What it is and what it does
The 6ES7155-6BA01-0CN0: It runs on firmware V4.2 and draws a maximum of 335 mA from the 24 V DC supply, with an inrush current of 1.6 A. I&M data up to I&M3 is supported, along with alarms, diagnostics, SYNC/FREEZE capabilities, and an HW functional status indicator starting from FS02.
Ratings that matter for integration
The I2t rating of 0.038 A²·s sets the thermal energy limit for the module's internal protection – relevant when sizing upstream branch protection to avoid nuisance trips during short-circuit events. Isolation is tested at 707 V DC between circuits (type test), and all circuits are SELV-rated, so safe to use in the same panel as other 24 V equipment without extra isolation barriers. Temperature range depends on orientation: horizontal mounting allows 60 °C ambient, vertical drops to 50 °C. Minimum temperature is -25 °C with no condensation permitted.
Lifecycle and sourcing
Sourcing is straightforward – quoted to order against an RFQ. Tell me the quantity and I can confirm lead time.
