The Omron G9SX-AD322-T15-RC DC24 is a general-purpose safety controller rated to Category 4, PLe, and SIL3. It runs on a 24VDC supply and packs six solid-state safety outputs plus two auxiliary solid-state outputs, with two digital inputs. The built-in delay timer adjusts from 0 to 15 seconds, and the logical AND I/O lets you cascade units without extra wiring.
SIL3 and Category 4 / PLe cover the highest safety integrity for machinery risk reduction — think emergency stops, light curtains, or two-hand controls on presses or robotic cells. The six solid-state safety outputs switch loads directly without external contactors for smaller applications, but watch the total current budget: solid-state outputs have a per-channel and package limit not listed here, so size your load accordingly. The two auxiliary outputs mirror status or fault signals to a PLC. The 0–15 second delay is adjustable on the unit itself — no software needed. That covers off-delay for guard door monitoring or timed restart inhibits. The logical AND I/O means you can daisy-chain multiple G9SX units so all inputs must be satisfied before outputs turn on, which simplifies wiring on multi-zone machines.
Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded wire — strip to 8 mm. The 24VDC supply is polarity-protected but not reverse-voltage protected; double-check polarity before powering.
