In case a N-switching output module is positioned within a

safety segment the connected load needs to be switched

a24 V Safe.

The relay output modules UR20-4RO-CO-255 and UR20-

4RO-SSR-255 are not safely switchable, therefore they must

not switch any safety function.

The digital counter module UR20-1CNT-1DO-100 will not be

switched since it is supplied via the input current path.

4.4 Configuration

A PF-O-xDI-SIL module can be positioned anywhere in

the u-remote station. Multiple PF-O-xDI-SIL modules

and thus safety segments can be set up in a single station.

When planning a u-remote station with PF-O-xDI-SIL

modules, the following requirements must be met:

–

The overall current consumption from the system current

path of all switchable modules within a safety segment

must be lower than 100 mA (see table in section 4.5

–

Each safety segment might include at most 12 switcha-

ble modules.

–

The switch-off delay time for the safe input channels

within a safety circuit is 500 ms ± 10 ms.

–

The load output is not designed for either inductive or

capacitive loads.

–

The feed-in of the PF-O-xDI-SIL module must be

safeguarded with a 8-A super fast fuse.

–

A SELV/PELV power supply must be used.

–

The safely shut-off systems/applications must get their

power exclusively from the safe feed-in module

PF-O-xDI-SIL. Likewise, it must not be possible to

feed external energy into the safety segment elsewhere.

–

Relay modules can be located within a safety segment,

however their outputs cannot be safely shut off in case of

a malfunction.

–

At the SS1 output of the UR20-PF-O-2DI-DELAY-SIL, only

systems/equipment that do not feed any power back into

the system in the event of a malfunction can be con-

nected.

–

Any external short circuits in the wiring of the safe output

must be avoided.

–

Fault exclusion as per EN ISO 13849-2 must be provided.

4.5 Switch-off delay time

The turn-off time of a PF-O-xDI-SIL module is 20 ms,

caused by the hardware and firmware delay time. The time

required until the output voltage even of the last switchable

module of a safety segment is below 5 V, can be calculated

as follows:

Turn-off time of a PF-O-xDI-SIL module

+ Sum of all modules’ hardware delay
= Switch off delay [ms]

Switch-off delay and current consumption

Hardware delay [ms] Current consumption
