Product details

What this SIPLUS serial module brings to a harsh panel

The Siemens 6AG1138-4DF01-7AB0 is a SIPLUS ET 200S EM 1SI with conformal coating, operating from -25 °C to 70 °C. It occupies a 15 mm slice, draws up to 120 mA from 24 V DC, and includes reverse-polarity protection.

Why the coating and temperature range matter out in the grease

The conformal coating and environmental rating cover gas, salt, and oil contamination (Level GX, LC3, LB3). At sea level, the module operates up to 70 °C.

Frequently asked questions

What compliance documentation is available for this module?

The module meets ANSI/ISA-71.04 environmental conditions for gas, salt, and oil contamination (Level GX, LC3, LB3) and includes conformal coating per IPC-CC-830A Class A.
