Each output is rated at a nominal 2 A (permissible range 20 mA to 2.4 A), powered from a 24 VDC load voltage, with short-circuit protection and reverse-polarity protection absent from the load side. The module draws up to 28 mA from the backplane bus and typically 100 mA from the load supply when idle. ## Output Ratings and Derating Output current per channel is rated for 5 A or 4 A depending on temperature. Total module current cannot exceed 6 A. Switching frequency is application-dependent: resistive loads up to 30 Hz (symmetrical), inductive loads up to 0.1 Hz, lamp loads up to 10 Hz. The module includes wire-break monitoring for the output lines, detecting open circuits in the range 12 Ω to 1 kΩ. ## Safety and Diagnostics The module is certified for safety applications to SIL 3 and Category 4, with a group error LED (SF red) and per-channel diagnostics. Galvanic isolation exists between channels and the backplane bus; no isolation between channels. Maximum residual current for a '0' signal is 0.5 mA for both sourcing and sinking configurations.","metaTitle":"Siemens 6ES7138-4FB04-0AB0 SIMATIC DP 4DO 2A SIL3","metaDescription":"Active production 4-channel transistor output module with diagnostics, wire-break detection, SIL 3. 2 A per channel, 30 mm wide ET 200S slice.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Output Modules"],"specifications":{"Depth":"52 mm","Width":"30 mm","title":"6ES7138-4FB04-0AB0","Height":"81 mm","Wire-break":"Yes","Lower Limit":"12 Ω","Upper Limit":"1 kΩ","description":"SIMATIC DP, Electronics module for ET 200S, 4 F-DO PROFIsafe, 24 V DC/2 A, 30 mm overall width, up to PL E (ISO 13849), up to SIL 3 (IEC 61508), can also be used in PROFINET configuration with IM 151-3 HF","For Uprating":"No","Short-circuit":"Yes","Shielded, Max.":"500 m","acc. to EN 954":"4","Weight, approx.":"85 g","lifecycle_stage":"current","Power loss, typ.":"3.5 W","Rated value (DC)":"24 V","Unshielded, Max.":"500 m","On Lamp Load, Max.":"10 Hz; Symmetrical","up to 40 °C, max.":"4 A","up to 55 °C, max.":"5 A","up to 60 °C, max.":"4 A","Between The Channels":"No","Diagnostics function":"Yes","For Signal \"1\", Min.":"L+ (-2,0 V), current sourcing switch: L+ (-1,5 V), voltage drop on current sinking switch: max. 0.5 V","Group error SF (red)":"Yes","SIL acc. to IEC 61508":"SIL 3","Type of digital output":"Transistor","Current per module, max.":"6 A","Short-circuit protection":"Yes","Number of digital outputs":"4","With Inductive Load, Max.":"0.1 Hz; Symmetrical","With Resistive Load, Max.":"30 Hz; Symmetrical","For Signal \"1\" Rated Value":"2 A","Controlling a digital input":"No","Reverse polarity protection":"No","For Redundant Control Of A Load":"No","from backplane bus 3.3 V DC, max.":"28 mA","From load voltage L+ (no load), typ.":"100 mA","For Signal \"0\" Residual Current, Max.":"0.5 mA; Current-sourcing and current-sinking switches","Between The Channels And Backplane Bus":"Yes","For Signal \"1\" Permissible Range, Max.":"2.4 A","For Signal \"1\" Permissible Range, Min.":"20 mA","Status indicator digital output (green)":"Yes","Between the channels and load voltage L+":"No","Performance level according to ISO 13849-1":"PLe","Limitation of inductive shutdown voltage to":"Typ.
