Description of Functions
3-15
3.2.3 Digital outputs
The binary outputs can be used as follows:
• Signalling of successful/failed messages, see Section 4.6 Alarm
Message and 4.9 Function control.
• Remote-switching via telephone using tone dialling, see below
• Switching from another IE-GPRS-I/O of a group via X-Rec, see
Section 4.4 Digital inputs and outputs (Digital I/O) Digital outputs
• Operating voltage: 10 … 30 VDC
Output current: max. 400 mA
• Number: 4
The short-circuit and overload protection of the outputs must be
provided by external measures.
Remote-switching:
• Call the IE-GPRS-I/O using a telephone or mobile telephone.
• Enter the PIN (see Section 4.3 Access to the device).
• Press a number for the number of the output: 1 … 4
• Switching command, key 0 = OFF or 1 = ON.
When remote-switching, be especially cautious and work with
special care, as you cannot observe the reaction of the connected
plant from a distance. You should only switch an output if you are
fully informed as to all effects resulting for the plant. Make
absolutely sure that the health and safety of persons is not
endangered.
