2 analog inputs, ±10 V, 13-bit — IP67 field module
The 3RK1207-2BQ00-0AA3 is a Siemens AS-Interface compact module in the K60 form factor, providing two analog inputs for voltage measurement with a ±10 V range and 13-bit A/D resolution. The 4-conductor M12 connections support 2-wire sensors on active channels 1 and 2. The IP67 rating means it can be mounted directly in wet or washdown zones without an enclosure — the module body and M12 connectors are sealed against hose-directed water. Power comes from the AS-Interface bus (26.5–31.6 V) plus a separate auxiliary sensor supply Uaux (24–30 V). The module draws up to 500 mA from Uaux; without Uaux the draw drops to 46 mA.
Mounting and panel fit — K60 compact module
The K60 module measures 60 mm wide by 152 mm high by 29 mm deep. It snaps onto standard DIN rail or mounts to a wall using the separate mounting plate 3RK1901-0CA00 (ordered separately). Operating temperature range is 0 to 60 °C; storage range is -40 to +85 °C.
