What it is and what it does
The 6AG1055-1MM00-7BA2: This is the wide-temperature, conformal-coated variant of the LOGO! AM2 AQ analog output module for LOGO! 8 controllers. It adds two analog outputs configurable as 0-10 V, 0-20 mA or 4-20 mA, powered at 24 V DC. The module snaps onto a 35 mm DIN rail and occupies 2 spacing units (35.5 mm wide). The SIPLUS designation means it carries a -40 to +70 °C operating range, with cold-start down to -25 °C, and conformal coating that resists commercially available coolants, lubricants, diesel, and oil droplets in the air. Meets environmental conditions for process control with harmful gas, salt spray, and oil resistance.
What the ratings mean for fit
The -40 to +70 °C range covers most industrial environments beyond indoor climate-controlled panels. The -25 °C cold-start minimum (with condensation permitted but not commissioning under condensation) is what matters for refrigerated areas or outdoor winter startups. IP20 means it relies on the enclosing panel for dust and liquid protection — the conformal coating itself handles the internal condensation and chemical exposure, so you don't need an IP54 cabinet just for this module. Installation altitude up to 5 000 m with derated temperature at higher altitudes is specified, so it works in high-elevation installations (Andean, Himalayan, or aircraft ground support) without external derating charts.
Mounting and integration details
Snaps onto standard 35 mm DIN rail, 2 spacing units wide (35.5 mm). No front connector needed — terminals are accessible on the module face. Height 90 mm, depth 58 mm; factor in the clearance for wiring ducts and enclosure depth. Powered from the LOGO! backplane or an external 24 V DC supply. Outputs are configurable per channel via LOGO! Soft Comfort software. No fieldbus or Ethernet interface on this module; the LOGO! controller handles communication.
