Safe input and output module UR20-4DI-4DO-PN-FSOE, UR20-4DI-4DO-PN-FSPS
Safe input module UR20-8DI-PN-FSOE, UR20-8DI-PN-FSPS
The u-remote system provides variants of safe I/O modules
for the different safety protcols.
For Fail Safe over EtherCAT (FSoE):
– UR20-4DI-4DO-PN-FSOE (Order No. 1529780000): four
safe inputs, four safe outputs, two inputs and outputs
respectively can be parameterised P- or N-switching
– UR20-8DI-PN-FSOE (Order No. 1529800000): eight
inputs, four of which can be parameterised P- or N-swit-
ching
For PROFIsafe:
– UR20-4DI-4DO-PN-FSPS (Order No. 1335060000): four
safe inputs, four safe outputs, two inputs and outputs
respectively can be parameterised P- or N-switching
– UR20-8DI-PN-FSPS (Order No. 1335070000): eight
inputs, four of which can be parameterised P- or N-switch-
ing
Using safe I/O modules you can realise nearly all safety-rela-
ted functions via your PLC according to the designed safety
architectur, as for example:
– design up to four 2-channel safety circuits (AND-linked),
e.g. for emergency shutdown buttons, safety door con-
tacts and safety light grids
– shutdown up to four actuators safely
All product-specic information and notes on
the use of safe I/O modules can be found in
the Modules for functional safety manual.
The manual can be downloaded from the
Weidmüller website.
