The Siemens 6ES7134-4JB00-0AB0 is a 2-channel analog input module for the ET 200S distributed I/O system, built for thermocouple types B, E, J, K, L, N, R, S, T plus ±80 mV to ±1 V voltage ranges. Power comes from the backplane at 24 V DC — no separate supply on the slice. The 15 mm width keeps the rail count tight.
Field-service fast swap
A failed module pulls straight off the backplane — no screws. Replacement module takes the same bus connector and terminal block. Power draw is just 0.6 W typical, so backplane capacity isn't taxed even in a dense string of slices.
