The Siemens 6ES7134-4GB50-0AB0 is a SIMATIC DP electronic module providing 2 analog inputs for the ET 200S distributed I/O system. It accepts 4 to 20 mA signals from 2-wire transducers, with a 12-bit resolution including sign bit and a conversion time of 0.1 ms per channel. The module's cycle time across both channels is 1 ms max, making it suitable for applications where fast loop updates matter — think flow or pressure control loops that need sub-millisecond response.
Power and diagnostics
The module draws its 24 V DC supply from the ET 200S power module — no separate power wiring needed. Typical power loss is 0.8 W. It pulls up to 35 mA from the load voltage L+ (without load) and 10 mA from the backplane bus at 3.3 V DC. Group diagnostics (SF red LED) can be enabled or disabled, as can per-channel wire-break and overflow/underflow detection. Isolation exists between channels and the backplane bus, but not between channels themselves or between channels and load voltage L+.
This part carries a current lifecycle status from Siemens. It is designated as a spare part for existing ET 200S installations — not a current-series product for new designs. The ET 200S platform has been superseded by ET 200SP and ET 200AL, but for installed-base maintenance this module remains available through independent distribution.
