The problem

Life validation of 16 ovens needs 16 operators shifting doors and logging counts; a power failure voids weeks of counting. This bench runs 16 units in parallel with servo doors and full data logging.

Capability

16 stations (4x4), 4 modular 4-station units with aviation connectors, movable separately; 40x40 thickened aluminum frame (wall >=2.0mm); servo-driven door open/close (24V DC, ratio 1:40); 16 independent power-sampling modules (+/-0.5%, 0-250V/0-16A) over RS485; strong/weak/signal wiring physically separated; single-station fault stops only that station; UPS + resume-after-power-failure; timing accuracy +/-1s, 6-segment sequence programming; Siemens S7-1200 PLC; 15-inch industrial tablet (i3/8G/256G SSD/Win10); data storage >=3 years, Excel/CSV export, fault log; independent start/stop per unit; braked leveling casters.

Key specifications
