The Quicktester A-QT 15 by Göhringer is connected as a passive participant with the fieldbus system AS-Interface. He works without his own address and conforms to the specification V3.0. The compact diagnostic module reads the traffic on the network and sets a relay contact for each 1 s as soon as it detects a communication error.
Typical errors are the exceeding of the nominal cycle time of the network, telegram repetitions, configuration errors and ground fault. The A-QT15 is designed for installation in control cabinets or distribution boxes with 35 mm DIN rail. It is compatible with AS-Interface Power 24 V. A warning light or a horn can be activated via the potential-free alarm contact. In addition, it is possible to evaluate the alarm contact via the higher-level control.
