MOOGMoog GmbH Hydraulic Controls Engineering (HCE) User Manual Control System QAIO 2/2 AV Analog Extension Module with Pulse Input

Current output 4–20 mA: ≤ 500 Ω 

The load impedance range of the current output 4–20 mA does not comply with IEC 61131-2. 

(IEC 61131-2 requires a load impedance range of ≤ 600 Ω.) 

Update time 

The update time corresponds to the task interval of the application program 

that actuates the output. 

The task interval (and thereby the update time of the outputs) is set in the task configuration of 

the MACS development environment. 

Rise time T10/90

Rise time T10/90 of QAIO 2/2 Analog Outputs Protection Continuous short-circuit protection; overvoltage protection up to ±36 V Short-circuit current IKmax Voltage output ±10 V: IKmax = ±15 mA Current output ±10 mA: IKmax = ±10.92 mA Current output ±50 mA: IKmax = ±54.61 mA Current output 4–20 mA: IKmax = ±20.74 mA

Recommended cable types 

Use only shielded cables. 

The shield must be made of copper braiding with at least 80% coverage. 

The wire must be made of copper with a cross section of at least 0.25 mm2 (23 AWG). 

In environments with a high amount of disturbance, use cables with twisted pair wires. 

Calibration 

The QAIO 2/2 is calibrated at the factory and does not require any additional 

calibration. 

Permissible load types 

Resistive load according to "Load impedance range" 

The stability of the current outputs is ensured up to an inductive 

load of 100 mH. 

The stability of the voltage outputs is ensured up to a capacitive 

load of 10 µF. 

Output current of the voltage output 

Max. 10 mA 

Wire fault monitoring of the analog current outputs 

The analog current outputs are monitored for wire faults. The status of the wire fault monitoring can 

be evaluated in the application program.
