Custom 3-Channel Particle Counter Control Rack | Siemens Simatic S7-1200 PLC |.
Up for sale is a high-quality, custom-built 3-Channel Control & Interface Rack for Particle Counters.
This unit was professionally engineered as a centralized hub to power, control, and manage data for up to three independent particle counters simultaneously (ideal for cleanrooms, environmental monitoring, or laboratory automation).
Built into a rugged 19" subrack, this unit features premium industrial-grade components including a Siemens S7-1200 PLC system and a Phoenix Contact network switch.
As seen in the photos, the unit is in excellent, clean cosmetic condition and appears to have been pulled from a working environment.

Condition Note
Used / As-Is: The unit is in excellent cosmetic shape with pristine internal wiring. It powers on cleanly via the main switch. Because this is a specialized custom PLC assembly, we are unable to fully test software programming or individual pneumatic logic, so it is being sold As-Is / Working-Condition implied by environment pull.
