Analog terminals
Terminal Application / electrical data
AU/AI Voltage or current input
General data:
Resolution: 10 bits
(Error: 1 digit ≡ 0.1 %, in relation to the final value)
Conversion rate: 1 kHz
In order to filter short-time faults in the analog signal char-
acteristic, the analog input value is led via a digital lag filter
with a time constant of 5 ms.
Processing cycle: 1 kHz (1 ms)
Electric strength of external voltage ±15 V, permanent
Temperature influence: ±0.5 % or ±1 mV/K
(T
amb
= -10 °C ... +55 °C)
When being configured as voltage input ( C00034 = "0")
Level/scaling: 0 ... +10 V ≡ 0 ... +2 14 ≡ 0 ... +16384 ≡ 0 ... +100 %
Input resistance: > 80 kΩ
Input voltage in case of open circuit: Display 0 (U < 0.2 V, abs.)
Accuracy: ±0.1 V
Limit frequency: 315 Hz at -3 dB
When being configured as current input ( C00034 = "1" or "2")
Level/scaling: When C00034 = "1":
0 ... +20 mA ≡ 0 ... +2 14 ≡ 0 ... +16384 ≡ 0 ... +100 %
When C00034 = "2" (life-zero):
+4 ... +20 mA ≡ 0 ... +2 14 ≡ 0 ... +16384 ≡ 0 ... +100 %
Switching hysteresis: 1 % (at 20 mA)
Input resistance: approx. 250 Ω
Input voltage in case of open circuit: Display 0 (I < 0.1 mA)
Accuracy: ±0.1 mA
AR 10-V reference voltage
Output current: max. 10 mA
GA Reference potential (analog ground, GND)
