That per-channel rating is the headline, but the real constraint is the total current: 6 A up to 20 °C, dropping to 4 A at 55 °C. If you're driving four solenoid valves at 1.5 A each, you're fine at 20 °C — at 55 °C you're over the limit and need to derate the load or add cooling. Channel-level diagnostics catch wire-break and short-circuit per output, with a parameterizable diagnostic alarm and a red group-error SF LED. That means a single bad solenoid or a pinched cable flags the exact channel, not just a vague module fault — saves hours of panel chasing on a line-down call. The module measures 87 mm wide (module body 60 mm) × 165 mm high × 67 mm deep including the connector. The 67 mm depth includes the front connector, so account for that when routing wires to the gland plate. Power dissipation is 2.5 W typical, and the module draws 40 mA max from the 5 V DC backplane bus plus 60 mA max from the 24 V load voltage when unloaded. The 24 V load voltage has a green monitoring LED — if that's out, the outputs won't fire, and the diagnostics will flag a load-voltage fault.","metaTitle":"Siemens 6ES7148-1CA00-0XB0 PM 148 Power Module, 4 DO 2 A","metaDescription":"Siemens 6ES7148-1CA00-0XB0 PM 148 power module with 4 digital outputs rated 2 A per channel at 24 V DC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Digital Output Modules"],"specifications":{"Depth":"67 mm; incl. connector","Width":"87 mm; Width module 60 mm","title":"6ES7148-1CA00-0XB0","Height":"165 mm","Wire-break":"Yes; channel by channel","Lower Limit":"12 Ω","Upper Limit":"4 kΩ","description":"***Spare part*** SIMATIC DP, Power module PM 148 for ET 200X 4 DO, 24V/2A DC with Load voltage supply channel diagnostics","For Uprating":"No","Short-circuit":"Yes; channel by channel","Weight, approx.":"250 g","lifecycle_stage":"current","Diagnostic alarm":"Yes","Power loss, typ.":"2.5 W","Rated value (DC)":"24 V","Unshielded, Max.":"30 m","On Lamp Load, Max.":"1 Hz","up to 20 °C, max.":"6 A","up to 55 °C, max.":"4 A","Between The Channels":"No","Diagnostics function":"Yes; Parameterizable","For Signal \"1\", Min.":"2L+ (-0,8 V)","Group error SF (red)":"Yes","Isolation tested with":"500 V DC","Response threshold, typ.":"3.5 A","Short-circuit protection":"Yes; Electronic","Number of digital outputs":"4","With Inductive Load, Max.":"0.5 Hz","With Resistive Load, Max.":"100 Hz","Between Different Circuits":"75 V DC/60 V AC","For Signal \"1\" Rated Value":"2 A; At 24 V DC","Controlling a digital input":"Yes; at minimum current of 6 mA","Reverse polarity protection":"No","For Redundant Control Of A Load":"Yes; only outputs of the same group","from backplane bus 5 V DC, max.":"40 mA","For Signal \"0\" Residual Current, Max.":"0.5 mA","Between The Channels And Backplane Bus":"Yes","For Signal \"1\" Permissible Range, Max.":"2.4 A","For Signal \"1\" Permissible Range, Min.":"6 mA","Load voltage monitoring 24 V DC (green)":"Yes","Status indicator digital output (green)":"Yes","from load voltage 2L+ (without load), max.":"60 mA","Limitation of inductive shutdown voltage to":"2L+ (-53 V)","Between Backplane Bus And All Other Circuit Components":"Yes","Between Load Voltage And All Other Switching Components":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$920.75","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/eaa2d09cb181f4f534f179bc0da588d0.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=486476&mlfb=6ES7148-1CA00-0XB0"},"ai":{"faq":[{"question":"Where to buy 6ES7148-1CA00-0XB0?","answer":"Submit an RFQ for current availability and pricing — no stock-holding claim, no deferred lead-time figure."},{"question":"Does 6ES7148-1CA00-0XB0 support diagnostic interrupts?","answer":"Yes — the module has a parameterizable diagnostic alarm that triggers on wire-break and short-circuit events, channel by channel.
