SIPLUS ruggedization for harsh environments
The 6AG1193-6BP00-7DA0: This is not a field-applied coating — the IPC-CC-830A Class A conformal coating is applied during PCB assembly, protecting against condensation, frost, commercially available coolants, lubricants, diesel, and oil droplets in the air. The unit also meets ANSI/ISA-71.04 Level GX Group A/B for corrosive gas environments and Level LC3 salt spray, making it suitable for process, oil & gas, and wastewater applications where standard ET 200SP hardware would degrade.
DIN-rail footprint and bus junction capacity
This BU type A0 base unit occupies a single slot (15 mm width × 117 mm height × 35 mm depth) on the DIN rail, accepting one ET 200SP I/O module with push-in terminals — no AUX terminals, no extra load group. External protection for the 24 V DC supply lines should be a 10 A miniature circuit breaker with type B or C tripping characteristic per the manufacturer's specification.
