84 × 120 mm enclosure provides substantial safety-control capability while conserving control-panel space, with safety functions capable of achieving up to PL e and SIL 3 when correctly designed and validated.

Key Advantages

• 46 total I/O provides extensive capacity for sophisticated machine safety systems.

Flexible Programmable Control for Complex Machine Safety

The ABB Pluto architecture enables numerous machine safety devices to be incorporated into programmable safety functions rather than requiring a separate safety relay for every individual function. The Pluto B46 v2 offers 24 dedicated failsafe inputs alongside 16 configurable I/O points, allowing emergency stops, guard switches, safety sensors and other protective equipment to be integrated into a central safety-control strategy.

For larger installations, Pluto Safety Bus allows compatible Pluto controllers to exchange safety-related information, supporting distributed safety architectures across machinery and production lines. With six individually failsafe outputs, flexible programming through Pluto Manager and safety capability up to PL e and SIL 3, the B46 v2 is well suited to applications requiring both high I/O capacity and scalable safety control.

Typical Applications

• Automated production and assembly machinery.
• Robotic cells and manufacturing systems.
• Multi-zone machine safety control.
• Packaging and processing equipment.
• Conveyor and material-handling systems.
• Complex machinery with multiple safety devices and protective functions.
