Power supply concept
According to ignition protection requirements the following power supply
systems are available:
For standard applications outside Ex-zones SECU-DATA xxxx is supplied
from a standard DC supply
According to ignition protection requirements the following power supply
systems are available:
For standard applications outside Ex-zones SECU-DATA xxxx is supplied
from a standard DC supply
in the range of +11 V … +40 V. If the transmitter
and/or the receiver are installed in Ex-zone 1 a SECU-BAR 125 barrier has
to be inserted in between to achieve intrinsic safety as per EN 60079-11.
Radio frequency data transfer
Transmitting and receiving frequency in the 433 MHz band, very narrow
bandwidth, 64 channels in 8 frequency blocks (selectable on the instru-
ment), 25 kHz channel separation, effective range up to 1 km or even more
in open areas, best temperature stability, insensitive to distortions, automat-
ic selection of an undistorted channel, RF data transmission rate: 4.800
Baud (data bits/s, the effective data rate is 2.400 Baud). Data loss is pre-
vented by using a CRC16 error correction.
A potential-free relay contact is used to monitor the status of the RF con-
nection, e.g. to issue an alert in case of an RF interruption
