It talks PROFIBUS DP on the network side at up to 12 Mbit/s, with the bus interface isolated from the internal circuit components. Lifecycle stage is current — no phase-out or last-time-buy signal in the record — so a BOM line written against this order code can be quoted to an RFQ. ## Channel-side ratings that govern the fit Switching frequency derates hard by load class: 100 Hz on a resistive load, 1 Hz on a lamp load, and 0.5 Hz on an inductive load per IEC 60947-5-1 DC-13 — the headline number is not the figure to design to. Output short-circuit protection and reverse polarity protection are both present, and inductive shutdown is clamped to 2L+ (-44 V) so a free-wheel path is built in for DC solenoids. ## Power budget Rated supply is 24 V DC; the block draws a typical 70 mA from supply voltage 1L+ and a typical 60 mA from load voltage 2L+ with no load on the outputs. Power loss is typically 4 W, which is the number to fold into the cabinet thermal calc when the block sits in a sealed field enclosure. ## Digital-input read path (8DI side) Controlling a digital input from this block is supported, and redundant control of a load across two outputs is supported, which is the wiring mode to use for fail-safe valve pairs. ## Field-side wiring and diagnostics Field wiring lands on 4/5-pin M12 circular connectors, one per socket pair, and the housing envelope is 210 mm tall by 60 mm wide by 28 mm deep at roughly 210 g — a flat block that drops between standard cable duct runs. Unshielded drop length is allowed up to 30 m, which covers most machine-mount installations without ordering special cable. Diagnostics are readable over the bus, with a green per-output status LED and a group-error SF LED in red; there is no per-channel fault LED and no alarm slot, so a blown channel shows up at the group level only. Isolation between different circuits is rated at 75 V DC / 60 V AC, and the bus-to-internals isolation is tested at 500 V DC — enough headroom for mixed sensor supplies on the same backplane. ## Sourcing posture With lifecycle stage recorded as current, the order code is specified into the BOM on its own merits; no official successor or LTB cross-reference appears in the record, so no alternate order code is asserted from this ledger.","metaTitle":"Siemens 6ES7142-3BF00-0XA0, 8 DQ IP65/67, 24 V DC","metaDescription":"Siemens 6ES7142-3BF00-0XA0: 8 digital outputs, 24 V DC, 4 A per socket via M12, PROFIBUS DP up to 12 Mbit/s, IP65/67.
