Overview
3
RT1900-R 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 RAMP/SOAK pattern control. A bumpless auto-manual
change-over is also built in the PID algorithm. RT1900-R 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 RS485 MODEBUS interface and USB port for program parameter storage.
RT1900-R is well equipped for trouble-free operation in harsh industrial conditions.
Mounting
♦
RT1900-R can be mounted on
every 33-mm rail confirming EN
50022.
♦
Install RT1900-R following the
steps 1-2 as shown on the left.
♦
Always observe device
dimensions (W40xH107xD43)
before installation!
♦
Uninstall Rt1900-R 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) between them or
other rail-mounted devices!
It may result in overheating and
device failure!
