The Siemens 3RK1107-0BE00-2AA2 is a Slimline Compact I/O module for AS-Interface networks, designed as a standard slave with profile S-7.3.5. It provides two analog outputs with 12-bit resolution, configurable across multiple signal ranges: 0 to 20 mA, 4 to 20 mA, ±20 mA, 1 to 5 V, 0 to 10 V, and ±10 V. The module requires an auxiliary external feed (AUX POWER) of 20 to 30 V DC, compliant with IEC 60990 (PELV), protection class III, to supply the output circuits. Outputs can be powered either from the AS-Interface bus or from this auxiliary supply. It operates on an AS-Interface voltage of 18 to 31.6 V and supports AS-i Power24V. The slave address is set via a front addressing socket, and the ID1 code is factory-set to 'F' but changeable.
The module measures 22.5 mm wide, 100 mm high, and 120 mm deep — a 22.5 mm footprint that fits standard DIN-rail enclosures. Wiring uses screw terminals. Solid conductors: 1x 0.5 to 2.5 mm² or 2x 0.5 to 1.5 mm². Finely stranded with ferrule: 1x 0.25 to 2.5 mm² or 2x 0.25 to 1.0 mm². Stranded without ferrule and AWG stranded are not permitted.
Shock resistance is 15g for 11 ms on the module alone, or 10g for 11 ms with the device connector attached. The module draws up to 200 mA from the AS-Interface bus at 30 V, and up to 200 mA at 24 V with AS-i Power24V. The auxiliary supply can deliver up to 4 A total for the output circuits. The AS-Interface bus itself supplies up to 2 A. The symmetrical temperature error is 0.01 %/K relative to the input or output range, which keeps analog drift low across the operating temperature span.
For a BOM line or a line-down replacement, the fit is confirmed by the AS-Interface profile S-7.3.5 and the 22.5 mm Slimline form factor. The module is parameterizable for output variable type, so it can be configured to match the existing analog output signal range in the application.
