Block diagram and isolation policy
All of the green lines in the diagram below denote an isolation barrier. Every block of the TX-L shown is isolated from every other block and from the case.
All of the individual analogue inputs are isolated from each other and from the auxiliary power supplies.
Isolation barriers are to a minimum of 10M Ohms at 1,000V DC.
The thick green lines denote two expansion cards that may be fitted. In this case one analogue and one digital card are shown.
The SA380TX-L is certified for use in Over-voltage CAT III, Pollution Degree 2 environments (as defined in IEC 60664-1) when powered from no more than a 130 V AC supply.
Power supply - AC units only
The “universal input” power supply accepts any voltage from 85 to 264V ac.
