Siemens SIPLUS 6AG1134-4GB11-2AB0 – 2-Channel Analog Input Module
This SIPLUS module gives you two analog inputs, configurable for 4 to 20 mA (with 50 Ω burden) or ±20 mA ranges. Rated for 24 V DC from the S7-1200 backplane, pulling just 0.6 W typical. It works across -25 °C to 60 °C ambient, so it fits in unheated cabinets or plant-floor panels without derating. Dimensions are 15 mm wide, 81 mm high, 52 mm deep – slim enough for high-density layouts. Conversion time per channel is 65 ms (55 / 65 ms variant), and the module supports digital filtering in four stages to smooth noisy process values. Parameterizable via the engineering software. Compliance is covered: CE marked and UL approved, so it clears panel certification for export or UL 508A builds.
Field Wiring and Diagnostics
Shielded cable runs up to 200 m are allowed – that sets the maximum distance from the sensor. Wire-break diagnostics are only available when the input is configured to the 4 to 20 mA range; it won't trigger in ±20 mA mode. Group error (SF red LED) and wire-break, overflow/underflow, and group diagnostics can be enabled or disabled individually. The module does not support isochronous mode. Isolation is tested to 500 V DC between channels and the backplane bus.
