The 6ES7142-1BD30-0XA0: This is a spare-part listing for the SIMATIC DP EM 142 output block—4 digital outputs at 0.5 A each, M12 connector, IP65, and made for the ET 200X distributed system where you need dry-area protection. Lifecycle is current, so it's not a scavenger hunt—still rolling off the line.
Each output handles 0.5 A at 24 V DC, but the module's total is derated to 2 A at 55 °C—watch your group load if the panel runs hot. Short-circuit protection is electronic; the response threshold trips typically at 1 A. Switching frequency hits 100 Hz on resistive loads, but drops to 1 Hz on lamp loads—inductive or incandescent, that's your limiter. Unshielded cable runs up to 30 m, fine for local I/O.
Described as a spare part but lifecycle is current—Siemens still runs this line. We quote against RFQ; typical lead time mirrors the current production schedule. No LTB or EOL announced.
