11.1 Technical data of inputs and outputs
Property Explanation
Fieldbus interface With RS485 interface for the following protocols:
● USS
● Modbus RTU
● BACnet MS/TP
24 V power supply The converter generates its 24 V power supply from the line voltage.
Output voltages
● 24 V (max. 250 mA)
● 10 V (max. 10 mA)
Setpoint resolution 0.01 Hz
Digital inputs 6 (DI 0 … DI 5)
● Electrically isolated only when supplied via an external isolated 24V supply
● Type 3 in accordance with EN 61131-2
● Voltage for "low" state: < 5 V
● Voltage for "high" state: > 11 V
● Current for 24 V input voltage: 4 mA
● Minimum current for the "high" state: 2.5 mA
● 30 V maximum input voltage
● PNP/NPN switchable
● Compatible to SIMATIC outputs
● 10 ms response time for debounce time p0724 = 0
Analog inputs 2 (AI 0 ... AI 1)
● Single-ended input
● 12-bit resolution
● 13 ms response time
● Switchable between voltage and current via parameter setting:
– -10/0 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
● 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.
Digital outputs 4 (DO 0 ... D0 3)
● DO 0 ... DO 3: 250 V AC 1A/30 V DC 1A, for resistive, inductive or
capacitive load
● 1 type C relay, 3 type A relays
● Update time: 2 ms
● Max. 1 A (with ambient temperature ≤ 60 °C)
● Overvoltage category: II
● Switching cycle: 1 Hz
