It measures current (up to 4 channels) and voltage, calculates power and energy, and flags limit-value alarms or hardware interrupts on up to 16 selectable process values. Supply is 24 V DC from the backplane; no external power needed. Firmware is V8.0 out of the box, and the module supports I&M data (I&M0–I&M3) plus online firmware update. ## Mechanical Fit & Integration Width 20 mm, depth 58 mm, height 73 mm — occupies a single ET 200SP slot. It requires a BU type U0 base unit (order separately). Shielded or unshielded cable runs up to 200 m per channel. Input resistance is 120 kΩ; power loss typ. 400 mW at 230 V AC. ## Diagnostics & Commissioning Standard diagnostics include line quality analysis, voltage swell/dip detection, overflow/underflow, and overload current monitoring. A diagnostic alarm or hardware interrupt can be assigned to any of 16 process thresholds. Automatic encoding means the module self-identifies on the backplane — no DIP-switch mapping. For FAT/SAT, the parameter length is 128 bytes and the I&M data helps track module history.","metaTitle":"Siemens 6ES7134-6PA21-0CU0 ET 200SP Module, 24 V DC, 20 mm","metaDescription":"Current lifecycle ET 200SP analog input/energy module. 58 mm depth, 20 mm width, firmware V8.0.
