System compatibility

109-0943-4A03-02 belongs to Rexroth Indramat RC35 servo drive system family,matched with RC35 series servo amplifier and synchronous servo motor.Widely applied in machine tools,automation assembly,press-fit and material handling workstations.This is a discontinued legacy spare part for equipment maintenance replacement.

Function

109-0943-4A03-02 is Rexroth Indramat RC35 servo drive I/O interface board.It processes digital input and output signals between RC35 servo amplifier and upper PLC system.It transmits drive enable,ready status,alarm and position handshake signals.It converts external switch signals into internal bus signals for motion control.It acts as signal interaction bridge between servo drive and peripheral automation control system.

Installation

Install 109-0943-4A03-02 into servo drive designated slot and lock fasteners.Connect I/O terminal wiring according to wiring drawing.Check 24V power polarity and equipment grounding before power-on.

Interface

‑24Vdc power input terminal

‑Digital I/O terminal block

‑Internal RC35 drive bus connector

‑Status and fault LED indicator

Circuit feature

Built-in ESD and surge suppression circuit,optocoupler signal isolation design,strong anti-electromagnetic interference performance for industrial workshop environment.

Feature

109-0943-4A03-02 is obsolete Rexroth spare part.Typical faults:I/O channel failure,intermittent signal loss,connector pin oxidation,circuit burnout.Inspect circuit board and connector pins before replacement.This board must match corresponding Indramat RC35 servo drive unit,direct substitution without inspection is not recommended.

Diagnostic

When I/O channel damage,optocoupler failure or bus communication fault occurs,the module triggers protection and lights up fault LED.

Built‑in function:Digital I/O signal transmission,optocoupler isolation,drive status interaction,status monitoring,self-diagnosis and fault alarm,used as Rexroth Indramat RC35 servo drive system spare replacement.
