It accepts Pt100 and Ni100 RTDs in standard and climate ranges, covering the two most common platinum and nickel sensor types used in HVAC, process, and machine temperature loops. Rated for a -30 °C to 55 °C operating ambient, this module handles both cold storage environments and warm cabinet interiors without forced cooling. The 24 V DC rated supply draws a typical 1.5 W power loss, keeping the thermal load on the backplane low. ## SIL 2 safety-rated temperature measurement This module carries a SIL 2 rating per IEC 62061, meaning it can be used in safety-related control systems up to that integrity level for temperature monitoring. The integrating measurement principle and parameterizable diagnostic alarm (wire-break detection on 4-20 mA and 1-5 V ranges, plus overflow/underflow and limit value alarms) give the safety function the diagnostic coverage it needs. Channel-to-channel isolation is not provided, so the module is best deployed where all field wiring shares a common reference potential — typical in a local machine cabinet rather than across long, separately grounded sensor runs. ## M8 shielded connection and wiring reach The ET-Connection uses a shielded M8, 4-pin connector, which mates directly with pre-terminated M8 cordsets. The shielded cable run is rated for up to 30 m, adequate for most machine-mounted sensor clusters. The encoder supply has per-channel short-circuit protection to M, so a fault on one sensor leg does not take down the other three channels. Dimensions are 159 mm height, 30 mm width, 40 mm depth — a slim profile that fits the ET 200AL form factor. The green LED per channel gives a quick visual on channel status during commissioning or fault-finding. ## Active production, sourced per RFQ","metaTitle":"Siemens 6ES7144-5KD00-0BA0 PLC Module, 4 AI RTD, SIL 2","metaDescription":"Siemens 6ES7144-5KD00-0BA0 PLC Communication Module.
