It accepts 256 bytes of input data and delivers 20 bytes of output data, communicating over the ET 200SP backplane at firmware V8.0. ## Kit completeness check The module is supplied alone. For operation it requires a BU type U0 BaseUnit (2-wire connection), ordered separately. Verify the BaseUnit is on hand before the slot is assigned — no holes in the box. Mechanical footprint: 58 mm depth x 20 mm width x 73 mm height, fitting any mounting position. Wiring to the BaseUnit supports shielded or unshielded cable runs up to 200 m, terminated through the spring-cage connectors on the BU type U0. ## Lifecycle & sourcing posture This is the module to specify for new builds or spares, with firmware V8.0 as the current revision. Sourced to order; RFQ for lead time and availability. Diagnostic alarm, limit value alarm, and hardware interrupt with monitoring of up to 16 freely selectable process values give real-time fault visibility. The module supports isochronous mode? No — isochronous mode is not supported, so it is not suited for cycle-synchronous applications demanding T1 deterministic updates. Rated supply 24 V DC, drawn from the backplane bus via the BaseUnit. Typical power loss is 400 mW, leaving margin for dense modules on the same segment. Overvoltage category CAT II per IEC 61010-1, with a maximum secondary-side voltage of 300 V. Input resistance 120 kΩ per channel.","metaTitle":"Siemens 6ES7134-6PA21-0BU0 ET 200SP AI Energy, 58 mm","metaDescription":"Active-production Siemens ET 200SP analog input module for power/energy measurement. 256-byte inputs, 24 V DC, 58 mm depth.
