2-Channel Analog Input for ET 200S
This Siemens 6ES7134-4GB61-0AB0 is a 2-channel analog input module for the ET 200S distributed I/O system, accepting both 4-to-20 mA and bipolar -20 to +20 mA signals. Per-channel conversion time is 0.1 ms with a maximum cycle time of 1 ms per module, suitable for closed-loop control or fast monitoring applications. Diagnostics include parameterizable wire-break and group error detection, with a group error SF (red) LED for immediate fault indication. The module draws 90 mA from the backplane bus for both channels and dissipates 0.8 W typ., fitting the ET 200S power budget without surprises.
Mounting & Wiring
Width of 15 mm and depth of 52 mm match the standard ET 200S profile rail footprint; install in any slot of an interface module. Shielded cable run up to 200 m; supply voltage is 24 V DC from the power module, with L+ output under load dropping to -2.5 V. Input resistance is 0.05 kΩ for the 0 to 20 mA range; reverse polarity protection and electronic short-circuit protection are built in. Parameterizable digital filtering in four stages and isochronous mode allow tuning response time versus noise rejection.
Production Status & Sourcing
Available to order; the listed dimensions and electrical ratings are directly from the official Siemens documentation.
