Siemens 6ES7134-4NB51-0AB0 is a 2-channel analog input module for the ET 200S system, 15 mm wide. It uses integrating sigma-delta measurement with configurable integration time of 16,7 / 20 ms. Power is drawn from the backplane at 24 V DC, with a typical loss of 0.6 W. No isochronous mode support. Group diagnostics, wire-break detection, and overflow/underflow can be enabled per channel. Isolation tested at 500 V DC. Maximum shielded cable length is 200 m.
