This is an AS-Interface sensor/actuator module designed for use in switch cabinets, featuring 4 inputs and 4 electronic outputs, with a housing width of 19 mm for DIN rail mounting.
Can the supply to the sensors be selected?
Yes, the supply to the sensors can be either from the internal supply of the module from the AS-Interface or via an external voltage source, selectable via a switch on the module.
What are the indicators available on this module?
The module includes LED indicators for bus, external auxiliary voltage, internal sensor supply, inputs, and outputs, with a red LED per channel that lights up in the event of output overload.
Is the module suitable for safety applications?
The module offers safe galvanic isolation between the output part supplied by AUX and the other circuit components, making it suitable for applications requiring reliable switch-off of the AUX power supply for EMERGENCY STOP functions up to safety classification PLd.
What is the function of the communication monitor on this module?
The communication monitor deactivates the outputs if the AS-Interface does not communicate with the module for more than 40 ms. This feature ensures reliable operation and can be deactivated via parameter P0 if necessary.
How are the inputs and outputs connected?
Connections are made via removable 4-pin push-in terminal blocks, which are mechanically coded to prevent incorrect wiring. The terminal blocks for AS-i+, AS-i-, AUX+, and AUX- have bridged connections.
What type of protection does the module offer?
The module is designed with a degree of protection IP20 and requires installation in an enclosure with a minimum protection class of IP54 for safety applications. It also includes surge protection for the auxiliary voltages and AS-Interface voltage.
Can the module detect lead breakage and overload?
Yes, the module can detect and report a missing load or overload condition via the OUT LEDs and the 'peripheral fault' function, which communicates the issue to the AS-Interface master.
What are the ambient conditions suitable for the module?
The module can operate in ambient temperatures ranging from -25 to 70 °C and should be used indoors only. It's also designed to withstand certain levels of shock, impact, and vibration.
What are the electrical specifications for the inputs and outputs?
The inputs are for 3-wire sensors (PNP), DC, with a supply from AS-Interface or external voltage. The outputs are electronic, PNP, overload and short-circuit proof, supplied from an external auxiliary voltage.
