Overview

Safety modules for AS-Interface (ASIsafe modules) are available

for field use in degree of protection IP67 (K20F, K45F and K60F

compact modules) and for the control cabinet (S22.5F SlimLine

modules) in degree of protection IP20:

K45F compact safety modules for operation in the field

The K45F compact safety module is equipped with two "safe" in-

puts. For applications up to Category 2 according to EN 954-1

the two inputs can be assigned separately. If category 4 is re-

quired, a two-channel input is available on the module.

K60F compact safety modules for operation in the field

The K60F compact safety module similarly has two standard out-

puts in addition to two safety inputs (see K45F for categories);

power is supplied from either the yellow AS-Interface cable or as

auxiliary voltage from the black 24 V DC cable.

K20F compact safety modules for operation in the field

Being only 20 mm wide, the K20F module is particularly well

suited for applications where modules need to be arranged in

the most confined space. The K20F modules are connected to

the AS-Interface with a round cable with M12 cable box instead

of with the AS-Interface flat cable. This enables extremely com-

pact installation. The flexibility of the round cable means that it

can also be used on moving machine parts without any prob-

lems. The K20 modules are also ideal for such applications as

their non-encapsulated design makes them particularly light in

weight.

S22.5F SlimLine safety modules for operation in control

cabinets and local control cabinets

The S22.5F SlimLine safety module has two safety inputs. The

safe connection of signals to ASIsafe networks in the cabinet is

also possible therefore. For operation up to Category 2, both in-

puts can be separately assigned; if Category 4 is required, a

two-channel input is available on the module.

New in the range are two S22.5F module versions which have

two standard outputs in addition to the two safety inputs; power

is supplied either from only the yellow AS-Interface cable or as

auxiliary voltage from the black 24 V DC cable.
