Module overview
Siemens S7-1200 digital I/O module 6AG1223-1BL30-2XB0 packs 16 inputs and 16 outputs on 24 VDC, rated from -40 °C to 70 °C. On-board diagnostics and alarm functions reduce fault-finding time on the line. Carries cULus, CE, and FM approvals for plant-floor installation globally.
Sourcing and lifecycle
Lifecycle status is current — no phase-out or last-time-buy to chase. Sourced to order against an RFQ.
Integration notes
Input thresholds: signal '1' at ≥20 VDC, 4 mA typical; signal '0' at ≤0.1 VDC with 10 kΩ load. Switching delays: 0→1 in 50 µs max, 1→0 in 200 µs max. Unshielded cable run up to 150 m; shielded up to 500 m. Typical power loss 4.5 W from the backplane. No short-circuit protection onboard — fuse externally.
