Key ratings and what they mean for fit
The 6AG1134-4GB52-2AB0: Two analog inputs with a resolution of up to 16 bits (parameterizable). Input resistance is 106 Ω for 0-20 mA range. The module supports diagnostics including wire-break detection at 4-20 mA, group error, overflow/underflow, and hardware interrupts. Short-circuit proof and reverse polarity protected per channel, but without inter-channel isolation. Cycle time for all channels is 0.25 ms maximum, suitable for high-speed data capture. Address space per module is 4 bytes. Isochronous mode is supported for deterministic update rates. Operating temperature range -25 °C to 60 °C with installation altitude up to 5 000 m above sea level. The CE mark is listed; no other certifications appear in the spec sheet.
Mechanical and integration
Dimensions are 15 mm width, 81 mm height, 52 mm depth. The narrow width allows dense packing on the DIN rail. Shielded cable length maximum 200 m for signal integrity. Wiring details are per standard S7-1200 I/O modules.
