This is a current-production Siemens ET 200SP analog input module — order code 6AG1134-6JF00-2CA1 — sized for RTD and thermocouple loops. It reads Pt100, Ni100, Pt1000, and most common TC types (K, J, T, E, N, R, S, B, C, L, U) with 16 bit resolution including sign, plus PTC with 15 bit. That covers the sensor range you’ll find in process and building HVAC panels.
The 15 mm width per module packs eight inputs onto a standard ET 200SP rail — useful when you’re stuffing density into a retrofitted gland plate. Wire-break detection works channel by channel, so you can flag a field cut without guessing which loop dropped. The group error output gives the CPU a single shot if any channel faults. Cable run matters on site: shielded max 200 m for resistance sensors, but only 50 m for thermocouples. That TC limit means you’ll mount the module closer to the field junction box than you might expect if you’re used to RTD runs. No oversampling onboard, so don’t count on sub-cycle acquisition — this is for stable process values, not fast dynamics.
