Switching frequency is three different numbers depending on load: 100 Hz on a resistive load, 0.5 Hz on an inductive load per IEC 60947-5-1 DC-13, and 1 Hz on a lamp load — pick the one that matches the actuator, not the headline. Inductive shutdowns are clamped to 2L+ (-47 V), and the 0.1 mA max residual current at signal '0' keeps the off-state leakage from holding sensitive DC loads. ## PROFIBUS DP and node behaviour PROFIBUS DP runs up to 12 Mbit/s with the full baud ladder from 9,6 kbit/s to 12 Mbit/s, and the DP interface is isolated from the other on-board circuit components. The two supplies draw separately: 70 mA typical from 1L+ and 80 mA typical from 2L+ with no load, total power loss 4 W — budget both rails on the field power distributor rather than only the logic feed. Diagnostic information is readable over the bus, a group-error LED (SF, red) sits on the front, and per-channel fault indicators (F, red) are not present on this variant — fault triage is at the channel-mapping level in the controller, not the face of the node. Reverse-polarity protection is in place on the supply path, and the channels support controlling a digital input as well as redundant control of a load — useful for safety handshakes wired into the same M12 drop. ## Field-mount envelope and wiring The housing is sized for cabinet-free mounting: 60 mm wide, 210 mm tall, 28 mm deep, IP65/67 — install it on the machine frame close to the actuators and the M12 drops carry signal and load together, with PROFIBUS DP running up to 30 m on unshielded cable between nodes. Isolation between different circuits is rated 75 V DC / 60 V AC, and the bus interface is tested with 500 V DC — keep field wiring and PROFIBUS cable routed to preserve that separation on the machine. A channel-to-channel fault LED is not provided (F indicator marked 'No'), so the swap decision comes from the controller diagnostic buffer plus the green per-channel status indicator, not from a red dot on the slice. ## Spec at a glance Alarms are not part of the feature set on this node and there is no inter-channel isolation — group your loads accordingly when you lay out the M12 pin assignments.","metaTitle":"Siemens 6ES7142-3BH00-0XA0 ET200 DO 16×24V, 0.5A","metaDescription":"Siemens SIMATIC ET200 PROFIBUS DP digital output node, 16 outputs at 24 VDC / 0.5 A, IP65/67 M12, currently in production.
