Terminal strip
Fig. 3-1 Terminal strip of the MIQ/JBR
On the terminal strip inside the enclosure, the MIQ/JBR has four SENSORNET
connections. Two of these connections are assigned to each of the signal
ranges (section A, section B) in the IQ S
ENSOR
N
ET
.
Outside contacts The outside contacts on the back and front side of the module enclosure are
connected with section A. Thus, all modules connected to the MIQ/JBR by stack
mounting are connected to section A.
A module can only be connected to section B via the 2 SENSORNET
connections for section B on the terminal strip.
Power supply For power supply purposes, the IQ S
ENSOR
N
ET
system is always regarded as
one undivided system. Determine the number of MIQ power supply modules
required for the system following the rules for the optimum power supply (see
system operating manual).
Signal
amplification
To amplify the signal, the MIQ/JBR divides the IQ S
ENSOR
N
ET
into signal
ranges (section A, section B).
Within a signal range, the overall cable length (SNCIQ IQ S
ENSOR
N
ET
cables
+ SACIQ sensor connection cables) must not be more than 1000 m. In an
IQ S
ENSOR
N
ET
system, up to two signal amplifier modules may be installed.
