The Siemens 6ES7134-4MB02-0AB0 is a 2-channel analog input module for the ET 200S distributed I/O system, accepting 4-20 mA as well as bipolar -20 to +20 mA signals with 16-bit sigma-delta conversion. Rated supply voltage 24 V DC, with power loss typical 1.2 W. Up to 10 mA drawn from the backplane bus; load current from L+ up to 48 mA.
Diagnostics and features
Wire break detection is available but only when the measuring range is set to 4 to 20 mA. Group diagnostics and hardware interrupts are parameterisable, as are overflow/underflow and diagnostics enable/disable. Isochronous mode is supported. Conversion time per channel: 0.04 ms without noise suppression, or 17/20 ms per channel with 60/50 Hz interference suppression. Cycle time for both channels max 0.5 ms without suppression, 18 or 21 ms with. The module is short-circuit proof and features reverse polarity protection. Galvanic isolation between channels and backplane bus, and between channels and load voltage L+.
