Spin Bridge Pinout

The SpinBridge provides the following electrical interfaces:

  • 4-pin terminal socket for safety (OSSD + 24V/0V supply)

  • M12 power connector (48V motor supply)

  • M12 communication connector (tool interface)

  • USB 2.0 host

  • 2 × Ethernet ports (1: External network, 2: Robot connection)

  • Factory reset button

  • USB Micro (service port – do not use)

  • LED status indicators

Note

The SpinBridge acts as the central interface between:

  • The SD/SDV-Series tool

  • The robot or PLC

  • The safety system

All electrical connections to the tool are routed through the SpinBridge.

Warning

Incorrect wiring or missing connections may result in:

  • Loss of communication

  • Failure of safety functions

  • Unstable system behavior

Always verify all connections before operation.

Safety Terminal (OSSD Interface)

Safety terminal pinout

Pin

Signal

1

0V (from robot / safety supply)

2

+24V (from robot / safety supply)

3

OSSD A (safety output channel A)

4

OSSD B (safety output channel B)

Note

The safety interface is powered externally by the robot or PLC.

OSSD signals are dual-channel, pulse-tested safety outputs.

Important

The robot or PLC must monitor both OSSD channels.

A safe stop must be initiated if either channel goes low.

Note

The SpinBridge provides safety-related signals but does not perform the safe stop function.

The safe stop must be implemented by the robot or PLC.

48V Motor Supply Interface

The 48V motor supply is generated and supplied by the SpinBridge.

  • The internal power supply provides 48V for the screwdriver motor

  • The supply is internally switched and forwarded to the tool

Note

The 48V circuit can be interrupted via:

  • Internal control (software)

  • External safety relay (via I/O connector, 48V motor loop (48V in/out))

Refer to I/O module for details.

Important

Removing the 48V supply ensures that the motor is fully de-energized.

Tool Communication Interface (M12)

The M12 communication connector provides:

  • RS485 communication

  • 24V supply for tool electronics

  • Internal routing of safety signals from the tool

Note

Refer to SD/SDV-Series Pinout Interface for detailed pin assignments.

Ethernet Interfaces

The SpinBridge provides two RJ-45 Ethernet ports:

  • Port 1 – External network (service, configuration, OPC-UA)

  • Port 2 – Robot connection

Important

Always connect the robot controller to Port 2.

Note

Only one control interface should be active at a time.

USB Interfaces

The SpinBridge includes:

  • USB Host (for external devices)

  • USB Micro (service interface - DO NOT USE)

Warning

The USB Micro port is for service use only and must not be used during normal operation.

I/O Module

The I/O module is available on all SpinBridge variants.

It enables control of the SD/SDV-Series without robot-specific software.

Warning

Ensure that both robot and SpinBridge are powered off before connecting the I/O module.

The I/O interface:

  • Complies with IEC 61131-2

  • Is galvanically isolated

  • Is powered externally via the safety connector (24V / 0V from robot)

Inputs 1–8 (from robot)

Important

The 48V motor supply loop can be interrupted via the I/O connector.

This allows integration of an external safety relay to ensure complete removal of motor power.

Note

All I/O signals are referenced to the external 24V/0V supply provided by the robot or PLC.

Note

Refer to the Dashboard manual for configuration of I/O functions.
