根据现场电源可选以下两种P+F隔离栅
**1、KFA5-SOT2-Ex2---115Vac供电
2-channel, Control circuit EEx ia IIC, Reversible mode of operation, 1 passive transistor output, depolarized per channel, EMC acc. to NAMUR NE 21, LB/SC monitoring, Up to SIL2 acc. to IEC 61508, up to SIL3 for a redundant structure, Input: NAMUR sensor, Rated voltage: 103.5 ... 126.5 V AC, Output: Optocoupler, SIL/IEC 61508, Explosion protection: Ex-Input

**2、1、KFA6-SOT2-Ex2---220Vac供电
2-channel, Control circuit EEx ia IIC, Reversible mode of operation, 1 passive transistor output, depolarized per channel, EMC acc. to NAMUR NE 21, LB/SC monitoring, Up to SIL2 acc. to IEC 61508, up to SIL3 for a redundant structure, Input: NAMUR sensor, Rated voltage: 207 ... 253 V AC, Output: Optocoupler, SIL/IEC 61508, Explosion protection: Ex-Input
