Digital input module UR20-8DI-PN-FSOE, UR20-8DI-PN-FSOE-V2
Digital input module UR20-8DI-PN-FSOE (Best.-Nr. 1529800000), UR20-8DI-PN-FSOE-V2
(Best.-Nr. 2464600000)
The UR20-8DI-PN-FSOE or UR20-8DI-PN-FSOE-V2 digital
input module is a safe I/O module for the Fail-Safe-over-
EtherCAT (FSoE) protocol. The module can detect up to 8 bi-
nary 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 aux-
iliary outputs of another 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 auxil-
iary 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-FSOE, UR20-8DI-PN-FSOE-V2
A safety sensor that is being connected in a dual channel
mode must allocate the PN and the P-input of one connector
(safety architecture of category 4 acc. to DIN EN ISO 13849).
