SM 336 F-AI HART analog input module

The safety-related SM 336 F-AI HART analog input module has 6 inputs for current measurements in the range from 0 to 20 mA or 4 to 20 mA, all of which are designed for SIL 3. The compact width of 40 mm means that a relatively high packing density can be achieved for F modules, allowing a design which saves space and costs.

The module can also handle HART communication with appropriate HART field devices. HART communication can be activated safety-related in online mode, or switched off.

Digital output module SM 326 F-DO

The 40-mm wide safety-related SM 326 F‑DO digital output module with 10 outputs (24 V DC, 2 A) and parameterizable redundancy extends the range of compact F‑modules commenced with the SM 336 F‑AI HART. The module features short response times, and can be used in SIL 3 applications even without an isolating module. It supports the "Keep last valid value" function as well as channel-selective passivation.
