ABB 2TLA020070R4600 Safety Module

ABB 2TLA020070R4600 Safety Module

 

 

The ABB 2TLA020070R4600 is a Pluto B20 V2 safety PLC (programmable safety controller) from ABB’s Jokab Safety / Pluto series. It is used for machine safety control systems, not standard automation logic.

Product Information

• Brand: ABB (Jokab Safety)
• Series: Pluto B20 V2
• Part Number: 2TLA020070R4600
• Type: Safety PLC / Safety Controller (not a simple relay module)
• Power Supply: 24V DC
• I/O Capacity: 20 total I/O (configurable safety + standard signals)
• Safety Level: Up to Category 4 / PL e systems
• Mounting: DIN rail
• Programming Software: Pluto Manager

What it actually is

This device is a small safety PLC (not a relay, not a normal PLC I/O module).

It is designed to:

• Monitor safety devices (E-stop, light curtains, door switches)
• Execute safety logic programs
• Control safe outputs (machine stop circuits, safety relays, contactors)

System Role (simple)

Safety devices (E-stop, door switch, sensor)
→ Pluto B20 V2 safety PLC
→ evaluates safety logic
→ sends safe stop signal
→ machine power is cut via contactor / drive STO

Key Features

• Compact safety PLC with built-in I/O
• Safety bus communication (Pluto safety network)
• Supports distributed safety architecture
• Designed for machine-level safety control
• Redundant internal safety processing for reliability

Typical Applications

• Machine emergency stop systems
• Safety door interlocks
• Light curtain protection systems
• Conveyor safety zones
• Packaging / automation machine safety
• OEM machine safety control

Advantages

• Replaces multiple safety relays with one programmable unit
• Flexible safety logic (not hard-wired relay logic)
• Supports networked safety systems
• High safety integrity (PL e capable systems)
• Compact DIN-rail installation

Important Notes

• This is NOT a standard PLC (like ABB AC500 or Siemens S7)
• This is a dedicated safety PLC only for protection logic
• Programming requires Pluto Manager software
• Cannot be mixed directly with standard automation logic without proper safety design
• Used only in certified safety circuits

Precautions

• Must be configured by qualified safety engineers
• Incorrect wiring can disable machine safety functions
• Must follow PL / SIL safety design rules
• Do not bypass safety inputs or outputs
• Firmware + safety program must be validated before commissioning
