What the module is and where it drops in
The Siemens 6ES7136-6AB00-0CA1 is a SIMATIC ET 200SP analog input module on the ET 200SP distributed I/O platform, designed to land on a BU type A0 or A1 BaseUnit and serve safety-related signal acquisition when paired with an S7-300/400F CPU. Lifecycle stage is current.
What the headline ratings actually buy you
The analog input range covers 0 to +10 V, with cyclic measurement and an average value filter available, while MSI (simultaneous mode) is not supported on this variant. Encoder and channel supply is rated up to 300 mA total current of all encoders / channels — the package ceiling, not a per-pin figure. Typical power dissipation is 2 W, fed from a 24 V supply on L+ with the module tolerating a minimum of L+ minus 1.5 V. Galvanic isolation is type-tested at 707 V DC. Shielded field wiring is permitted up to 200 m between the field device and the BaseUnit, which is the practical ceiling for laying this module out on a plant floor.
Diagnostics and channel indication
Channel-level diagnostics include a red ERROR LED per channel, a green channel-status LED, and wire-break detection at the analog front end, so an open sensor leads on the field shows up at the module face and as a diagnostic alarm in the CPU. Module-level diagnostics ride on a green/red DIAG LED, with I&M0 through I&M3 identification data and firmware-update capability supported. The module is parameterizable and supports automatic encoding on the BaseUnit; oversampling is not present on this variant. A limit-value alarm per channel is not provided; alarm behavior here is the diagnostic alarm, not a high/low threshold.
Footprint, BaseUnit pairing, and panel-side notes
Process-image footprint is 14 bytes of inputs and 5 bytes of outputs as a standard module, dropping to 13 bytes of inputs and 4 bytes of outputs when addressed by an S7-300/400F CPU, which is the layout to reserve in the I/O map.
