The Siemens 6ES7134-4GB01-0AB0 is an active SIMATIC DP electronics module for ET200S, providing 2 analog current inputs accepting 4 to 20 mA with 13-bit resolution. The 15 mm width lets you pack dense channel counts on the rail. Each channel converts in 65 ms with selectable integration times for 50/60 Hz suppression, and the module includes a group error SF LED, wire-break detection, and four-stage digital filtering that you can parameterize via the engineering tool.
Diagnostics and filtering
Diagnostics cover wire-break, group error, and overflow/underflow, each individually enable/disable. Filtering steps let you slow the response to 4×, 32×, or 64× the base cycle time, which is handy when you need to damp electrical noise on the loop without adding external signal conditioners. Reverse polarity protection limits the destruction current to 35 mA per channel, and the module draws power from the backplane bus (24 V DC, 80 mA max from load voltage), so no separate loop supply is required for standard 2-wire transmitters.
