● DI 0 ... DI 6 and DI 16 ... DI 19
● Electrically isolated
● DI 24 ... DI 27
● Not isolated
● Voltage: ≤ 30 V
● Voltage for "low" state: < 5 V
● Voltage for "high" state: > 11 V
● Current for 24 V input voltage: 2.7 mA ... 4.7 mA
● Minimum current for the "high" state: 1.8 mA ... 3.9 mA
● Compatible to SIMATIC outputs
● Response time for debounce time p0724 = 0. 10 ms
Input frequency ≤ 32 kHz
● Differential inputs
● Resolution: 13 bit (12 bits plus sign)
● Response time: 13 ms ± 1 ms
● 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.
● DO 0 ... DO 2: Relay outputs, 30 VDC / ≤ 0.5 A with
resistive load
For applications that require UL certification, the voltage at
DO 0 ... DO 2 must not exceed 30 VDC referred to ground
potential and must be supplied via a grounded Class‑2‑pow‐
er supply.
● DO 24 ... DO27: Transistor outputs
● Output current: ≤ 0.1 A per output
● Output current for "low" state: ≤ 0.5 mA
● An external power supply is required via terminals 31
and 32
● Update time: 2 ms
● 0 V ... 10 V or 0 mA ... 20 mA
● Reference potential: "GND"
● Resolution: 16 bit
● Update time: 4 ms
