Operating Instructions

Property Data / explanation
Analog inputs 4 (AI 0 … AI 3)
● Differential inputs
● 12-bit resolution
● 13 ms response time
● AI 0 and AI 1 can be switched over:
– 0 V … 10 V or ‑10 V … +10 V (typical power consumption: 0.1 mA,
voltage < 35 V)
– 0 mA … 20 mA (120 Ω input resistance, voltage < 10 V,
current < 80 mA)
● If AI 0 and AI 1 are configured as supplementary digital inputs: Voltage
< 35 V, low < 1.6 V, high > 4.0 V, 13 ms ± 1 ms response time for
debounce time p0724 = 0.
● AI 2 switchable:
– 0 mA … 20 mA (voltage < 10 V, current < 80 mA)
– Temperature sensor Pt1000/LG-Ni1000/DIN-Ni1000
(characteristics: See below)
● AI 3:
Temperature sensor Pt1000/LG-Ni1000/DIN-Ni1000 (characteristics:
