Products information
The HIMA F3222 is an 8-channel input module specifically engineered for use with proximity switches
that comply with the EN 60947-5-6 (NAMUR) standard. It integrates two key functional features:
safety isolation to ensure signal integrity and prevent interference, and dedicated feeding capability
to power the connected proximity switches—making it a critical component for reliable signal
acquisition in industrial automation and safety-critical systems.
As a CE-certified product from HIMA (HIMA Paul Hildebrandt GmbH + Co KG), the F3222 is designed
to meet strict industrial performance requirements. Its electrical parameters are optimized for
NAMUR proximity switch compatibility: it has a precise switching point of 1.65 mA ± 0.2 mA, a
switching current difference of approximately 0.3 mA, and a switching time of around 10 ms to ensure
timely signal response . The module provides a dedicated sensor supply voltage range of 7.7...9 V to
power the proximity switches, while its own operation relies on two power inputs: 5 V DC (drawing 40
mA) and 24 V DC (drawing 75 mA) .
For physical installation and wiring, the F3222 features a compact design that requires only 4 SU
(Terminal Equipment units) of space, enabling easy integration into standard industrial control racks .
It uses a Z7108 front cable plug (with lead marking specified as Z 7108/3222/C..) and is compatible
with LiYY 16×0.5 mm² cables for signal transmission . The module’s 8 independent input channels
utilize differential wiring, with each channel connected to specific terminals (e.g., Channel 1 to
terminals d2 and d4, Channel 8 to terminals d30 and d32) and color-coded connections (e.g., white
for d2, brown for d4) to simplify wiring and maintenance . It also includes LED terminals (z4 to z30)
for real-time per-channel status indication, which aligns with its signal logic: an input current greater
than 2.1 mA triggers an H signal (activating the control channel), while an input current less than 1.2
mA triggers an L signal (deactivating the control channel) .
Additionally, the F3222 incorporates industrial-grade design elements such as screen connections to
reduce electromagnetic interference and compatibility with standard I/O bus interfaces, as depicted in
its block diagram . It is important to note that HIMA reserves the right to modify equipment
specifications without prior notice, ensuring the module can adapt to evolving industrial needs while
maintaining core functionality .
