Weidmuller IE-GPRS-I/O - Manual (Page 2)

The IE-GPRS-IO Alarm Modem is suitable for use in applications requiring signals to be
activated via relay contacts, limit values to be monitored in analogue mode or where hig-
her-level systems are to receive data per serial protocol.
A virtual dedicated line can be configured via GPRS. Thus point-to-point, multipoint,
multidrop topologies can be created extremely economically and with optimum functio-
nality.
'Transparent RS-232 data transmission via GPRS'
The IE-GPRS-IO is designed to transmit the widely varying status signals generated
from within a facility, the begin or end of a control procedure or alarm signals as well as
other information as required.
That means the IE-GPRS-IO can be integrated into legacy installations.
The devices are equipped with 1 serial interface and 2 x 4 digital inputs, 2 x 2 digital out-
puts as well as 2 x 2 analogue inputs.
The top-hat style housing contains the microcontroller for acquiring system statuses
and storing the message texts. In accordance with the integrated layer plan function,
messages are issued to up to 8 target numbers per signal input. The operating or bias
current principle can be selected.
The device is fitted with LEDs for diagnostics and status indication. The device can send
messages as sms, acknowledgement, fax, e-mail, pager or direct call.
