2 analog inputs for 4-wire transducers
The Siemens 6ES7134-4GB60-0AB0 is a SIMATIC DP electronic module for the ET 200S distributed I/O system, providing 2 analog inputs for 4-wire transmitters with a 4 to 20 mA signal range. It delivers a 12-bit resolution with overrange and a per-channel conversion time of 0.1 ms, giving a module cycle time of 1 ms for all channels — fast enough for most process-value updates on a packaging or material-handling line.
Diagnostics and signal conditioning
Built-in wire-break detection and group diagnostics (red SF LED) are individually enable/disable per channel, so you can suppress nuisance alarms on unused inputs while keeping fault coverage on active loops. Overflow/underflow detection is also configurable per channel, and the module reports a group error when any enabled diagnostic trips. The input circuit is isolated between channels and the backplane bus, but there is no isolation between the channels themselves — keep that in mind if your two loops share a common reference that could differ in potential.
Power budget and wiring reach
The module draws its 24 V DC from the ET 200S power module, consuming 35 mA max from the load voltage L+ (unloaded) and 10 mA from the 3.3 V backplane bus. Shielded cable runs up to 200 m are permissible; the destruction limit for the current input is 35 mA, so a shorted loop will not immediately damage the input stage.
