Basic specification, Position 1, 2 (Approval) = BG, IG
Power supply and signal circuit with protection type: not intrinsically safe.
Basic specification, Position 3 (Power Supply, Output) = E, G
The power consumption of I/O modules with passive PFS output can be limited for certain
applications.
• Recommended: Power consumption = 1 W. This is obtained for a supply voltage at the terminals of
27 V .
DC
• For higher supply voltages (U
