Use attached product manuals when available. If the manual is not public yet, request the full file directly through RFQ.
Commercial Path
Product pages on DRIVEKNMS are designed to verify model, brand and series first, then move the buyer into one clean quotation path.
Technical Dossier
The S231 architecture was introduced by Rofin-Sinar as a modular control platform designed to interface with the company's DC-series and Slab laser resonators. Early revisions (S231-01 through S231-03) provided analog power control and basic interlock monitoring via discrete I/O. Mid-generation revisions introduced RS-232 and RS-485 serial communication interfaces, enabling integration with external CNC controllers and PLC systems from Siemens, Fanuc, and Mitsubishi. Later variants incorporated expanded diagnostic registers and improved thermal management circuitry to address field reliability issues identified in high-duty-cycle welding applications.
Compatibility across S231 sub-variants is not universal. Firmware versions are hardware-locked to specific PCB revisions, and substitution of one sub-variant for another requires verification of the resonator interface pinout and power bus rating. Facilities migrating from S231-series controllers to Rofin's subsequent SLOMO or PowerLine control platforms must account for protocol translation and I/O remapping. The S231 series is now classified as end-of-life (EOL) by Rofin (now Coherent Corp.), with no new production. All procurement is sourced from tested surplus and refurbished inventory.
The following SKUs represent the documented S231 series module range. Each entry reflects a distinct hardware configuration within the platform:
S231-01: Base laser controller, analog power regulation, single-channel output
S231-02: Enhanced controller module, dual-channel I/O, RS-232 serial interface
S231-03: High-power variant controller, extended current range, thermal protection relay
S231-04: Modulated output controller, PWM signal generation, external trigger input
S231-05: Diagnostic controller module, onboard fault logging, LED status array
S231-10: DC power supply module, 24 VDC regulated output, overcurrent protection
S231-11: High-voltage power supply, resonator excitation circuit, capacitor bank assembly
