Power draw sits at 1.5 W typ., with 15 mA from the backplane bus, leaving headroom for adjacent modules in the S7-1200 rack.
Ratings and tolerances
Temperature error is held to ±0.5% at 25 °C and ±1% up to 55 °C, and the module can be installed at altitudes up to 5 000 m with appropriate derating above 2 000 m. The 21 mm width and 62 mm height keep it to a single SB slice size; it mounts directly on the S7-1200 DIN rail without extra wiring changes. For field service: the module includes diagnostics function and alarm output, so a quick status read from the CPU tells you if the output channel is open or shorted.
This is a signal-output module for a Siemens S7-1200 controller, intended for analog control loops in machines or processes where standard modules can't handle the atmosphere — think coolant mist, diesel fumes, or salt spray. Conformal coating (Class A) and Type 1 protection against fouling suit this module for lube-skid panels, compressor packages, and outdoor installations near rotating equipment.
