Analog input slice for the ET 200SP
The 6ES7134-4FB51-0AB0: 2-channel analog input module for the ET 200SP system. Captures voltage signals from ±10 V down to 1–5 V at 0.1 ms conversion time per channel. Cycle time for all channels max 1 ms, with isochronous mode for synchronized acquisition.
Parameterizable digital filtering
Filter set to one of four stages — none (1× cycle time), low (64×), medium (128×), high (512×). Low or high delay trades noise rejection against response time. For steady-state signals (e.g., temperature, level), medium or high filtering cleans up the acquired value. For transient capture or fast control loops, low or none preserves the edge.
Diagnostics and interrupt capability
Group diagnostics (SF red LED) can be enabled or disabled per channel. Hardware interrupt is parameterizable, as is overflow/underflow detection. Reverse polarity protection on the supply, and isolation tested at 500 V DC.
