Digital input module UR20-8DI-PN-FSPS, UR20-8DI-PN-FSPS-V2
Digital input module UR20-8DI-PN-FSPS (Best.-Nr. 1335070000), UR20-8DI-PN-FSPS-V2
(Best.-Nr. 2464590000)
The UR20-8DI-PN-FSPS or UR20-8DI-PN-FSPS-V2 digital in-
put module is a safe I/O module for the PROFIsafe protocol.
The module can detect up to 8 binary control signals. Two
sensors can be connected to each connector using a 2-wire,
3-wire or 4-wire connection. In the event that the available
supply current of 0.8 A per plug will not suffice, the sensor
supply must be realised using the auxiliary outputs of an-
other module (e.g. potential distribution module) within the
same power segment.
A status LED is assigned to each channel. The module elec-
tronics supply the connected sensors with power from the
input current path (I
)
IN
A test pulse check of the inputs can be parameterised as a
cross-circuit detection between input singal and supply volt-
age, between different input signals or other signals. Thus an
input gets active only when the signal of the dedicated aux-
iliary output is pending. The test pulses must be disabled if a
safety relay with OSSD outputs generating own test pulses is
connected.

Connection diagram UR20-8DI-PN-FSPS , UR20-8DI-PN-FSPS-V2
A safety sensor that is being connected in a dual chan-
nel mode (safety architecture of category 4 acc. to
DIN EN ISO 13849) must allocate the PN and the P-input of
one connector.
