Indicator – panel meter
This indicator or panel meter (96 x 48 mm,
1/8 DIN, with integrated trend and bargraph
functions) is equipped with universal ana-
logue input (RTD/TC/standard linear inputs)
for the acquisition of process signals with
fast transient (conversion frequency up to
242 Hz /4,2 ms). As the largest part of Pixsys
instrumentation, STR550 integrates in a
single ordering code all the most requested
hardware solutions: 2-relays programmable
for different alarm modes, two analogue
outputs (0...10V and 0/4...20 mA) for fast and
accurate retransmission of process/set-point
values, one Modbus RTU Slave serial port for
interface with PLC/HMI/PC, 2 configurable
digital inputs, useful built-in power supply
24 Vdc/30 mA for loop-powered external
sensors. Software features includes storing
of max. peak/min peak/peak-to-peak values,
‘Totaliser’ function typical for flow control
and ‘Sum’ function for weighing systems.
For configuration and parameters setting, in
addition to standard Pixsys tools (Memory
Card and Labsoftview software), a wireless
Rfid (NFC) channel is provided and can be
used with the new Pixsys RF-Programmer
device for fast and straight-forward pro-
gramming.

Multi-channel device circuit breaker boards
The new multi-channel device circuit breaker boards from Phoenix
Contact are available with 4, 8, and 12 channels.The boards are very
versatile as they can be fitted individually with thermomagnetic or
electronic circuit breakers. They are particularly suitable for machine
building and control and process technology.
Due to the central potential distribution, up to four loads
can be protected per channel.This reduces installation time to
a minimum, while simultaneously saving space compared to
conventional installations. In addition to individual load protec-
tion, the boards give you the option to loop in safety-related
relay contacts.
As such, the affected circuits are integrated into the safety
concept with minimal wiring. In doing so, the switch contacts
of the enabling current paths are protected according to regula-
tions. A supply of up to 60 A can be achieved thanks to the high
current carrying capacity.
