It is designated as a spare part, meaning it is not in current-series production but remains available through independent distribution channels for installed-base support. Each output is electronically short-circuit protected, with a typical response threshold of 1.8 A, and the module provides a status indicator (green LED) per channel for on-site fault isolation. ## Output ratings and derating in the panel The 8 outputs are rated 1.2 A per channel at 24 V DC, with a permissible range from 5 mA to 1.3 A. The total current from the load voltage 2L+ is limited to 7 A at ambient temperatures up to 20 °C, derating to 5 A at 55 °C — so a full 8-channel load at 1.2 A each (9.6 A total) exceeds the module's thermal budget and requires grouping or derating per the installation guidelines. Switching frequency with resistive load reaches 100 Hz; with lamp load it drops to 1 Hz, which governs the choice of downstream contactor or solenoid. The inductive shutdown voltage is clamped to typ. (2L+) -47 V, protecting the output stage from flyback spikes. ## Physical fit and environmental sealing Unshielded cable runs up to 30 m are permitted per channel. Isolation between the backplane bus and all other circuit components is tested at 500 V DC, with channel-to-channel isolation not provided — adjacent outputs share a common group.","metaTitle":"Siemens 6ES7142-1BF30-0XA0 EM 142 8 DO DC 24V/1.2A, IP66/67","metaDescription":"Siemens 6ES7142-1BF30-0XA0 spare part: EM 142 expansion module for ET 200X, 8 digital outputs at 24 V DC / 1.2 A per channel, M12, IP66/67.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Output Modules"],"specifications":{"Depth":"55 mm","Width":"87 mm; Width module 60 mm","Alarms":"No","Height":"180 mm","Lower Limit":"21 Ω","Upper Limit":"4 kΩ","For Uprating":"No","Weight, approx.":"350 g","lifecycle_stage":"current","Power loss, typ.":"1.5 W","Unshielded, Max.":"30 m","On Lamp Load, Max.":"1 Hz","up to 20 °C, max.":"7 A","up to 55 °C, max.":"5 A; Up to 50 °C","Between The Channels":"No","For Signal \"1\", Min.":"2L+ (-1,2 V)","Isolation tested with":"500 V DC","Response threshold, typ.":"1.8 A","Short-circuit protection":"Yes; Electronic","Number of digital outputs":"8","With Resistive Load, Max.":"100 Hz","Between Different Circuits":"75 V DC/60 V AC","For Signal \"1\" Rated Value":"1.2 A; At 24 V DC","Controlling a digital input":"Yes","For Redundant Control Of A Load":"Yes; only outputs of the same group","from backplane bus 5 V DC, max.":"35 mA","For Signal \"0\" Residual Current, Max.":"0.5 mA","For Signal \"1\" Permissible Range, Max.":"1.3 A","For Signal \"1\" Permissible Range, Min.":"5 mA","Status indicator digital output (green)":"Yes","from load voltage 2L+ (without load), max.":"12 mA","Limitation of inductive shutdown voltage to":"Typ.
