ABB 2TLA020006R2400 Safety Module

The ABB 2TLA020006R2400 is the JSHD4-4 safety enabling device (handheld control switch top section) used in machine safety systems, especially for robot and maintenance operation safety control.

Product Information

• Brand: ABB (Jokab Safety)
• Part Number: 2TLA020006R2400
• Series: JSHD4
• Type: Safety enabling switch / handheld control device (top part)
• Function: 3-position safety enabling control (deadman switch style)
• Protection level: IP65
• Operation: 3-position (OFF – ENABLE – OFF safety logic)
• Voltage: 24V DC (control signaling)
• System role: Human safety control for machines/robots

What it actually is

This is a “deadman switch” safety enabling device, meaning:

• Operator must hold it in a safe middle position to enable machine movement
• If released or fully pressed → system immediately stops for safety
• Used to prevent accidents during maintenance or teaching mode

It is commonly used with:

• Industrial robots
• CNC machine maintenance
• Automated production lines
• Machine setup / commissioning

System Role (Simple)

Robot / machine in maintenance mode
→ operator holds JSHD4 enabling switch (2TLA020006R2400)
→ safety system allows motion
→ release or squeeze hard → system stops immediately

Key Features

• 3-position safety enabling function (deadman principle)
• High safety level (up to PL e in system design)
• Ergonomic handheld design for operator use
• IP65 protection (industrial environment resistant)
• Anti-tamper design depending configuration
• Designed for Jokab / ABB safety systems

Typical Applications

• Robot teaching / programming mode
• Maintenance operation on machinery
• Safe manual movement of automated systems
• Industrial safety interlock procedures
• Machine commissioning and testing

Important Notes

• This is NOT a PLC module ❌
• This is NOT a relay or controller ❌
• This is a safety input device (human-operated switch) ✔
• It must be used with a safety PLC or safety relay system

Precautions

• Must be connected to certified safety system (Pluto / safety PLC / relay)
• Incorrect wiring can disable safety function
• Should not be bypassed or modified
• Must be used only in maintenance/teaching mode scenarios
• Requires proper safety circuit design (PL/SIL compliance)
