Frequently Asked Questions
What are the features of the AS-Interface Sensor With Actuator?
The AS-Interface Sensor With Actuator features a housing with removable, coded terminals, an AS-Interface connection via Power Rail, communication monitoring with turn-off capability, outputs loadable up to 8 A per module, inputs for 2- and 3-wire sensors, an addressing jack, power supply of outputs from external auxiliary voltage, and power supply of inputs from the module. It also includes function display for bus, external auxiliary voltage, inputs, and outputs.
How is the AS-Interface Sensor With Actuator mounted?
The AS-Interface Sensor With Actuator is designed for DIN rail mounting and can be easily installed by snapping onto a 35 mm DIN Rail per EN 50022, with the integrated Power Rail.
Can the terminals of the AS-Interface Sensor With Actuator be maintained while the system is powered?
Yes, the plug-in coded terminals of the inputs and outputs allow for 'online' maintenance, meaning they can be serviced while the system is under power, and they are coded to prevent incorrect connections.
What type of inputs and outputs does the AS-Interface Sensor With Actuator have?
The VAA-4EA-KF2-ZE/E2 module has 4 inputs for 2- or 3-wire sensors (PNP, DC) and 4 electronic outputs. The inputs are supplied from the AS-Interface and the outputs are powered from an external auxiliary voltage.
What happens if communication on the AS-Interface cable is interrupted?
If communication on the AS-Interface cable is interrupted for more than 80 ms, the outputs are de-energised by means of an integrated watchdog. This feature can be disabled by the parameter bit P0.
What should be done if a short circuit occurs in the sensor supply?
If a short circuit occurs in the sensor supply, the AS-Interface master will indicate an error and the module will disconnect from the AS-Interface to protect the system.
What are the environmental operating conditions for the AS-Interface Sensor With Actuator?
The AS-Interface Sensor With Actuator operates within an ambient temperature range of -25 to 70 °C (-13 to 158 °F) and can be stored in temperatures ranging from -25 to 85 °C (-13 to 185 °F).
What is the degree of protection for the AS-Interface Sensor With Actuator?
The AS-Interface Sensor With Actuator has a degree of protection rated at IP20, indicating that it is protected against solid objects larger than 12.5 mm but not against water.
How can the AS-Interface Sensor With Actuator be addressed and programmed?
The module includes a programming jack for address configuration, and it supports profile S-7.F with IO code 7 and ID code F. The parameter bits can be programmed via AS-i to control functions such as communication monitoring.
What are the electrical specifications for the auxiliary voltage and operating current?
The auxiliary voltage for the outputs is 20 to 30 V DC PELV, and the rated operating voltage from the AS-Interface is 26.5 to 31.6 V. The rated operating current is less than or equal to 50 mA without sensors and a maximum of 200 mA.
