11.1 Technical data of inputs and outputs
Feature Data
24 V power supply There are two options regarding the 24 V supply.
• The converter generates its 24 V power supply from the line voltage
• The converter obtains is 24 V power supply via terminals 31 and 32 with 20.4… 28.8VDC.
Typical current consumption: 0.5A
Output voltages
• 24 V (max. 100mA)
• 10V ± 0.5V (max. 10mA)
Setpoint resolution 0.01Hz
Digital inputs
• 6digital inputs, DI0…DI5, isolated;
• Voltage: ≤ 30V
• Voltage for "low" state: <5V
• Voltage for "high" state:>11V
• Current for 24V input voltage: 2.7mA… 4.7mA
• Minimum current for the "high" state: 1.8mA… 3.9mA
• Compatible to SIMATIC outputs
• Response time for debounce time p0724=0: 5ms
Analog input (dier‐
ential input, 12-bit
resolution)
• AI0 switchable:
– 0V…10V or ‑10V…+10V: Typical current drain: 0.1mA, maximum voltage35V
– 0mA…20mA: Maximum voltage10V, maximum current80mA
• Response time: 10ms±2ms
• If AI0 has been congured 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 /relay
outputs
• DO0: Relay output, 30 V DC / ≤ 0.5 A for resistive load
• DO1: Transistor output, 30VDC / ≤ 0.5A for ohmic loads, reverse polarity protection.
• Output current from DO1 for "low" state: ≤0.5mA
• Update time of all DO: 2ms
Analog output
• AO0
– 0V…10V or 0mA…20mA
– 16-bit resolution
– Update time: 4ms
– <400mV oset at 0%
