Input
|
| Type |
4 to 20 mA with ≤ 2.5 V voltage drop, reverse polarity protected in normal operation, ≥ 5 kΩ impedance (≈ 2 mA sinking from 10 to 30 Vdc) when fault condition detected. |

|
| Type |
4 to 20 mA, on max. 700 Ω load. |
| Response time |

Fault
|
| Type |
Field device and wiring open circuit or short circuit detection; short circuit detection can be disabled via dip-switch. |
| Short output |
load resistance < 50 Ω or < 100 Ω dip-switch selectable (≈ 2 mA forcing to detect fault). |
| Open output |
load resistance > (21 V / Loop current) -300 Ω (for example, if Loop current = 20 mA: load resistance > (21 V / 20 mA) -300 Ω = 750 Ω). |
| Fault signaling |

100 mA @ 35 Vdc (≤ 1.5 V voltage drop). |
| Leakage current |
≤ 50 μA @ 35 Vdc. |
| Response time |
≤ 30 ms. |
