Overview
T1900- is a DIN-rail mounting controller with universal input accepting Pt100, 10
T/C types and various linear signals. It can have up to 3 relays (control or alarm) and
analog output that may be controlled through ON/OFF and self-tuning PID-fuzzy
algorithms as well as optional AMP/SOAK pattern control. A bumpless auto-manual
change-over is also built in the PID algorithm. T1900- is equipped with 4-digit LED
display and 4-button keyboard for programming. A triple input/output/supply isolation
protects the controller from electro-magnetic disturbances. Communication features
include S485 MODEBUS interface and USB port for program parameter storage.
T1900- is well equipped for trouble-free operation in harsh industrial conditions.
Mounting
♦ T1900- can be mounted on
every 33-mm rail confirming EN
50022.
♦ Install T1900- following the
steps 1-2 as shown on the left.
♦ Always observe device
dimensions (W40xH107xD43)
before installation!
♦ Uninstall t1900- using a
suitable screwdriver and
following the steps 1-2 as
shown on the left picture.
♦ If install 2 or more units on the
same rail, use the enclosed
plastic spacer to provide
adequate air cooling distance
following the marks on the left.
Never place units without a
gap (min. 5mm) etween them or
other rail-mounted devices!
It may result in overheating and
device failure!

Electro-Magnetic Interference (EMI) Issues
15
Important note:
RT1900 may content a
RC noise suppression
circuit is connected in
parallel with relay
contacts.
Full AC voltage isolation
is NOT provided when
relay contacts are open.
Small AC current
(≈ 1.5 mA at 230 VAC)
still flows through
the RC circuit!
♦ All signal wires must be shielded. They must
not be packaged together with power cables!
♦ Never lay the signal wires close to inductive or
capacitive noise sources, such as relays,
contactors, motors, etc.!
♦ All shields have to be grounded ONLY at one
end, as closer as possible to device terminals!
♦ Avoid sharing supply lines with powerful
consumers, especially with inductive loads,
switched on and off.
♦ To stop unwelcome interference signals
entering through the power supply lines,
use shielded 1:1 isolation transformer!
♦ Shunt all switched (not only those switched
by the indicator) inductive consumers with
special suppression networks: C group and
varistor - for AC loads, or diode - for DC loads.
♦ If the indicator operates in a very powerful
EMI area, it has to be mounted inside
a grounded metal shielding box!
Declaration of Conformity
We hereby declare that this device has been
manufactured in compliance with standards
EN 61000, EN 61010 and EN 61326,
and meets the requirements of Directives
2004/108/EC, 2006/95/EC and 2011/65/EC.
