Axiomtek AX92353 4-Ch PCIe Lighting Control Module

Machine vision lighting needs to fire at the moment of exposure and at a repeatable brightness, or image quality drifts from part to part. The AX92353 is Axiomtek’s 4-channel lighting control module for this job. It cannot operate on its own: Axiomtek states it must be used with the AX92352 encoder card with real-time trigger I/O, and it ships with a cable for communication with that card. We specify the pair for inspection systems we build.

The module has four independent, current-controlled LED driver channels with a 24 V DC output. In trigger mode each channel delivers 0.5 A for a duration of 10 ms to 65 s. In strobe mode each channel delivers 1 A for 10 us to 10 ms. Output current is set by software in 50 mA steps, which gives fine control of intensity.

Software also sets the duration and delay time of each LED output, so lighting can be aligned with the trigger and exposure from the AX92352. That card handles encoder input and camera triggering, while this module drives the lights. For camera links, the AX92325-4PoE powers four GigE cameras on M12 connectors in the same Axiomtek range.

LED heads connect through an 8-pin terminal connector, and the packing list includes a 4 x 2 terminal block. Power comes through a 6-pin ATX power connector at 12 V, with 60 W at 12 V DC in trigger mode and 120 W at 12 V DC in strobe mode, so the host supply must cover that load. The module measures 151 x 80 mm. Axiomtek also lists an LED power cable for its IPC962 and IPC964 systems.
