10.1 Technical data of inputs and outputs
Feature Data
24 V power supply There are two options regarding the 24 V supply.
● The inverter generates its 24 V power supply from the line voltage
● The inverter obtains is 24 V power supply via terminals 31 and 32 with 20.4 … 28.8 VDC.
Typical current drain: 0.5 A
Output voltages
● 24 V (max. 100 mA)
● 10 V ± 0.5 V (max. 10 mA)
Setpoint resolution 0.01 Hz
Digital inputs
● 6 digital inputs, DI 0 … DI 5, 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. 5.5 ms ± 1 ms
Analog input (differ‐
ential input, 12-bit
resolution)
● AI 0 switchable:
– 0 V … 10 V or ‑10 V … +10 V: Typical current drain: 0.1 mA, maximum voltage 35 V
– 0 mA … 20 mA: Maximum voltage 10 V, maximum current 80 mA
● Response time: 10 ms ± 2 ms
● If AI 0 has been configured as additional digital input:
Maximum voltage < 35 V, low < 1.6 V, high > 4.0 V, 13 ms ± 1 ms response time for debounce
time p0724 = 0.
Digital outputs /re‐
lay outputs
● DO 0: Relay output, 30 V DC / ≤ 0.5 A for resistive load
● DO 1: Transistor output, 30 V DC / ≤ 0.5 A for ohmic loads, reverse polarity protection.
● Output current from DO1 for "low" state: ≤ 0.5 mA
● Update time of all DO: 2 ms
Analog output
● AO 0 switchable:
– 0 V … 10 V
– 0 mA … 20 mA
– 16-bit resolution
– Update time: 4 ms
